It seems a bit lame for paths to be restricted to such a short length. How does a 192-byte TMPDIR end up causing more than 131072 bytes of arguments and environment? Can anything be done to reduce that? For example, can you use "gcc @..." to remove common options from the command line? Can you eliminate garbage from the environment that doesn't need to be there? p. _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
