Also, what we have seen in the other thread it is codetools that causes it.
Maybe that can be disabled in a Lazarus build for your PowerPC?
Codetools has many more bugs. (mostly because it lags behind features, not usually on endianness)
I concluded you have a working FPC - because the lazarus build process uses it - and a broken Lazarus because of codetools failing to compile.
And, indeed, as wp wrote, stick to a single thread for the same subject.
