Re: Problems with building a Cross-Compiler

["Neil McCarthy" <nmccarthy at mail dot freenet dot co dot uk>]

Hi there,

I am having the same problem trying to produce a 2.95.1 sparc-sun-aout cross
compiler under solaris 7.

Please let me know if you get to the bottom of this as it is critical that I
get an aout compiler running on this machine alongside the elf format.

Thanks

Neil
