cdecl linking

["Petter Wahlman" <pwa at norman dot no>]

'lo

i need to link cdecl functions with gcc, but can't modify the precompiled
library containing the respective functions. (The library is originaly
compiled under windows, and converted from pe-coff to i386-elf (linux)).

when linking (GNU ld 2.11.90.0.24) i get e.g "undefined reference to `_sprintf'"

the PE linker has the command line option '--enable-stdcall-fixup' which
might solve the above problem, but i have'nt yet had any success.

[100](petter):linking>gcc precompiledlib.c -c; gcc foo.c precompiledlib.o
-> OK
[100](petter):linking>gcc precompiledlib.c -c -DCDECL; gcc foo.c
precompiledlib.o
precompiledlib.o: In function `func':
precompiledlib.o(.text+0x77): undefined reference to `_sprintf'
collect2: ld returned 1 exit status

example code:

---[ foo.c ]---
#include <stdio.h>

extern char *func(char *);

int main(int argc, char **argv)
{
        if (argc < 2) exit(1);

        printf("%s\n", func(argv[1]));

        return 0;
}
#define PREFIX "Recived argument: "

---[ precompiledlib.c ]---
char *func(char *ptr)
{
        char *buf = (char *)malloc(strlen(PREFIX)+strlen(ptr)+1);
        if (!buf) {
                perror("malloc()");
                exit(1);
        }

#ifdef CDECL /* does not work */
        _sprintf(buf,"%s%s",PREFIX,ptr);
#else        /* works         */
        sprintf(buf,"%s%s",PREFIX,ptr);
#endif
        return buf;
}



Thanks
