[Mingw-users] simplest program => unknown type name 'size_t'

[R. M. M. <rob...@sa...>]

Hi, I’m a bit confused and getting nuts on a very simple problem. I program C since 25 years now, so it feels a bit dumb to ask this questions. But I’m stuck with mingw at the moment (BTW: I’m using the TDM version).

Here is my very unfancy problem / program:

#include <stddef.h>

int main(){
	return 0;
}


And I get, this error when I compile it using MSYS:

$ gcc -v test.c

Using built-in specs.

It’s definitely the case, that size_t wasn’t typedefed yet. But IMO this should by handled inside the system headers or am I wrong here?

Hope someone can enlighten me...

Hi Robert,

This mailing list does not support the version of GCC you're using - try 
the MinGW-w64 users list[1] instead. This is covered in TDM-GCC's README.

Your GCC installation appears corrupt. The same code compiles 
successfully with the same command line for me. Try installing TDM-GCC 
in an empty directory somewhere other than C:\MinGW.

Hi, sorry for that. Answering here to not tear apart the thread.

Thanks, that solved it. I think I made a mistake by having installed MinGW (the original one) once and than later added TDM-GCC, without cleaning things up. Works now.
