But isn't this the expected behaviour of using '-fwhole-program' on something that is not the whole program? I'm not sure if the option is supposed to be suitable for use when building a shared library, I'll ask on the mailing list. -- davek at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |davek at gcc dot gnu dot org Known to work| |4.3.4 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42904 ^ permalink raw reply [flat|nested] 7+ messages in thread
