Does it search the paths in a different order? > pkgconfig-native searches its own built in path (the one in the native sysroot) along with the paths in PKG_CONFIG_PATH. None of those are outside of the sysroots.

If that's not happening here, that's a bug that should be investigated, but I fail to see how setting PKG_CONFIG is going to magically fix it. -- Christopher Larson clarson at kergoth dot com Founder - BitBake, OpenEmbedded, OpenZaurus Maintainer - Tslib Senior Software Engineer, Mentor Graphics _______________________________________________ Openembedded-devel mailing list [email protected] http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-devel
