hi all again, i have also tried with latest trunk, but same error. I found an old discussion where Rene and Lars said: "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).
