I have tried to build GCC on two solaris9 systems, for the slower of which I've only built the C compiler. The build scripts are at present: http://www.eng.cse.dmu.ac.uk/~hgs/build-gcc-brains.ksh Just cc -- in fact only using the gcc-core tarball. http://www.eng.cse.dmu.ac.uk/~hgs/build-gcc-neelix.ksh no java, or ada, or fortran based on the full tarball. And the results for each machine are at: http://www.eng.cse.dmu.ac.uk/~hgs/gcc-4.1.1-build-ksh-brains http://www.eng.cse.dmu.ac.uk/~hgs/brains-gcc-4.1.1-config.log http://www.eng.cse.dmu.ac.uk/~hgs/gcc-4.1.1-build-ksh-neelix http://www.eng.cse.dmu.ac.uk/~hgs/neelix-gcc-4.1.1-config.log (I know putting this on the web is less helpful for the archive, but I'm not sure what would be useful to include from the large amount of text. Feel free to paste relevant bits into the thread later.) I have a number of problems: 1 Fixincludes fails, and I can't see why this is. Most of my gnu tools are up to date. 2 The build takes a long time. Well, the machines are old, so that's fair enough I suppose. I'm wondering how long I should expect a build to take on a modern system. If my machine is more than twice as slow this might help me when trying to get funding for an upgrade. The long time means it is inconvenient to change things repeatedl until they work. 3 I can't seem to build gmp -- at least gmp passes its tests and then guile complains it is not built, and GCC seems to think it is not there either. So at present I'm trying to upgrade GCC as a means to compile gmp in order to compile the whole of GCC correctly. What else would be useful information? Thank you, Hugh
