What helps me with this is using ccache (compiler cache) - it keeps the compile results inside a cache and when compiling the same file again it fetches the result from there. on debian it is just: apt-get install ccache export PATH=/usr/lib/ccache:$PATH ...work on kernel like normal... c'ya sven -- The lights are fading out, once more... -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
