Does anyone know of a c compiler that has the argp.h file? Since its mainly for unix i thought DJGPP would, but it didnt.

Does anyone know of a c compiler that has the argp.h file? Since its mainly for unix i thought DJGPP would, but it didnt.
What's the header for?
The argp_parser function. Its an advanced argument parser.
I never heard of it.
You mean parsing things like:I found this though, but make of it what you will...
http://cvs.parisc-linux.org/obsolete/glibc/argp/
Is the entire libc obsolete?
Nope, that's an obsolete branch of the libc code for PA-RISC systems.
It's the only place I could find that had any source whatsoever. If you have a Linux installation somewhere you might have the source in it :)
Nope im running windows here.
:(
Umm...maybe Cygwin has it? I have it installed but not any of the source code.
www.cygwin.com
Nope i tried it already. Ming-W doesnt either. Are there any really good C compilers for windows?
Well, gcc if you can get Cygwin working ;)
2.95 works fine under mine, but I've been having difficulty getting GCC3 in - it compiles but can't install, so you'd have to set everything up manually.
Visual C++ generates the best code out of that and Borland FCLT 5.5, but I haven't had chance to peruse gcc3's windows output having not got it working yet :(
It was fine under linux though.
GCC for windows or DOS just plain sucks. (I want linux so bad!) Visual C++ isnt C, so it makes huge executables. Same with BC 5.5.
It does C as well.Quote:

Use files with a .c extension.
All C++ compilers "do" C. C++ is made from C. But the executables come out huge. Thats why i want a c compiler only.
Hmmm...some numbers for MSVC (release mode):
Static CRT: 27K
DLL CRT: 2.5K
I couldn't get it less than 2.5 in C mode even when messing with the CRT stuff, although I managed to link in some separately-compiled segments of the CRT (like printf).
However, the problem isn't with the generated code, it's with the libraries it uses.
Ok whats static CRT and whats dll CRT. And 27kb is still big. LCC can get it down to like 5. And thats with debug info i think.
CRT = C RunTime library
If you link it into your program, that's static. If it uses msvcrt.dll then that's dynamic (and considering msvcrt.dll HAS to be on every system, that's not really a problem).
Like I say, it's a problem with the layout of the libraries, or perhaps the linker. 27KB was when it brought all the file i/o stuff in which is a size killer for both C and C++.
Although, I got a printf equivalent by using wsprintf, GetStdHandle, and WriteFile. It works perfectly, and takes almost no space in the executable.
I think I get round most of these problems by just hacking out the bits of the CRT source I want and using the rest from kernel32.dll.
I will admit though, that a pure C compiler can get it down further, because the library doesn't need to support calling all the static initialisers.
I guess my only answer is to switch to Linux. I have to get my own computer first. So i guess ill just use DJGPP while im on windows.
hi.. i have a question maybe you can help me... how can i call a .txt file with the argp library, being the .txt file "archivo_carreras" and "archivo_estudiantes" These files are input and "archivo salida" is a .txt file too but it is the output of the program
i want to find something like this example:
./pre -F<archivo-estudiantes> -U<archivo-carreras> -o<archivo-salida>
