Hi,
It looks like the realpath and canonicalize_file_name posix calls are
missing from msys2.
#define _GNU_SOURCE
#include <limits.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
realpath("test", NULL);
canonicalize_file_name("test");
return 0;
}
On linux:
11:15:48 folkert@belle:~⥠40s $ gcc can.c
11:15:51 folkert@belle:~⥠$ ./a.out
11:15:53 folkert@belle:~⥠$
On msys2:
FHE@Hawking MINGW64 ~/Cornerstone/G4Platforms/G4Cpp/03G4Parsing
$ gcc can.c
can.c: In function 'main':
can.c:7:10: warning: implicit declaration of function 'realpath'
[-Wimplicit-function-declaration]
realpath("test", NULL);
^~~~~~~~
can.c:9:11: warning: implicit declaration of function
'canonicalize_file_name' [-Wimplicit-function-declaration]
canonicalize_file_name("test");
^~~~~~~~~~~~~~~~~~~~~~

C:\msys2\tmp\ccSvFse3.o:can.c:(.text+0x2d): undefined reference to
