• ffmpeg is failing to load shared libraries after a ./configure with a prefix inside a conda environment

  30 janvier 2024, par user3133806

  I am using conda and building ffmpeg from source within that environment.

  


  I ran the following commands :

  


  conda create --name my_conda_env
conda activate my_conda_env
# Now I am in the conda environment
# $CONDA_PREFIX is /home/myuser/.conda/envs/my_conda_env/bin/ffmpeg

# Checkout ffmpeg code
# git checkout ...

./configure --prefix=$CONDA_PREFIX --enable-shared --disable-static && make distclean && make -j 100 && make install

# The above command does install the newly built ffmpeg into:
# /home/myuser/.conda/envs/my_conda_env/bin/ffmpeg

# However it fails to execute:
ffmpeg
ffmpeg: error while loading shared libraries: libavdevice.so.58: cannot open shared object file: No such file or directory

# When I add the conda lib path to LD_LIBRARY_PATH it works:
LD_LIBRARY_PATH=$CONDA_PREFIX/lib:$LD_LIBRARY_PATH ffmpeg
ffmpeg version n4.2.9-4-gd7beb0c61f Copyright (c) 2000-2023 the FFmpeg developers

# I thought ./configure with a --prefix will build a binary that will search for libraries relative to itself, but that does not appear to be the case:

strace -o /tmp/strace.out ffmpeg
tail /tmp/strace.out

  Conda documentation says not to use LD_LIBRARY_PATH here :

  


  https://docs.conda.io/projects/conda-build/en/stable/resources/use-shared-libraries.html#shared-libraries-in-macos-and-linux

  


  How can I build ffmpeg from source in a conda environment and have the binary find the .so file relative to itself ?

  


• Anomalie #3974 (En cours) : bdd vide, si le choix du prefix des tables au moment de l’installation...

  15 juillet 2017, par Franck D

  Hello
  php 5.6.30 chez ovh en mutu
  Firefox 54.0.1

  Je viens de faire une installation d’un spip 3.2 (23671) pour test
  Si au moment de l’installation la personne fait le choix d’un préfixe avec des chiffres plutôt que des lettres, exemple : 320
  On arrive bien à l’étape 4, mais au moment ou l’on devrait partir dans l’espace privé après avoir cliqué, un message s’affiche "Attention : un problème technique (serveur SQL) empêche l’accès à cette partie du site. Merci de votre compréhension."
  Après, si je regarde dans la bdd avec phpmyadmin, il n’y a aucune tables
