You could solve the problem that way, if you wanted to bundle the builds together, sure. I try to avoid that, obviously. YMMV. If you want to contribute such a source-post hook, please make it off by default, turned on by an [options] flag. BTW, I'll have downloadable builds of gcc44 thru gcc47 on RHEL5/6 available shortly. > 2- Are there some test cases out there for multilib handling?

First of all, the "test suite" for builds of gcc isn't even used, since it requires autogen, and I've never had much luck getting that (and it's myriad dependencies) to build. Are you talking about getting the normal gcc test suite to work, or are you talking about building a distribution of some other software that will test/verify the multilib bits? In general, the efsdeploy build system avoids the need for using the multilib stuff by providing both 32 and 64 bit native tool chains, that produce the right default output. In practice, that means you very rarely build a 32 bit binary using the 64 bit compiler, or vice versa (that does work, BTW, on some platforms). > 3- I notice fortran just got removed. Do people actually need > Objective C? (ie, --enable-languages objc) I have no idea -- I've always built gcc with those languages, and added fortran when it worked, an wasn't a PITA to build. In the 25 years I've been building gcc for people, I've very rarely had requests for fortran. I can count them on one hand, I think. If someone uses all this stuff, and needs fortran, they can easily do a test build with modified rules that try to add fortran to the mix, and you'll see where I got stuck. _______________________________________________ EFS-dev mailing list [email protected] http://mailman.openefs.org/mailman/listinfo/efs-dev
