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. First you must make sure Configure and make - don't find /usr/ucb/cc. (It must use gcc or the native C - compiler: /opt/SUNWspro/bin/cc) - - Some questions need a special answer. - - Are your system (especially dbm) libraries compiled with gcc? [y] y - - yes: gcc 2.3.3 or later uses the standard calling - conventions, same as Sun's C. - - Any additional cc flags?

Solaris 2.7 and above will run in either 32 bit or 64 bit mode, - via a reboot. - 2. You can build 64 bit apps whilst running 32 bit mode and vice-versa. - 3. 32 bit apps will run under Solaris running in either 32 or 64 bit mode. - 4. 64 bit apps require Solaris to be running 64 bit mode - 5. It is possible to select the appropriate 32 or 64 bit version of an - app at run-time using isaexec(3). - 6. You can detect the OS mode using "isainfo -v", e.g. - fubar$ isainfo -v # Ultra 30 in 64 bit mode - 64-bit sparcv9 applications - 32-bit sparc applications - 7. To compile 64 bit you need to use the flag "-xarch=v9". - getconf(1) will tell you this, e.g. - fubar$ getconf -a | grep v9 - XBS5_LP64_OFF64_CFLAGS: -xarch=v9 - XBS5_LP64_OFF64_LDFLAGS: -xarch=v9 - XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9 - XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9 - XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9 - XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9 - _XBS5_LP64_OFF64_CFLAGS: -xarch=v9 - _XBS5_LP64_OFF64_LDFLAGS: -xarch=v9 - _XBS5_LP64_OFF64_LINTFLAGS: -xarch=v9 - _XBS5_LPBIG_OFFBIG_CFLAGS: -xarch=v9 - _XBS5_LPBIG_OFFBIG_LDFLAGS: -xarch=v9 - _XBS5_LPBIG_OFFBIG_LINTFLAGS: -xarch=v9 - - > > Now, what should we do, then?
