• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sam Stephenson 2004-05-15 17:47:27 UTC]

I'm trying to install mono-0.91 on PPC.  I get the following error:

-mcpu=7450, -fsigned-char, -mstring, -mmultiple are all flags that are known to break code. Please try removing all of those flags and use only -mcpu=7400.

[Comment 2 Sam Stephenson 2004-05-15 18:54:38 UTC]

OK. I get the same error with CFLAGS="-mcpu 7400".

[Comment 3 Sam Stephenson 2004-05-16 03:22:11 UTC]

I upgraded to the latest gcc (3.2.3-r4) and glibc (2.3.3_pre20040420) and mono built cleanly.  Perhaps the dependency versions should be bumped?

[Comment 4 David Holm (RETIRED) 2004-05-16 03:29:43 UTC]

Ok, great, that saves me some time having to track down the problem. ;)
I will CC dotnet@g.o and let them decide how to update the dependency list.

[Comment 5 David Holm (RETIRED) 2004-06-02 13:56:50 UTC]

Updated the ebuilds of mono 0.91 and 0.95.
