Summary

0005364: fontconfig compilations sometimes failed with parallel build

Description

fontconfig is affected by a compile bug that only occurs from time to time when parallel compilation is enabled. The bug is described at https://bugs.freedesktop.org/show_bug.cgi?id=16464. [^]

The attached patch includes the fix for fontconfig in buildroot. However, it modifies a Makefile.am file, so running automake is needed, but I'm not sure Buildroot will do that automatically (as the bug only occurs sometimes, it's quite hard to test whether the fix properly works or not).

Notes
(0013434) tpetazzoni 10-13-08 03:34	After testing, it seems that patching Makefile.am is not sufficient to re-run automake. What should be done in this case ? Provide a patch that also fixes the generated Makefile ? Run automake before compiling fontconfig ?

(0013894) tpetazzoni 10-20-08 08:02	It seems that the FOO_AUTORECONF option of Makefile.autotools.in was created for that kind of case. However, by reading the current Makefile.autotools.in code, I hardly see how FOO_AUTORECONF can do something: the AUTORECONF variable is not set: #AUTORECONF ?= autoreconf -v -i -f -I $(ACLOCAL_STAGING_DIR) How should this fontconfig building problem be fixed, until a new version of fontconfig is released with a fix ?
