Bug 142549 – qvamps-0.96 needs -fPIC on ~amd64

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description JTRiley 2006-08-02 08:41:22 UTC]

I'm running an unstable amd64 system and recently ran into a problem compiling qvamps-0.96.  The following error is given upon compiling which complains about the PIC flag needing to be set for compiling shared objects.  I have attached a patch to the Makefile and my modified ebuild that worked for me (just made a quick diff...).  This is a minor bug with a quick fix but I figured I'd help anyone else out and let the developers know as well.  Thanks!

Created attachment 93270 [details]
modified ebuild: qvamps-0.96.ebuild

This is my modified ebuild that fixed this compile error

[Comment 2 JTRiley 2006-08-02 08:44:14 UTC]

Created attachment 93271 [details, diff]
patch for ebuild posted above (qvamps-0.96)

This is the patch required by the above ebuild

[Comment 3 Tiago Sousa 2006-08-30 04:36:31 UTC]

Just to say this ebuild is working for me too.

[Comment 4 Stefan Briesenick (RETIRED) 2006-09-14 13:59:44 UTC]

I'm working on the new 0.98 release.

[Comment 5 Stefan Briesenick (RETIRED) 2006-09-14 15:27:57 UTC]

ok, new version in CVS. The -fPIC issue is solved there. But I will not fix the 0.96 version, because I want to remove it in a few days in favour to 0.98 which seems to work well and has some bug fixes.

New version 0.98 compiles just fine on my ~amd64 box.  Thanks for getting on this!
