Bug 90763 – media-libs/libpano12 version bump (2.7.0.10), working on amd64

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Bernard Cafarelli 2005-04-28 13:40:45 UTC]

This is a follow-up to bug #87451:
media-libs/libpano12 works OK on amd64, if optimisation is set to -O0 in CFLAGS. With higher optimisation, the program will segfault when run.

Using patch-o-matic and something like "replace-flags -O? -O0" in src_compile do the job for an ~amd64 ebuild

Tested optimisations are: -O1 or -O2 -fno-strict-aliasing but both produce segfaults when running the program.

This behavior has been noted on the hugin mailing list by amd64 users

Reproducible: Always
Steps to Reproduce:
1. emerge libpano12 on amd64 with -O1 or other
2. run PTOptimizer
3. get a segfault
4. reemerge with -O0
5. PTOptimizer runs fine

libpano12-2.7.0.10.ebuild

Version 2.7.0.10 fixes this problem.  Here is an ebuild for the new version.  I
have installed this on my machine with optimization set to -O2 and it worked
and seemed to run faster than previous versions.  2.7.0.8 and 2.7.0.9 both
would seg fault with optimization set to -O2 on my amd64 machine.

[Comment 2 Bernard Cafarelli 2005-05-19 11:29:36 UTC]

Too bad I cannot test it (getting segfaults everywhere with hugin 0.5rc1, I'm
looking at why...)

The changelog does indicate many 64bit updates in the last version:

libpano12-2.7.0.10.ebuild slightly modified

Only slightly modified.

[Comment 4 Bernard Cafarelli 2005-06-12 06:28:00 UTC]

I can confirm now that 2.7.0.10 works with optimization enabled here (I could
test it using an updated snapshot of hugin which solved my problem)

I changed the bugreport name to reflect the latest comments

[Comment 5 Simon Stelling (RETIRED) 2005-07-13 08:37:12 UTC]

i don't know why this ebuild request got assigned to amd64@g.o...

lu_zero: looks like you're the maintainer of libpano12. if so, please put
yourself into metadata.xml

[Comment 6 Mark Loeser (RETIRED) 2005-08-10 17:09:06 UTC]

New version is in the tree.
