Hi, After a couple of updates on my Gentoo systems (I'm a developer and I take care of automated testing, so I have a few installs around) I noticed that util-linux-ng takes an unexpected "long" time to build from scratch. The problem is that by using recursive make, it cannot run all of it in parallel (I have an 8-way system), as it synchronises on each directory. Also, the recursion itself is quite expensive for make to handle. I'm sending a series of patches that transform the build system from the current recursive Makefiles system to a non-recursive one. It's quite easy to deal with it, in general, you only have to remember that the target variables are prefixed with the relative path of the output (so it's misc_utils_blkid for instance, rather than simply blkid). I documented most of what is needed for non-recursive automake in my guide http://www.flameeyes.eu/autotools-mythbuster/ and if anybody have further doubts about it, feel free to drop me an email and I'll gladly extend the documentation. One thing that I have (yet) to document there is the handling of multiple .am files (module.am is what I called them) to avoid creating one huge Makefile.am file, and instead keep the rules tied with the sources themselves. Finally, I have wired out the testsuite to "make check"... it's mostly working although it fails for out-of-tree builds (and thus with make distcheck)... I can probably fix it but I wanted to make sure the rest is accepted first. I'll keep a git branch with these changes at http://gitorious.org/~flameeyes/util-linux-ng/nonrecursive-util-linux-ng to avoid having to fetch all the patches for those interested. P.S.: please do CC me on replies. -- HTH, Diego Elio Pettenò -- Flameeyes -- To unsubscribe from this list: send the line "unsubscribe util-linux-ng" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
