This makes opening symlinks work universally in the build system tools. Two mechanisms have been implemented, both of which don't always work. The first is remapping via preprocessor macros. This fails where equally named methods are used (e.g. STL fstream::open()). The other is using hidden functions in the new libroot_build_function_remapper.a that is linked into everything that is linked against libroot_build.so. This one fails for functions that are defined inline in headers (Linux/glibc does that). Together they seem to cover our build system needs ATM. |
