Be sure crt0+.o is in /usr/local/lib/. =============================== README: APPLY THIS DIFF TO g++/config/tm-sun3.h .... ** BUT FIRST ** notice that it is a symbolic link! SO -- copy g++/config/tm-sun3.h somewhere, remove the link, and copy it back. BECAUSE you don't want these diffs in the "gcc" -- only in the "g++". WHAT THESE DO: make g++ look for the c runtime "crt0+.o" rather than the usual "crt0.o". "crt0+.o" knows how to initialize global and static objects with constructors, using lists make by g++'s ld++ linker, which has a built-in muncher (rather than using a separate munch program like at&t does). If you use this on something besides a sun3, you may have to make similar diffs to other dot-h files. strick ========================== *** tm-sun3.h.orig Wed Feb 22 09:27:23 1989 --- tm-sun3.h Tue Jul 4 15:20:39 1989 *************** *** 77,84 **** #if TARGET_DEFAULT & 0100 /* -mfpa is the default */ #define STARTFILE_SPEC \ !
