I guess for the two or three people who even run this stuff (no doubt to run Oralce and it’s draconian licensing) you can find out all about it here.
It appears they still keep the Fortran stuff around for it… Oh and this release is x86_64 only. Sorry 32bit users.
Installing gcc (and I imagine everything else) revolves around the pkg command… In this case ‘pkg install gcc-3’ will download and install gcc 3. While ‘pkg install gcc-45’ will install GCC 4!. Don’t forget to install system/header or you won’t have things like stdio.h!!
Another GCC tidbit, is that you can build 64bit binaries with GCC 4.5 by supplying the -m64 flag!
While Solaris 11 installs somewhat quickly in VirtualBox (but wow does it take forever to boot), it is bare minimum…
