GCC 4.7 build problems

GCC 4.7 build problems

[Vincent Diepeveen]

hi,

GCC 4.7.0 is a big step forward! Really a quantumleap.

Works great at opensuse 11.3, both i386 and x64 here at AMD64 and  
intel Xeon i386 install.

Fails to build at OpenSuse 11.2 as well as Scientific Linux 6.2 x64

hardware: dual socket Xeon L5420 in both cases.

Build error:

"configure: error: cannot compute suffix of object files: cannot  
compile"

Exactly at same spot the same error like at opensuse 11.2

The building at Scientific Linux 6.2 x64 is pretty important - it's  
the same distro basically like RHEL 6.2
SL 6.2 runs a cluster for me. Performance there is crucial.

Anyone knows a way how to get it to work there?
Is this the correct list to report build errors?

Thanks in Advance,
Vincent

No, please send any follow-up to gcc-help@gcc.gnu.org only.
