Use +z or +Z to recompile. I don't know how crt0.o is getting in there, but if I invoke ld directly without that, the link works. There is probably an option that can be given to cc(1) so that it doesn't pass crt0.o to the linker, but I'm not seeing anything along those lines in the man page... ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2012-06-20 15:48 Daniel R.
