It look like there is a cross dependence, the build of tcsh failed with the following message: /var/tmp/rpm-tmp.7250: /usr/bin/perl: No such file or directory error: Bad exit status from /var/tmp/rpm-tmp.7250 (%build) So tcsh is needed to build perl and perl is needed to build tcsh :-( > > > > > I also would like to do a cross build, but how do I do that ? > > Do I have to change all the spec files, to set the target arch to MIPS, or is > > there a easier and better way to do that ? > > I guess if I just install the SRPMs and the cross toolchain, and try to build > > out of that I will simply build for the build platform, which is i386. > > You need my patched `rpm' to do cross build.
