Matt, I just wanted to say thanks for capturing in a nutshell the argument for a Meson trial. I want Meson because my builds are too slow. I regularly build an entire fucking operating system from scratch (Chrome OS), and I cry when top shows only 1 core at 100% and the other 47 cores sitting idle. Autotools and libtool are often the culprit. The libtool penalty is paid on every build, not just at configure time. The only way to get all 48 cores closer to 100% is to (1) use a non-recursive build system that (2) doesnt' use shell nor (3) libtool. I don't care about new shiny. I'm often wary of new shiny things that receive too much excitement. Meson is a such a new shiny. But I'm willing to overlook my aversion to new shiny Meson's immaturity if it makes Chrome OS build faster... at least for Mesa. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
