To solve this problem: b' :-) b') build the shared library that links against libobjc without "short data". It's a hack because not using short data pessimizes access sequences and thus reduces performance. > I found only a "--disable-short-wchar" option ... ... which is unrelated :-) The best solution is to build libobjc.so. I did that and it solved the problem, but exposed another one. If we don't want libobjc.so, we have to build libobjc.a with PIC, which terribly failed on i386 so that we have to make it ia64 specific to start with (even though it's theoretically required on all architectures). -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ia64" in the body of the message
