If so, you'll probably have a hard time with anything newer than GCC 4.7 which is the last version that can be compiled with a C90 compiler. While in theory GCC 4.8 and up should work with any C++98 compiler, this hasn't been tried with anything but g++ (and probably clang++) in a long time, so you're almost guaranteed to run into lots of problems. On Solaris 9, I'd strongly suggest to either build GCC 4.7 with a preexisting version of gcc (pretty much any version should do) or probably even Studio cc. If you like (and I'd recommend to try this), you should use this freshly built version of gcc 4.7 to bootstrap GCC 4.9 (the last version supporting Solaris 9). On Solaris 10, you have a preinstalled version of gcc 3.4.3 in /usr/sfw/bin to start from. In theory (I haven't tried this myself), this should be good enough to build even GCC 9, the last version supported on Solaris 10. If that fails for some reason, you can try to go via some intermediate version of gcc instead. In both cases I strongly recommend you thoroughly review the installation docs for the version of gcc you're building not to fall into traps that are already known. Besides, unless you're strictly wedded to GCC 4.8 for some reason, it's in your best interest to go for the last version of GCC supported on your Solaris versions which are certain to have all sorts of bugs already fixed.
