Subject: race between aclocal and unstaging of .m4 files
Date: Mon, 29 Oct 2012 14:42:28 +0000 [thread overview]
Message-ID: <1351521750.13864.12.camel@phil-desktop> (raw)
If do_configure() from one recipe runs in parallel with
sysroot_cleansstate() from another then aclocal may fail because it
doesn't react very well to .m4 files disappearing underneath it. This
manifests as slightly obscure failures such as:
| aclocal: error: aclocal: file '.../tmp-eglibc/sysroots/x86_64-linux/share/aclocal/alsa.m4' does not exist
where the .m4 file in question is not one that the recipe being built
would actually want to use. (The alsa.m4 error above actually occurred
during a build of attr.)
There seem to be two obvious ways of fixing this:
a) Add more locking so that these things can't happen in parallel
b) Patch aclocal to make this situation non-fatal
My inclination would be to do (b) since it's less intrusive. Any
objections or better suggestions?
