Re: [OpenBIOS] Compiling Openbios with Sparc cross compiler

[Paul Wilhelm]

I tried installing openSUSE 12.1 from scratch (since that is working for
Andreas). I grabbed all tools except binutils and gcc from SUSE packages. I
used the configure scripts you kindly provided, Andreas, for binutils and
for gcc. I get the same error with openSUSE as I did with Arch. Have I
overlooked an environment variable that needs to be set? I am just using
fresh install stuff with no special environment set by me.

Here is the error output and the gcc -v output.

I also tried the configure you gave shortly ago, Blue, for gcc and get the
same error.

Respectfully,
Paul.
