Re: installing a cross compiler

After reading the following, it sounds like you want a cross gcc that
runs on a Linux/386 host, and targets a solaris2.7 system.

Right.  The gcc 2.96 you are referring to is a "native" compiler.  It
produces executables for the host machine.

This is probably ok, but I STRONGLY discourage your using /usr as your
prefix.  It's all too easy to screw things up when working as the root
user.  Instead, work as a normal user, and use a prefix that you have
permission to write to (a subdirectory of your home directory, for
example).

Nope, this won't work.  As your error messages indicate, you're
missing a lot of header files.  See the FAQ at
http://crossgcc.billgatliff.com instead.

Note that to complete the procedure, you'll probably need a runtime
library as well.  The FAQ is currently underdocumented where glibc is
concerned, but when my new Sun Blade workstation arrives (this week!),
I'll look into it.  Suggestions from others are welcome.


HTH,
