Let's say libtest.so containing three (3) files a.c b.c c.c. a.c: a() { printf("a"); } b.c: b() { b_printf("b"); } c.c: c() { c_printf("c"); } make them into regular library libtest.a and shared library libtest.so. creating test file test.c: main() { a(); } cc -o test test.c -ltest on all platforms, this cc will be successfully compiled and linked, but FreeBSD 3.0 complains : libtest.so: Undefined symbol '_b_printf' referenced from text segment libtest.so: Undefined symbol '_c_printf' referenced from text segment However, "cc -o test test.c -static -ltest" is happy when no shared library is used. So, it looks like just for linking shared library. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
