The Right Way to do this is to include all the subdir makefile fragments into one big happy make; then no special locking is needed. (A la "recursive make considered harmful".)
Boy, that's a big change, though. - Dan -----Original Message----- From: Harlan Stenn To: [EMAIL PROTECTED] Sent: 5/17/2002 5:41 PM Subject: Parallel builds and SUBDIRS First, I'm not saying this is a good idea. I'm working on a project where Somebody decided it would be a feature to hack the automake templates to permit subdirs to be built in parallel. They implemented an additional level of locking to prevent, for example, a library that is needed by multiple subdirs from being built simultaneously. I'm wondering if there is benefit to allowing SUBDIRS to be build in parallel by option (or default), and wondering if it's possible, reasonable, and not too difficult to use dependency lines in the "parent" Makefile.am to control serialization, ie: SUBDIRS = include lib bar baz foo lib: include bar baz foo: lib so that in a parallel build situation, we'd build include first, then lib, then bar, baz and foo in parallel.
