Hi, so the way gbuild generates dependencies prevents ccache to be confident about using its cache most of the time. To see this: do a/ build b/ make clean c/build from an empty ccache dir once with and without dep-tracking.
The solution IMHO is to make gbuild run g++ twice, if building with deps and ccache: g++ -E $(DEP_GEN_OPTIONS) $(OTHER) foo.cxx && ccache g++ $(OTHER) foo.cxx The first will then only generate the deps without compiling, while the second one will compile and not confuse ccache. So: Are there volunteers for this to make the build quite a bit faster for devs? If not I will have to EasyHackify this ... Comments welcome.
