This looks rather similar to http://bugs.gentoo.org/show_bug.cgi?id=101627
the first thing i tried was USE="-pic" and then no ldflags and less cflags.
(In reply to comment #2) > the first thing i tried was USE="-pic" and then no ldflags and less cflags. as Spanky said, don't mess with the use flags/cflags/ldflags, that had been an error on my part.
(In reply to comment #2) > the first thing i tried was USE="-pic" and then no ldflags and less cflags. what are you talking about? xzgv doesn't have a pic USE flag...
due to no response, marking this WORKSFORME

repoening now. seems to be a problem only for hardened toolchain.
I can confirm this bug using hardened.
Commenting out the CFLAGS+=-DINTERP_MMX of course lets this pkg compile. The logic used in the ebuild is incorrect also. It assumes that any x86 cpu is mmx aware. --- xzgv-0.8-r2.ebuild 2006-04-10 14:36:21.000000000 +0000 +++ xzgv-0.8-r3.ebuild 2006-04-21 08:29:19.000000000 +0000 @@ -11,7 +11,7 @@ LICENSE="GPL-2" SLOT="0" KEYWORDS="alpha amd64 ~hppa ia64 ppc ~ppc64 sparc x86" -IUSE="" +IUSE="mmx" DEPEND="media-libs/libpng media-libs/jpeg @@ -26,7 +26,7 @@ cd ${S} cp config.mk config.mk.orig sed -i -e "s:-O2 -Wall:${CFLAGS}:" config.mk - + use mmx || sed -i -e "s:-DINTERP_MMX::" config.mk case "${ARCH}" in "x86") ;;
Taking into account, that the last release from upstream was done in september 2003 it seems unlikely, that the author will actually fix his code in a way compatible to mmx and PIE (if it is even possible). Or does anybody know if it still maintained by the author? I also assume neither maintainer nor hardened team have time and motivation for that. Therefore following solar's suggestion seems the best solution to me. Maybe the ebuild may additionally warn not to use "mmx" on a hardened system/PIE-enabled gcc?
upstream is indeed dead afaict
Created attachment 85423 [details, diff] Makes xzgv compatible with the gentoo hardened profile (ie: PIC)
Comment on attachment 85423 [details, diff] Makes xzgv compatible with the gentoo hardened profile (ie: PIC) This is actually a problem in libmmx, which hasn't been updated since 1999 it would appear. The site that it was originally hosted on is no longer up. Fortunatelly the code is distributed with xzgv, so it's an easy patch. I added this patch to a local ebuild and re-emerged and it compiles fine with the hardened profile. Hope that helps.
Sounds great. I also put it into my local ebuild. ;-) Nonetheless Solars patch should be added too, for being able to disable mmx by USE flag if one doesn't want to use it or the CPU does not support it.
no more xzgv, but I'm open for gtk+-2.0 alternatives we don't have yet.
