Hi,
Weird. It seems like gc(1)/ld(1) has changed the way -pthread is handled. In 6.X
and below it will record a NEEDED entry for libpthread even if the executable
doesn't reference any pthread symbols. I suspect that in 7.X if the executable
doesn't reference any pthread symbols it wont record the NEEDED entry.
You can verify that for me with the following test on 7.0:
=== k.c ====
int
main(void) {
return 0;
}
=========
$ cc k.c -pthread && ldd a.out
a.out:
libpthread.so.2 => /usr/lib/libpthread.so.2 (0x80062a000)
libc.so.6 => /lib/libc.so.6 (0x800755000)
Do you get similar ldd output on 7.0?
-Kurt
