- Subject: [64bit] undefined references to _setjmp and _longjmp
/usr/include/machine/setjmp.h, which is included by
/usr/include/setjmp.h, declares _setjmp and _longjmp, but ld reports
"undefined reference":
$ cat test_setjmp.c
#include <setjmp.h>
int
main ()
{
jmp_buf j;
if (! _setjmp (j))
_longjmp (j, 1);
return 0;
}
$ gcc test_setjmp.c
