downloadpkgsrc-398497eafbb59ef231b748969db71a474a8f4aee.tar.gz
Add experimental support for -j jobs building in the build
target. MAKE_JOBS is undefined by default. You can test this by setting in mk.conf: MAKE_JOBS=5 for example. Some package just won't build correctly with this -- these individual packages can set MAKE_JOBS_SAFE=no to disable it. This is based on discussion from last December 2005. Some pkgsrc users are using ideas like this. Note I have been using this since December 2005 on various single processor and multiprocessor systems. (Once I kept some stats on performance but have misplaced that now.) I haved tested this with many packages (but not a bulk build) on Linux, NetBSD and DragonFly. This commit doesn't include the commits for the MAKE_JOB_SAFE. As this is experimental it needs more testing. Some examples of problems are: comms/lrzsz, databases/gramps2, editors/vim, graphics/MesaLib, graphics/netpbm, net/bind9, print/ghostscript-esp, textproc/libxml, and www/lynx.
