gcc build fails "cannot compute suffix of object files"

[Joel Sherrill]

Hi,

First if you updated to RHEL5, you could just use the prebuilt RPMs.


Second, dou are using binutils from the wrong place.
After it is installed, you should have /opt/rtems/bin in your PATH
based upon what I see in the log. The directory configure
found ranlib is in NOT for public use.

checking for arm-rtems4.10-ranlib...
/opt/rtems/rtems-4.10//arm-rtems4.10/bin/ranlib

Since these tools don't have the target in front of the tool
base name, gcc is probably confusing native and cross in horrible
ways.
