OK, I just found out about this tool and called "ccache" I wanted to share my enthusiasm with somebody. Basically, it keeps a cache of previous invocations of gcc and makes re-compilation INSANELY faster. What I did on my Debian work box is <bash> configure CC='ccache gcc' --enable-quiet-build --enable-build-addons \ --with-odbc --enable-build-editor --disable-xdg time make -j6 make clean time make -j6 </bash> First make: real 0m42.887s user 3m46.995s sys 0m27.083s Second make: real 0m9.971s user 0m48.332s sys 0m10.464s I found out about ccache on a stackoverflow page. Guess who the tip is from?
