A least on amd64, gcc-3.4.6-r2 can't build dev-db/mysql-5.0.83 (see attached build.log). (gcc-3.4.6-r2 is keyworded amd64, dev-db/mysql-5.0.83 is ~amd64). If this can't be solved, there should be some code added to ebuild using gcc-major-version function to check for new enough gcc before going further. [I might understand if this is closed INVA due to mixing branches. (might, not will)]. Reproducible: Always Steps to Reproduce: 1. emerge =sys-dev/gcc-3.4.6-r2 2. gcc-config x86_64-pc-linux-gnu-3.4.6 && env-update 3. emerge =dev-db/mysql-5.0.83 Actual Results: Compile fails (see build.log extract) Expected Results: Compile succeed, or build fails with "You need GCC 4.x for >=dev-db/mysql-5.0.83 to be built."

It would take a lot of work to determine and specify minimum versions of gcc for all the ebuilds in the tree... but why stop there? How about maximum versions as well, how about min and max versions of binutils...? When it comes to dependencies on packages in the system set, it's more practical to just specify unusual requirements, like not being able to be built with the standard toolchain. Sorry, but 3.4.6 is marked as stable for the _3.4_ slot which is no longer considered part of the standard toolchain -- you just can't expect to compile recent versions of arbitrary packages with gcc 3.x. It is nice to still have an old gcc available for compiling old out-of-the-tree code that didn't yet get updated to the gcc 4 level of strictness, but gentoo maintainers have been using gcc 4 as system compiler for quite some time now. Maybe it's time to join us :)
Then I'll have to update my old server to something closer to my gcc-4.4/glibc-2.10 desktop. Thanks for your answer, and for your work.
