Re: Build T2 on Ubuntu 7.10

Maybe we should merge the disabling the perl cross build for default  
builds
as it is too error prone. In trunk we already do not cross build perl  
by default
anymore (despite that the perl 5.10 perl has new, major cross build  
regressions,
anyway).

Oh, I just see this change is already in 7.0. Can it be the case that  
you
are building a slightly older 7.0 release tarball? Can you re-try with  
the
branches/7.0 from SVN?

Lars: I had to revert that $CC change as that broke building T2 on T2!  
The
reason is that this $CC is used for configure checks, and when the cross
compiler is used the configure is usually completely messed up.

The best way to probably fix correctly cross building perl is to not  
write the
perl config from the T2 package selection and C library feature set as
opposed to let this perl supplied script check all this out (most test
try to run the resulting binary anyway, which is not suitable while
cross building anyway, despite if you would run the resulting executable
on the target hardware or an emulator - both not to appealing way that,
for example, scratch box is offering).

Yours,
