One point of conflict is that we currently do not distinguish between configure, build, and install. Hence: * We cannot track installed files without serializing everything * We cannot simply set relative rpaths since configure will run binaries in the build directory (and not $SAGE_ROOT/local/bin) We also talked a bit about that at SD56 and the favored solution was to split build scripts into bash functions to separate configure/build/install, this is very similar to gentoo. We probably want to allow python build scripts, too, so similar functions in a Python script should be allowed as well. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
