I'm using Fedora Core 5, and it disliked GDC (as it's using GCC 4.1!)

But using GCC 3.2 (compat) as the compiler and GCC 4.0 as the basis,
I was able to bootstrap a working "opt" version of GDC there as well...

As a tip, you should probably be building in another directory... ?
You can set a new top directory up with macros, for a non-admin user.

Yes, you can't actually use them if you have GCC/G++ installed :-)
Just figured I might as well package them, since it builds it anyway.

It is, but it needs to match the system C/C++ compiler *perfectly*...
I'm doing this on Mac, but for the RPM spec I did both that and "opt"

Idea being that any "system" version of GDC would install under /usr,
but if you need a full GCC/G++ to match it - they all go in /opt/gdc ?


I posted some thoughts on this very topic earlier, in:
http://www.digitalmars.com/d/archives/D/gnu/1561.html

I believe the "integration" problems should be rather similar,
whether on Fedora Core or on Mac OS X ? (both patch their GCC)
