[Mingw-users] Mingw, GCC, C and assembler

[Francky <fra...@fr...>]

Hello,

I'am using Mingw to write a program with both C and assembler sources (.c
and .s) and it works pretty well.

Now, I'm trying to compile and link my work on Linux using gcc. I use almost
the same makefile (and exactely the same compiler and linker options).

When using mingw under Windows, its generates a '_' before each function
(using gcc -S myfile.c, for instance). So, for instance, in order to call
"printf" into my .s files, I push my stuff and call '_printf'. Same thing
when I uses global variables defined into C source into assembler code.

Now, under Linux/gcc, it does not generate this little '_' before functions
or global variables. And when I try to link my work, I have hundred of link
errors because of that.

I could use some conditional #define into my assembler files in order to
correct this, but perhap's a compiler or linker option exist, or I have
missed something.

So is there a way to correct this (not using '_' with mingw or using '_'
with gcc into assembler code) ? Of course, something that works with calling
convention using msvcrt.dll in the first case, and gcc libraries in the
second.

Thanks,
Franck
