[Clfs-support] GCC-4.4.2 Cross Compiler final --with-float=soft

[Pascal Kesseli]

Hi forum

During the final spurt of my cross tool chain compilation - the compilation of the GCC-4.4.2 Cross Compiler final package - the following error message put a harsh end to my efforts:

the config.log in libgomp contains the following lines:

configure:2575: $? = 1

My uClibc is present in /mnt/clfs/lib, so where could this error emerge from?

Thanks a lot in advance for any suggestions on this one
Best regards
Pascal
