I dont have very much more to say ... never used it, wanted to try it, no clue
what should happen ... but is obviously "abnormal".

> Lot to compile before gdbing.
Sure, thanks for your effort. I will look into it when you send us a backtrace.
Denis.

shall I also recompile =dev-libs/glib-2.12.9 and libgtk+ ? (according to strace
glib-1.2 should be the bugging part)
seems to be due to the fact that it links with gthread 1.2, I grepper my kino
emerge logs and found only links to gthread 2 and found the offending line in
your emerge log :
-lgthread
Now we have to figure why it wants to link with gthread 1 ;)
(btw you forgot the "bt full" part in your previous post, which is the
interesting part ;) )
could you please post the output you get from :
pkg-config --cflags libquicktime
pkg-config --libs libquicktime
I think that libquicktime forces kino to link to gthread 1.

These are the packages that would be merged, in order:

just ask ^^

Which to me looks pretty much like strace's output ...
Note that at a time, I thought it was a problem with my locale being
en_GB.ISO-8859-15 ... so, I do tests in a console where locale is C.
got that here :
$ pkg-config --libs libquicktime
-lquicktime -lpthread -lm -lz -ldl
while looking at your emerge log :
checking for library containing pthread_create... -lgthread
while for me it finds pthread, which seems more sane ;)
Could please attach libquicktime config.log ?
(In reply to comment #12)
cf comment #10 ? :D
ldd says both kino and libquicktime are linked to libgthread-1.2.so.0 and
libpthread.so.0
Kino is also additionnally linked to libgthread-2.0.so.0
want compleet outputs ?
yep libquicktime tries in its configure checks to look for pthread_create in
gthread 1. I dunno if it's really wrong, but you're the first person I see that
has it :)
Anyway, I've uploaded a hack :
http://dev.gentoo.org/~aballier/kino-0.9.5-gthreads.patch
could you try it ?
could you also post the output of emerge -pv =dev-libs/glib-yourglib1.2-version
?
Denis any thoughts about this ? It should be sane also to remove gthread from
libquicktime to prevent those kind of bugs, but as it's a lib I'd prefer to
keep in sync with upstream.

Calculating dependencies... done!
[ebuild R ] dev-libs/glib-1.2.10-r5 USE="-hardened" 0 kB
Total: 1 package (1 reinstall), Size of downloads: 0 kB
add this line at the end of src unpack :
epatch "${FILESDIR}/${P}-gthreads.patch"
and add :
inherit eutils
at the top of the ebuild
(note that if you don't copy the modified ebuild and the patch it will be lost
at the next emerge --sync )
Patch proposed at comments #14 and #17 allowed me to build a runnable program.
Waiting for merge, then I ll close.
Can you also test exporting/importing a quicktime video ?
If quicktime is compiled against gthread 1 and kino gives him gthread 2, this
will segfault also, and thus libquicktime will need to be fixed rather than
kino.
not how to export to this format. Exporting to 3GPP worked (using ffmpeg)
exporting to dv using dv quicktime should use libquicktime, for example in the
terminal output I get :
quicktime_encode_video_stub called
quicktime_delete_vcodec_stub called
which are from libquicktime.
The fix looks rather harmless to me, so I have just committed it to cvs. I've
used the following sed statement instead of Alexis' patch, but it does the same
thing:
sed -i \
-e '/\$(LIBQUICKTIME_LIBS) \\/d' \
-e '/^[[:space:]]*\$(SRC_LIBS)/ a\
\$(LIBQUICKTIME_LIBS) \\' \
src/Makefile.in
Thanks Benoît-Pierre for your bug report, and thanks Alexis for your solution.
Denis.
