[SOLVED] Re: Problems building cross-compiler on Sparc Solaris 8for x86 Solaris 10... (cont.)

[Aaron Gaudio <agaudio at eng dot mc dot xerox dot com>]

I'd like to report success in my endeavor, however I did have to do some
tinkering with some make/configure scripts... my patch is attached
below. Note that I didn't alter configure.in because I didn't feel like
running autoconf over the tree. Make of it what you will, but this patch
allowed me to build gcc 3.4.3 with C and C++ for Solaris 10 x86 with a
Solaris 8 Sparc as host, using --with-sysroot instead of --with-libs/--
with-headers. 

To those who wrote in, thanks for your help with this.
