8. 8 gbuild -- Finishing the Beast gbuild: Hidden Gems
9. 9 gbuild -- Finishing the Beast Hidden Gems I didn't discover curves; I only uncovered them. Mae West make help make gb_COLOR=T make showdeliverables
10. 10 gbuild -- Finishing the Beast For Speedfreaks If programming languages were cars. C is a racing car that goes incredibly fast but breaks down every fifty miles. http://www.cs.caltech.edu/~mvanier/hacking/rants/cars.html make gb_CHECKOBJECTOWNER= make gb_FULLDEPS= make -j30 -l9
11. 11 gbuild -- Finishing the Beast gbuild: Quo Vadis?
12. 12 gbuild -- Finishing the Beast Kill set_soenv Insanity: doing the same thing over and over again and expecting different results. – Albert Einstein ./autogen.sh calls autoconf to generate ./configure, and calls it ./configure uses autotools to generate set_soenv and calls it ./set_soenv is a perl script that generates a shell script (toplevel) make calls bash and lets it parse the shell script before calling build.pl to start a build
13. 13 gbuild -- Finishing the Beast Kill Multiple Repository Support When accessorising, always take off the last thing you put on. Coco Chanel Multiple Repository Support is unused. Thus it is subject to bitrot ... … and already broken.
14. 14 gbuild -- Finishing the Beast Runnable Solver Simplicity is prerequisite for reliability. Edsger Dijkstra Make scp2 create output directly from workdir (or replace it from scratch) Make linkoo link directly to workdir only When replacing scp2, linkoo functionality should be part of the replacement
15. 15 gbuild -- Finishing the Beast Minor Cleanups If only for the sake of elegance, I try to remain morally pure. Marcel Proust Kill multilayer support once Libreoffice 4 API is around Use either $(eval $(call ..)) or $(call …) consistently Remove header copying
16. 16 gbuild -- Finishing the Beast Make gbuild the New Boss Meet the new boss Same as the old boss. The Who – Wont get fooled again Make gbuild the toplevel builder which triggers build.pl in the remaining modules Speedup Mostly implicit Dependencies Allows us to proceed with enabling advanced gbuild features
