There were 2 errors. UAE may still build and run cleanly, but you may
not get all the features you asked for.

Patch to uae-0.8.22 file sysdeps.h

This patch checks the gcc version and if it is 3.4 or above, the REGPARAM2 macro is treated as is is on amiga, i.e. set to REGPARAM. This solved the problem for me.

I added a version check to only change behaviour for gcc 3.4 to change as little as possible, to make sure nothing breaks that worked before.
I notice however that the uae-0.8.24 sources just check for __GNUC__, without checks for AMIGA or gcc version. This would be an alternative, to backport the changes made in uae sources.

Do you have this problem with uae-0.8.24.ebuild?

> Do you have this problem with uae-0.8.24.ebuild?

As I mentioned, the 0.8.24 sources already set REGPARAM2 equal to REGPARAM, without regard for the gcc version. So the question is, will the uae 0.8.24 ebuild work with gcc 3.3.6 as well. I just checked, uae 0.8.24 compiles all right using either gcc 3.3.6 or 3.4.6.

The issue is solved in 0.8.24, marking it stable would be acceptable as well, instead of incorporating my patch into the uae 0.8.22 ebuild.
Comment 4 Jakub Moc (RETIRED) gentoo-dev 2006-10-28 17:36:39 UTC
No point in porting outdated stuff for gcc-3.4 when 4.1 is current stable on all arches this is keyworded for.

WONTFIX, see Bug 141217 for gcc-4.x porting.
