Description Michael Rowell 2013-09-08 21:48:32 UTC 
Installing libgphoto2-2.5.2 and media-gfx/gphoto2-2.5.2 and running

gphoto2 --auto-detect

fails to detect any cameras using a PTP interface. Applications dependent on libgphoto2 are also affected. Running 

gphoto2 --auto-detect --debug

produces the error "0.023098 gphoto2-abilities-list(2): Failed to load '/usr/lib64/libgphoto2/2.5.2/ptp2': file not found."

Downgrading to arch-stable versions (libgphoto2-2.4.14-r1 and gphoto-2.4.14) resolves the issue.

Please paste the output of emerge -pv libgphoto2 and qlist libgphoto2 (from portage-utils). Thanks.

Comment 3 Alexandre Rostovtsev (RETIRED) gentoo-dev 2013-09-10 14:27:28 UTC 
Thanks. So /usr/lib64/libgphoto2/2.5.2/ptp2.{la,so} are installed on your system, but gphoto2 doesn't see them for some reason.

Please attach the complete "gphoto2 --auto-detect --debug" output, maybe there is a useful error message in it.

gphoto2 auto-detect debug output
Comment 5 Alexandre Rostovtsev (RETIRED) gentoo-dev 2013-09-10 20:39:09 UTC 
Thanks. Unfortunately, the debug output didn't help with diagnosing the problem.

Another possibility, maybe the /usr/lib64/libgphoto2/2.5.2/ptp2.la file is invalid for some reason. Could you attach it please?

Comment 7 Alexandre Rostovtsev (RETIRED) gentoo-dev 2013-09-11 02:36:56 UTC 
.la file looks fine.

Another possibility: libgphoto2 plugins compiled using lto are confusing libltdl's loader somehow. Try setting conservative CFLAGS/CXXFLAGS/LDFLAGS in your make.conf (so CFLAGS="-march=corei7-avx -O2 -pipe", LDFLAGS="-Wl,-O1 -Wl,--as-needed").
Then rebuild sys-devel/libtool, media-libs/libgphoto2, and media-gfx/gphoto2, and see if the problem persists.

Sorry, compiled libtool, libgphoto2 and gphoto2 with

CFLAGS="-march=corei7-avx -O2 -pipe -fno-lto"
CXXFLAGS="-march=corei7-avx -O2 -pipe -fno-lto"
LDFLAGS="-Wl,-O1 -Wl,--as-needed -fno-lto"

Issue persists.

I am out of ideas, and nobody on the gnome team has been able to reproduce this :/

@base-system, any suggestions why lt_dlopenext("/usr/lib64/libgphoto2/2.5.2/ptp2") would be failing with FILE_NOT_FOUND?

No problem, I guess I'll just stick with stable for now.

Honestly, that's what my experience with Gentoo always seems to be. Every time I install and use it, eventually something weird breaks in a way no one else seems to experience, and it's never a serious bug that crashes the desktop or anything, always something small.

LD_DEBUG=all gphoto2 --auto-detect --debug, grep'd for ptp2
Comment 12 Michael Rowell 2013-11-22 03:01:49 UTC 
UPDATE: Alright, so I have a shiny new Nikon D5200 sitting in front of me, and it's convinced me to try to fix this thing. I read that setting LD_DEBUG=all and running gphoto2 would give lots of library-related debug. Well, LOTS is the word. 8M log file. I grep'd for ptp2 and attached the result.

2.5.2, no LTO, ggdb symbols and support for all cameras compiled. Ran 'LD_DEBUG=all gphoto2 --auto-detect --debug &> gphoto2.log' with no cameras attached. 'cat gphoto2 | grep ptp2 > ptp2.log' Here's what I found:

First mention of ptp2:
0.048508 gphoto2-abilities-list(2): Found '/usr/lib64/libgphoto2/2.5.2/ptp2'.
     16272:     file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0];  dynamically loaded by /usr/lib64/libltdl.so.7 [0]
     16272:     file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0];  generating link map

Then a whole bunch of GLIBC version checking, then some "relocation processing", some symbol lookup information. Binding /usr/lib64/libgphoto2/2.5.2/ptp2.so to /lib64/libc.so.6, individual symbols at a time is what it looks like. And then this little gem:

16272:     symbol=olympus_setup;  lookup in file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0]
     16272:     /usr/lib64/libgphoto2/2.5.2/ptp2.so: error: symbol lookup error: undefined symbol: olympus_setup (fatal)
     16272:     file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0];  destroying link map
     16272:     file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0];  dynamically loaded by /usr/lib64/libltdl.so.7 [0]
     16272:     file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0];  generating link map

After which the output is the same as before. So it does this a few times (trying again, I suppose), before we get to:

     16272:     symbol=olympus_setup;  lookup in file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0]
     16272:     /usr/lib64/libgphoto2/2.5.2/ptp2.so: error: symbol lookup error: undefined symbol: olympus_setup (fatal)
     16272:     file=/usr/lib64/libgphoto2/2.5.2/ptp2.so [0];  destroying link map
0.113037 gphoto2-abilities-list(2): Failed to load '/usr/lib64/libgphoto2/2.5.2/ptp2': file not found.

So by my interpretation gphoto2 tried and tried and failed on this symbol.

While I'm researching this issue, perhaps someone with more knowledge of what we're dealing with could chime in and either point me in the right direction or else correct any errors in my understanding? Much appreciated.
Comment 13 Evgeny Bobkin 2013-11-22 10:25:35 UTC 
Can you please try to build libgphoto2 with the two patches included in this bug report, maybe they are related to this report as well, because of the libxml2 linkage where ptp is also involved.

Seems to fix it. My PTP cameras are autodetected just fine now, no errors in 'gphoto2 --auto-detect --debug'. Well then.

Thank you very much. Looks like I'm good to go.
