Re: Building universal binaries makes 'check' fail

[Elias Pipping]

seems to work!

== building ==

./configure \
             --prefix=/opt/local \
             --infodir=/opt/local/share/info \
             --mandir=/opt/local/share/man &&
make &&
make -k check >& ~/logs/autoconf-cvs.check.log; \
cp config.log ~/logs/autoconf-cvs.config.log

== files ==

autoconf-cvs.config.log.bz2
Description: Binary data

autoconf-cvs.check.log.bz2
Description: Binary data

Regards,

Elias Pipping
