I am trying to get a set of nine *.c files (and nine related *.h files) to compile under Windows.
The code was originally designed in Linux to take command line arguments using the standard GNU-Linux/C library "getopt.h". And that library does not apply to building the C-code in Windows.
I want to ignore what my code does right now and ask the following question. For those of you familiar with this C-library "getopt.h": will it be possible to build and run my code in Windows if it depends on POSIX-style command-line arguments? Or will I have to re-write the code to work for Windows, passing input files differently (and ditching the "getopt.h" dependency)?
if you just want getopt to be used in visual c++ without other dependences, I have port the getopt.c from latest gnu libc 2.12, with all new features.The only difference is you have to use TCHAR instead of char,but This is very common in windows.
simply download the source, make, copy libgetopt.lib and getopt.h getopt_int.h to your project.
you can also make it using CMakeList.txt in the root dir.
download the source from github
There is a possibilty to use code from MinGW runtime (by Todd C. Miller):

I have created a small library with these files and CMake script (can generate a VS project):

You might try looking into glib-2.0 as an alternative. It would be a bit large for just needing an option parser. The up side would be having access to all the other wonderful toys in the glib.
Just to be honest, I haven't tried getting this to work (I stick mostly to Linux), so YMMV.

Oh, you might explore using mingw for the build environment, and visual studio for your IDE.

Anywho, hope this helps.
You are correct.
getopt()
is POSIX, not Windows, you would generally have to re-write all command-line argument parsing code.Fortunately, there is a project, Xgetopt, that is meant for Windows/MFC classes.

If you can get this working in your project, it should save you a fair bit of coding and prevent you from having to rework all parsing.
Additionally, it comes with a nice GUI-enabled demo app that you should find helpful.
Good luck!
From what I remember of
getopt.h
, all it does is provide a handy parser for processing argv from your main function:Windows console programs still have a main method, so you can simply loop through your argv array and parse the parameters yourself. e.g.
getopt()
is actually a really simple function. I made a github gist for it, code from here is below too
