Ah I see, when I build I specify the base compiler used (currently using the RH 8 compiler for C/Ada, but I have most ACT public and customer releases installed also), where to build (somewhere/build-TIMESTAMP) and where to install (somewhere/install-TIMESTAMP), I never configure to the base compiler. I assume you target some root only location. I've a few dozens installed compilers, any other scheme wouldn't work at all. The scheme is quite handy to do regression search, testing build with various base compilers or testing the new testsuite with old builds, etc... Everything's automated (with hook for patch) so uncaught mistakes are unlikely. Are other developper always configuring to root or is Richard's practice uncommon? -- Laurent Guerby
