Or you ran fixincludes after installing gcc - w/o moving the gcc supplied varargs.h and stdarg.h files - out of the way and moving them back again later. This often - happens when people install gcc from a binary distribution. - If there's a tmp directory in gcc's include directory, fixincludes - didn't complete. You should have run "just-fixinc" instead. - - Another possible cause is using ``gcc -I/usr/include.'' - -6.1) Where is the C compiler or where can I get one? - - [...] - - 3) Gcc. - - Gcc is available from the GNU archives in source and binary - form. Look in a directory called sparc-sun-solaris2 for - binaries. You need gcc 2.3.3 or later. You should not use - GNU as or GNU ld. Make sure you run just-fixinc if you use - a binary distribution. Better is to get a binary version and - use that to bootstrap gcc from source. - - [...] - - When you install gcc, don't make the mistake of installing - GNU binutils or GNU libc, they are not as capable as their - counterparts you get with Solaris 2.x. - -6.9) I can't get perl 4.036 to compile or run. - - Run Configure, and use the solaris_2_0 hints, *don't* use - the solaris_2_1 hints and don't use the config.sh you may - already have.
