I need to create a Lua binary for Windows that is fully portable, meaning that I can have it on a flash drive and it will work on any Windows computer (well, Windows 7 computer). I need at least a few additional libraries including Lua socket, a library that allows the proper storage (without rounding at all) and computation of large numbers (around 81 digits in total), and the rs232 library.
The problem is that I don't know how to compile them together into a binary, or if I can use some method to just use a plain Lua binary and use require to add the others. I've been researching this for a long time (a few weeks now) and haven't been able to find a solution. If anyone can help, it would be greatly appreciated.
If it makes the process any easier, I do have a Linux operating system I can use if necessary.
Answer: if you are using Windows, you can get the .dll files for each library and add them to your Lua directory. I now have a version of Lua with all of the libraries I wanted, plus a few more. Thank you everyone for your help.
I have downloaded the sources, then... I don't know what I'm supposed to do.
I think that we have to compile these, but I'm not really familiar with java.
Do you have a complete example for use it ?
The java2dart tool was written for Google's own use, to help convert many of the tools from Java into Dart. Is was not intended to support conversion of all Java apps; just what was required to get things like the IDE tools (Analyzer, etc.) into Dart.
As such, there's not a huge amount of info on what it can/can't do or the best way to use it. It is written in Java, and there doesn't appear to be a pre-built binary; so it would almost certainly involve compiling the Java yourself. Unfortunately I have almost zero experience with Java (or fortunately, depending on your point of view :))
You can find a little info on this in the Dart Google Group here:
https://groups.google.com/a/dartlang.org/d/msg/misc/4mSK-M7dm2U/ARbTh6emb-sJ
I wonder whether anyone has tried running java2dart on java2dart to get a nice Dart version? :) Or even then running it through dart2js to get a JavaScript version! ;)
Can someone point to me where I can find Finite Element Delphi library.
Preferably opensource.
Never tried, no releases, but source code is available: http://oofem.codeplex.com/
However, this CodePlex project appears to require the MtxVec math library from Dew Research which is not open source or free. (Note the 'uses MTxVec' in the source code).
Edit:
I accepted the answer: It's sofar the only advanced opensource Delphi I come accross.
To share my other findings, I suggest the following french resources (in academia):
Méthode des éléments finis: programmes écrits en Pascal (source code samples in Delphi).
RDM 6.17 (Binary distribution only).
I don't know of any that exist anymore since the heyday of Pascal being used for numerical methods work in the 80's. You best bet is to look into the C++ or FORTRAN projects listed at: http://en.wikipedia.org/wiki/List_of_numerical_libraries and either convert the code or link to the binaries. If you can use a commercial library, the NAG library has a write up on using Delphi with their DLLs at: http://www.nag.com/numeric/BorlandDelphi.asp.
You can also try here, scroll down to 'Free/Open Source/Shareware Packages' - lots listed, but language is not specifed.
Can anybody tell me how to find or create a binding to OpenCV for GNAT?
I want to use Ada2005 to implement some program with OpenCV (1.0 or 2.X),
but I don't know how. Can anybody teach me how to do it?
Teaching you how to create a binding to a complex library is beyond the scope of StackOverflow, but you might start with this tutorial. Then study the relevant GNAT library sources, e.g. Ada.Numerics, and other existing Ada bindings. Among others, Ada 2005 Math Extensions and An Ada binding to the GNU GMP and MPFR Multiple Precision libraries are exemplary as well as accessible.
If you have Gnat Pro (and presumably a support contract from ACT), I think you can get a binding generator from them.
In the comments, Simon Wright pointed out that you can get this binding generator from GCC 4.6.0., which is the official (although sometimes a bit behind) GCC distribution. I generally suggest folks who aren't paying ACT customers get their compiler from GCC, rather than the GNAT GPL version from ACT.

Improve this question
I am curious about what tools are used to build the next version of themselves.
For example, Delphi has long claimed that "Delphi is written in Delphi".
I assume Visual Studio is written using Visual Studio.
What are some other examples of tools that written in themselves?
Interestingly, the VB.NET & C# compilers themselves are written in unmanaged C++ (leading to the C++ team's T-Shirt: "My compiler compiled yours"). The C# team hopes to have a fully managed-C# hosted C# compiler for VS2010.
Bjarne Stroustrup mentioned in The Design and Evolution of C++ that the first C++ compiler was written in C++.
I've just noticed this is also a question in his FAQ:
The first C++ compiler (Cfront) was
written in C++. To build that, I first
used C to write a "C with
Classes"-to-C preprocessor. "C with
Classes" was a C dialect that became
the immediate ancestor to C++. That
preprocessor translated "C with
Classes" constructs (such as classes
and constructors) into C. It was a
traditional preprocessor that didn't
understand all of the language, left
most of the type checking for the C
compiler to do, and translated
individual constructs without complete
knowledge. I then wrote the first
version of Cfront in "C with Classes".
This is off-topic, but strictly speaking, it is an example of a tool which builds itself.
The reprap - an open-source 3d prototyping machine, which recently gave 'birth' to "its first complete working replicated copy".
I love this kind of stuff.
Generically speaking, C compilers are usually written in C... *nix kernels are compiled on *nix, etc.
Also, there's the pypy project which provides a Python interpreter written in Python.
When gcc (the Gnu C compiler http://gcc.gnu.org/) was not available widely, you had to compile it from source, compiling stage1 compiler, then compile stage2 with stage1, till you have your final compiler. I assume it must be the same today.
Here is another example: Mono's C# compiler is self hosting - i.e. it's written in C# and used to compile itself.
Dog fooding refers to the more general practice of a company using its own product internally, especially during its development.
Lots of folks like to look at how Lisp can be implemented in Lisp.
Squeak is a Smalltalk-80 implementation written in itself.
even its virtual machine is written entirely in Smalltalk making it easy to debug, analyze, and change.
Sun's Java compiler has long been written in Java. However, recent work is writing a JIT compiler in Java as well. This is the JVM component that converts Java byte code to native processor instructions.
We use to develop using RealBasic. The IDE is written in itself, or so I've been lead to believe.
ghc, the Haskell compiler, is mostly written in Haskell.
tcc is another self-hosting C compiler for x86 and ARM. Its claim to fame is being, well, tiny (100k or so for preprocessor, compiler, assembler, and linker).
I would assume that pretty much any tool that's part of the typical development process would be involved in its own development, to whatever extent possible. This includes:
certain programming languages, especially compiled ones
IDEs
text editors
version control systems
bug trackers
build systems
If you're on a team building one of these tools, and you're not developing it for a specific niche that doesn't apply to your team, I don't know why you wouldn't use it to build itself. Having developers be users of the product is one of the best ways to find possible improvements.
For the AmigaOS there was a third party Basic interpreter (don't remember the name) for which you could later buy a compiler. The compiler was delivered as source, so you had to use the interpreter to run the compiler to compile itself...
To cite Kent Beck:
...it may seem a bit like performing brain surgery on yourself.
Visual Studio and Team Foundation Server build themselves. It's called dogfooding, a term which if not originating in Microsoft, it certainly likes
Oracle Application Express is a web application development tool that is built in itself.
Eclipse IDE is generally built and developed using Eclipse IDE.
It is fairly typical to have a languages compiler written in its own language. This is called self-hosting or bootstrapping.
Maven2 is built using Maven2.
Ok, it's not built (i.e. written) using itself, as it is a tool to build (i.e. compile) project, but it is using its own code to compile...
I was amazed with JSLint
In short it has been described as Javascript "compiler" using javascript.
I am building an IDE-based code generator, and I am using it to build itself. If fact, as Stroustrup did, I am first building a valid generator model and using a pre-processor to build the final C++ code to compile. Once I have a good working version of the IDE, I'll start using it to build further versions of itself.
It's like giving a new dimension to the meaning of "recursive programming"!
AFAIK does the OpenJDK build itself first with the installed java and afterwards with itself.
Naturally the Jetbrains team uses its own IDE IntelliJ IDEA to develop this IDE.
I assume this is true for most IDE vendors.
As far as I know, when building EMACS from source, all of the ELISP code is bootstrapped. I found that quite noteworthy.
Not quite what you're asking for, but the entire development environment for Revolution http://www.runrev.com is built using Revolution itself, and the source (except for small parts that enforce the license) is completely exposed in source form. So if you don't like the way the dev environment is implemented, you can change it. Find a bug, fix it. You can also easily build additional development tools and integrate them.
Ada and Forth
I gave the Smalltalk-80 answer an uptick. Best, most elegant example I can think of. The question also reminds me of a slightly related problem that used to be popular: write a program that outputs itself. Not the same level of bootstrapping, but a fun little programming puzzle for your amusement. Maybe not possible in all languages?
The old Watcom C/C++ compiler was built using itself.
Kragen Sitaker's Ur-Scheme is a fine example of a small nontrivial compiler written in itself. That page links to several more good sources in that vein.
