While extensions link to libperl.so that itself links to libpthread.so that defines pthread_getspecific symbol, the extensions linking fails because they use dTHX macro, provided by included thread.h via perl.h, that expands to pthread_getspecific. In other words it looks like -z defs requires that all used symbols are provided by directly linked libraries. I.e. we will have to patch Perl so that extensions add -lptrhread to the linker flags. I don't say this not a bug in Perl, but just that Perl is affected. -- Petr _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx
