2. GNU gcc up to and including 3.4.6 you only needed GNU gcc source code to build gcc. With a little bit of persistence, it would even be possible to build gcc starting with another ANSI C-compiler, e.g. HP-UX C-ANSI-C. Now with gcc-4, it depends on GMP and MPFR That already sucks big time, as neither is fun to build with anything other than gcc, which you do not have (yet). Now with gcc-4.5 a third dependency was added: MPC, which is NOT available from the GNU ftp sites. I tried (on HP-UX 11.31) to build a 64bit gmp with gcc-4.2.4 I managed to build a long time back. Installed that, used it to build mpfr. So far so good. A few warnings that my gcc was too old. Yeah of course it is! If you make it close to impossible to stay recent, people eventually give up. Even the official HP Porting Center stooped after GNU gcc-4.2.3! After these two, I fount MPC, built and installed it and lo-and-behold, to no surprise gcc-4.5.0 was not able to pass configuration. Start again, now in 32bit mode ... GMP, MPFR and MPC got installed, and gcc didn't. Next plan: try to build a recent enough gcc to build 4.5.0. gcc-4.4.3? No, Fail gcc-4.3.4? No, Fail 32bit issues. Restart, build the startup trio with HP C-ANSI-C in 64bit mode GMP comes halfway and then fails in a gcc-ism. Let me cheat: compile that single object with gcc -mlp64 success. make Fail, as they use libtool, they seem to be unable to see that this compile was already done. They don't check on .o, but on vague and useless .lo files. SHOOT LIBTOOL TO HELL!
