![]() NAS currently has 16 MATLAB licenses available. To avoid overwhelming the license server, and to reduce contention for the limited number of licenses, PBS batch jobs running on Pleiades and Merope are not allowed to query the MATLAB license server. Therefore, in order to run a MATLAB script in a batch job on Pleiades or Merope, you must first compile the script. Compiled executables do not access the license server.Note: It is not necessary to compile your MATLAB scripts for batch jobs running on the LDANs or Endeavour—on these systems, there is less risk of overwhelming the MATLAB license server because fewer hosts query the server. Also, you can still run interactive MATLAB jobs on Pleiades and Merope without compiling the scripts (it is easier to debug the scripts if they are not compiled into executables). Steps for Compiling a MATLAB ScriptThis method is the simplest way to compile a MATLAB script into a standalone executable. ![]() I have the 1.7 version with regular license and maintenance period expire on 2018. Although this the last compiled version of my application return a problem when other users (not me) launch it and appear and alert box with message as objects “Created with Unlicensed Compiler, you may not distribute the invisible exe with the free version of the compiler” What mean? Today we make a big step. Yes, thats right, the open beta from austrian war mod. Warning: It can contain bugs or unfinished stuff, there are coming patches if there are any big bugs! ITS ONLY A BETA, also think, there are only 6 maps, in the final version there. When you install an MPLAB XC C compiler, you are installing an unlicensed compiler. This means that you are running under a FREE license and you have access to the minimum amount of code optimization and support. No mention of what app you used to create your EXE programs. Option to Compile your batch files to run completely Invisible. Right-Click Windows context. Created with Unlicensed Compiler, you may not distribute the invisible exe with the free version of the compiler. Although this the last compiled version of my application return a problem when other users (not me) launch it and appear and alert box with message as objects “Created with Unlicensed Compiler, you may not distribute the invisible exe with the free version of the compiler” What mean? The Power C compiler and the Abacus C compiler both ran on the C=64, but weren't completely K&R. Am I imagining it the morning after, or was the cover of Gordon's 'white book' actually blue? The 1541 5.25' serial floppy drive was painfully slow compared to the hard drive on a PC clone of that era. The steps are described using the following sample script, findR.m: function R = findR% findR - given data T, calculate R%T = 10;R =.5.(-9.8).T% end of MATLAB codeComplete these steps to compile the sample script:. Load the modules:% module load matlab% module load gcc/4.7.3 # or later. If this is the first time you are using MATLAB to create an executable, run:% matlab -nodisplaymbuild -setupexit. Compile the script into an executable. Advanced compilers like gcc compile codes into machine readable files according to the language in which the code has been written (e.g. C, C, etc). In fact, they interpret the meaning of each codes according to library and functions of the corresponding languages. Correct me if I'm wrong.I wish to better understand compilers by writing a very basic compiler (probably in C) to compile a static file (e.g. Hello World in a text file). I tried some tutorials and books, but all of them are for practical cases. They deal with compiling dynamic codes with meanings connected with the corresponding language.How can I write a basic compiler to convert a static text into a machine readable file?The next step will be introducing variables into the compiler; imagine that we want to write a compiler which compile only some functions of a language.Introducing practical tutorials and resources is highly appreciated:-). IntroA typical compiler does the following steps:. Parsing: the source text is converted to an abstract syntax tree (AST). Resolution of references to other modules (C postpones this step till linking). Semantic validation: weeding out syntactically correct statements that make no sense, e.g. Unreachable code or duplicate declarations. Equivalent transformations and high-level optimization: the AST is transformed to represent a more efficient computation with the same semantics. This includes e.g. Early calculation of common subexpressions and constant expressions, eliminating excessive local assignments (see also ), etc. Code generation: the AST is transformed into linear low-level code, with jumps, register allocation and the like. Some function calls can be inlined at this stage, some loops unrolled, etc. Peephole optimization: the low-level code is scanned for simple local inefficiencies which are eliminated.Most modern compilers (for instance, gcc and clang) repeat the last two steps once more. They use an intermediate low-level but platform-independent language for initial code generation. Then that language is converted into platform-specific code (x86, ARM, etc) doing roughly the same thing in a platform-optimized way. This includes e.g. The use of vector instructions when possible, instruction reordering to increase branch prediction efficiency, and so on.After that, object code is ready for linking. Most native-code compilers know how to call a linker to produce an executable, but it's not a compilation step per se. In languages like Java and C# linking may be totally dynamic, done by the VM at load time. Remember the basics. Make it work. Make it beautiful. Make it efficientThis classic sequence applies to all software development, but bears repetition.Concentrate on the first step of the sequence. Create the simplest thing that could possibly work. Read the books!Read the by Aho and Ullman. This is classic and is still quite applicable today.is also praised.If this stuff is too hard for you right now, read some intros on parsing first; usually parsing libraries include intros and examples.Make sure you're comfortable working with graphs, especially trees. These things is the stuff programs are made of on the logical level. Define your language wellUse whatever notation you want, but make sure you have a complete and consistent description of your language. This includes both syntax and semantics.It's high time to write snippets of code in your new language as test cases for the future compiler. Use your favorite languageIt's totally OK to write a compiler in Python or Ruby or whatever language is easy for you. Use simple algorithms you understand well. The first version does not have to be fast, or efficient, or feature-complete. It only needs to be correct enough and easy to modify.It's also OK to write different stages of a compiler in different languages, if needed. Prepare to write a lot of testsYour entire language should be covered by test cases; effectively it will be defined by them. Get well-acquainted with your preferred testing framework. Write tests from day one. Concentrate on 'positive' tests that accept correct code, as opposed to detection of incorrect code.Run all the tests regularly. Fix broken tests before proceeding. It would be a shame to end up with an ill-defined language that cannot accept valid code. Create a good parser. Pick whatever you want. You may also write your own parser from scratch, but it only worth it if syntax of your language is dead simple.The parser should detect and report syntax errors. Write a lot of test cases, both positive and negative; reuse the code you wrote while defining the language.Output of your parser is an abstract syntax tree.If your language has modules, the output of the parser may be the simplest representation of 'object code' you generate. There are plenty of simple ways to dump a tree to a file and to quickly load it back. Create a semantic validatorMost probably your language allows for syntactically correct constructions that may make no sense in certain contexts. An example is a duplicate declaration of the same variable or passing a parameter of a wrong type. The validator will detect such errors looking at the tree.The validator will also resolve references to other modules written in your language, load these other modules and use in the validation process. For instance, this step will make sure that the number of parameters passed to a function from another module is correct.Again, write and run a lot of test cases. Trivial cases are as indispensable at troubleshooting as smart and complex. Generate codeUse the simplest techniques you know. Often it's OK to directly translate a language construct (like an if statement) to a lightly-parametrized code template, not unlike an HTML template.Again, ignore efficiency and concentrate on correctness. Target a platform-independent low-level VMI suppose that you ignore low-level stuff unless you're keenly interested in hardware-specific details. These details are gory and complex.Your options:. LLVM: allows for efficient machine code generation, usually for x86 and ARM. CLR: targets.NET, mostly x86/Windows-based; has a good JIT. JVM: targets Java world, quite multiplatform, has a good JIT.Ignore optimizationOptimization is hard. Almost always optimization is premature.Generate inefficient but correct code. Implement the whole language before you try to optimize the resulting code.Of course, trivial optimizations are OK to introduce. But avoid any cunning, hairy stuff before your compiler is stable. So what?If all this stuff is not too intimidating for you, please proceed! For a simple language, each of the steps may be simpler than you might think.Seeing a 'Hello world' from a program that your compiler created might be worth the effort. If you really want to write machine readable code only and not targeted to a virtual machine, then you will have to read Intel manuals and understand.a. Linking and Loading Executable code.b. COFF and PE formats(for windows), alternatively understand ELFformat(for Linux). c. Understand.COM file formats(easier than PE). d. Understand assemblers. e. Understand compilers and code generation engine in compilers.Much harder done than said. I suggest you to read Compilers and Interpreters in C as a starting point(By Ronald Mak). Alternatively, 'lets build a compiler' by Crenshaw is OK.If you don't want to do that, you could as well write your own VM and write a code generator targeted to that VM. Another starting point:. Great Book By Kenneth Louden:Tips: Learn Flex and Bison FIRST. Then go on to build your own compiler / VM.Good Luck! DIY approach for simple compiler could look like this (at least that's how my uni project looked like):. Define Grammar of the language. Context-free. If your grammar isn't LL(1) yet, do it now. Note, that some rules that looked ok in plain CF grammar may turn out ugly. Perhaps your language is too complex. Write Lexer which cuts stream of text into tokens (words, numbers, literals). Write top-down recursive descent parser for your grammar, which accepts or rejects input. Add syntax tree generation into your parser. Write machine code generator from the syntax tree. Profit & Beer, alternatively you can start thinking how to do smarter parser or generate better code.There should be plenty of literature describing each step in detail. 0 0 0 Share this.By now you should be aware that it is illegal to operate as an unlicensed contractor in the state of California. If this is the first time you’re reading this, then make sure you check out our other post on. A big part of the reason that there are so many unlicensed contractors in the state is because so many don’t even know it is illegal.In this post, we’re going to go over the unlicensed contractor california laws and help drill home the reasons that you should always, always, always,. It Is Illegal to Operate as an Unlicensed ContractorLet’s just say it again: It is ILLEGAL to both operate as an unlicensed contractor and to hire an unlicensed contractor. Both sides of the equation can be held liable in certain situations.Contracting jobs in the state of California require that the contractor have a valid license from the Contractors State Licensing Board (CSLB). There is not one all-encompassing license either — the contractor needs to have the specific license intended for their area of work. One license cannot be used for another job in another specialty.Specifically, those contracting jobs which have a cost of over $500 in materials and labor require the contractor to be licensed. Jobs under that threshold do not require a license, however, it is still in the homeowner’s best interest to use a licensed contractor for any job regardless of price. We’ll get into more on that later.For any job over $500, the contractor must provide their license number for any contract on which they place a bid. Using a license number that is assigned to another specialty, or one that is in any other way false, could lead to some severe penalties for the contractor.Regardless of the, there are still countless currently operating in California. Their low prices and the overall negligence of the public keeps this “underground economy” booming, but as more and more homeowners learn the potential consequences of hiring an unlicensed contractor, and likewise, the unlicensed contractors see the true risk in working without a license, perhaps the numbers will decrease.Having a license does not guarantee a homeowner that their contractor will do superior work, but it does assure them that they are protected if something goes wrong. Unlicensed contractors can offer no such assurances.Luckily, the California Contractors’ State License Law (“License Law”) is in place to protect homeowners against the unlawful practices of unlicensed contractors. The California Contractors’ State License Law Protects Homeowners Against Unlicensed ContractorsHomeowners and the general public do have an ally against unlicensed contractors in California: The California Contractors’ State License Law (“License Law”).This law was created to protect the public from incompetent and dishonest services by unlicensed contractors in the California construction industry. The law states that all California contractors must possess a valid contractor’s license unless that are able to meet a few narrow statutory exceptions. Those who do jobs under $500 also do not need a license.However, for those looking to bid on and work on larger projects, a license specific to the nature of work will be required. There are actually over 40 types of construction licenses each covering a specific specialty. Roofing jobs have their own set of licenses, plumbing and electrical work too. In order to legally complete these certain jobs, the specific matching license will be required and no license overlaps to another activity are allowed.The License Law also applies to workers not directly associated with construction, such as landscapers or tree trimmers, interior decorators, painters, and even sprinkler system installers. The Law covers work done not only to the physical home itself, but also the yard, driveway, garage, porch, pool and hot tub, and anything else on the homeowner’s property.The Law also covers materials, known as “home improvement goods,” which are used in the construction project and permanently affixed to the home. These goods might include heating and air conditioning equipment, carpeting, fencing, etc. Are There Any Situations In Which a License is Not Required?Yes, actually there are some situations where it is okay to hire an unlicensed contractor, at least legally.For example, any construction, improvements, repairs, or alterations made to personal property such as your television or computer does not require your contractor to be licensed. As we mentioned previously, home improvement jobs under $500 also do not require for your contractor to be licensed.The installation of any finished products, materials, or merchandise that does not become a fixed part of the home also is not covered under the law. Therefore, suppliers of finished cabinets or flooring do not need to be licensed, however, those who install the materials likely do. House cleaners and chimney sweepers do no need to be licensed either. What are the Potential Consequences for Unlicensed Contractors?Unlicensed contractor law is pretty stiff in the state of California, and those who operate without a license should be rather careful that they are not caught conducting their business. Hundreds of unlicensed contractors are caught each year, and some face rather serious penalties for not having a license.The California Contractors’ State License Law outlines that no person in California may perform any construction services billed at $500 or over, which can range from smaller repair jobs to the construction of an entire home. Obviously, bigger jobs will be easier for the authorities to catch someone who is unlicensed, however, contractors have been known to complete work on jobs big and small.The License Law is enforced by the Contractors State License Board (CSLB), which upholds construction standards throughout California and protect consumers. According to the CSLB, those who operate without a state-issued license actually cause harm to the public and thereby tarnish the respectability of the construction industry. The CSLB says this undermines California’s financial foundation. This Program Was Made With An Unlicensed Compiler In WindowsAs you can see, they take cracking down on unlicensed contracting very seriously.So serious in fact that those contractors who are caught operating without a license during a, or any other home improvement may have to appear before a Superior Court judge on misdemeanor charges. I recently ran my Lazarus program on afriend's Windows10 computer and several problems occurred.The first kink was that an error message said Windows couldn't find openal32.dll. My program uses OpenAl.pas etc. I did a search on my home computer for this file but the only place I found it was in the directory C:Windowssystem32 so I assume that the compiler created it.Do I need to make sure that the program copies this file to the Windows system folder when the program is installed?The other problem was that Windows10 repeatedly flashed a message that the program was made on an unlicensed compiler and asked whether to continue or not.Can anyone shed any light on this? The authors of OpenAL do know this. You are using a library that you installed on your computer. You could just use the same install-file to install it on all computers you want your program to run.I'm not sure why you would be irritated (embarrassed I can imagine). This Program Was Made With An Unlicensed Compiler In Windows 7You are a programmer, so if you use a dll from a third party YOU should know that you would need to distribute that dll to other computer for your program to run. That's just logical. (Maybe it's even in the documentation somewhere ). Mm Our messages were too close to call, but amount to the same.As a further note: windows 10 is not able to determine the compiler with what executable is built. It just looks for a signed binary. For that you can use several options:- self signed. In that case you have to accept that certificate on an application by application basis.- signed with a certificate from your own certificate tree (create your own root certificate first). This Program Was Made With An Unlicensed Compiler FreeI use this all the time on a per customer basis but with the same (my own) root. The root certificate needs to be accepted just once.- And Microsoft's preference: a certificate bought from Microsoft or a certificate issuer that has an intermediate MS certificate, which is ultimately signed through MS's certificate tree and with a MS root certificate. (Rather expensive for freeware) That will always work.
