--- Comment #36 from Andrew Eikum aeikum@codeweavers.com --- (In reply to Rafał Mużyło from comment #34)
That check is nevertheless bogus - sizeof(gint64) by design is *always* 8.
With the correct glib headers for your architecture, yes, it is always 8. But without setting PKG_CONFIG_PATH to pick up the correct glib-2.0.pc file, it will be wrong. This is what the configure check is for.
[aeikum@aeikum ~]$ cat test.c #include <stdio.h> #include <glib-2.0/glib.h>
int main(int argc, char **argv) { printf("%u\n", sizeof(gint64)); return 0; } [aeikum@aeikum ~]$ gcc $(pkg-config --cflags --libs glib-2.0) -o test test.c [aeikum@aeikum ~]$ ./test 8 [aeikum@aeikum ~]$ gcc -m32 $(pkg-config --cflags --libs glib-2.0) -o test test.c [aeikum@aeikum ~]$ ./test 4 [aeikum@aeikum ~]$ gcc -m32 $(PKG_CONFIG_PATH=/usr/lib32/pkgconfig pkg-config --cflags --libs glib-2.0) -o test test.c [aeikum@aeikum ~]$ ./test 8 [aeikum@aeikum ~]$
