------- Comment #2 from tom dot browder at gmail dot com 2008-08-24 22:07 ------- Andrew, you're right--it's not prohibited, but my argument is that it should be prohibited as the default build (but have a specific configure variable to allow it), at least until it is tested. Over the years I've watched people have a build problem, and the first thing the gurus tell them is *don't* build in the gcc tree, so this enhancement would at least get newbies' attention instead of continuing to waste help bandwidth. Note the recommendation to not build in the tree has been around I'll guess for at least ten years. And with the complexity of the build I doubt that the tested in-tree build will ever be a requirement for a release.
I envision a short but succinct message telling about the prohibition and adding a link to more detail. The installation instructions should perhaps have text enhancement or other edits to highlight the reason for the prohibition. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37210
