Sudden problem with compiled gphoto applications not running. Error Loading a Library

richbai90 commented 2 years ago

Describe the bug

Not really a bug but I don't know where to get support specifically for libgphoto2. If I am in the wrong place, please direct me to the correct one.

I am faced with the sudden inability to run a program compiled with libgphoto2. The build succeeds without any errors, but reports Error Loading a Library This happens with code that was working previously, and even example code from the repo. It started after I attempted to compile the library from source with debug flags so I could step through and understand the internals of the library better. Even after removing the library and reinstalling the version from the package manager ( apt : libgphoto2-dev/stable ) I am faced with the same error. Telling is the fact that if I run print-camera-list idlist I get an empty response. I think for some reason the camera libraries aren't linked correctly to the main library, but that's just my hunch

Name the camera Camera is not detected by gphoto2 either, which only just started happening with this same issue. lsusb reports that the camera is connected.

libgphoto2 and gphoto2 version

This version of gphoto2 is using the following software versions and options:
gphoto2         2.5.27         gcc, popt(m), exif, cdk, aa, jpeg, readline
libgphoto2      2.5.29.1       NON-STANDARD CAMLIB SET (adc65 agfa_cl20 aox ax203 barbie canon casio_qv clicksmart310 digigr8 digita dimagev dimera3500 directory enigma13 fuji gsmart300 hp215 iclick jamcam jd11 jl2005a jl2005c kodak_dc120 kodak_dc210 kodak_dc240 kodak_dc3200 kodak_ez200 konica konica_qm150 largan lg_gsm mars mustek panasonic_coolshot panasonic_dc1000 panasonic_dc1580 panasonic_l859 pccam300 pccam600 pentax polaroid_pdc320 polaroid_pdc640 polaroid_pdc700 ptp2 ricoh ricoh_g3 samsung sierra sipix_blink sipix_blink2 sipix_web2 smal sonix sony_dscf1 sony_dscf55 soundvision spca50x sq905 st2205 stv0674 stv0680 sx330z template topfield toshiba_pdrm11 tp6801 SKIPPING docupen lumix), gcc, no ltdl, EXIF

I tried compiling all supported camera libraries to see if this would correct the issue. It did not.

To Reproduce Not sure, but try first by compiling from source and removing the installed libraries via the package manager, and then any remaining instances by hand (find / | grep libgphoto | xargs -I {} sudo rm -rf {})

When reproducing with the commandline tool, attach debugout using --debug --debug-logfile=debug.log if considered useful.

I'm not a gphoto dev, just some general ideas. See if libs are fine using ldd /usr/local/bin/gphoto2. Also, running ldconfig may help.

Thanks for the advice, it looks like the libraries are all properly loaded though. The output from ldd shows:

Running ldconfig doesn't seem to change anything either.

Okay I got it fixed. Here's what I did:

su  # run as root

# Remove all traces of libgphoto2 on the system
apt remove libgphoto2-dev
apt purge libgphoto2-dev
find / | grep libgphoto | xargs -I {} rm -rf {}
apt install libgphoto2-dev --reinstall
#  Notice the following warnings
# dpkg: warning: files list file for package 'libgphoto2-l10n' missing; assuming package has no files currently installed
# dpkg: warning: files list file for package 'libgphoto2-6:armhf' missing; assuming package has no files currently installed
# dpkg: warning: files list file for package 'libgphoto2-port12:armhf' missing; assuming package has no files currently installed

# install missing packages
apt install libgphoto2-l10n libgphoto2-6 libgphoto2-port12

# Test if it's working
gphoto2 --auto-detect

# what do ya know?

@richbai90 is this supposed to erase your main partition or what? 😅

richbai90 commented 2 years ago

Lol! Yeah I guess so 😬. I fixed it in case someone opts to copy/paste without checking first lol. Thanks for the catch.

I have two questions:

What operating system ist that? It ships a separate libgphoto2-port12 package, and I am interested about that.
Have you compiled a newer libgphoto2 source, and installed it by just overwriting the files the operating system package ships with?

I haven't tried just straight overwriting, I used the configure prefix option with make install.

Well, building and installing libgphoto2 with configure --prefix=/usr && make && sudo make install is straight overwriting, and would explain your above gphoto2 --version output showing 2.5.27 for gphoto2, 2.5.29.1 for libgphoto2, and 0.12.1 for libgphoto2_port.

Just trying to understand what (might have) happened.
