py3exiv2 installation sous windows

**lcrprod** · 13/05/2019, 10h24

Bonjour,

je ne trouve pas dans la doc comment faire l'installation de cette lib sous windows.

Avez vous une idée de comment faire? car la je ne vois pas du tout.

Merci par avance.

je ne trouve pas dans la doc comment faire l'installation de cette lib sous windows.

Avant de pouvoir l'installer, il faut faire le build (compiler, linker).
Ce qui peut être galère car adapter un logiciel développé pour Linux sur Windows n'est jamais simple.... et les savoir faire n'ont rien à voir avec la programmation Python.
Donc sauf à trouver un mode d'emploi sur Internet, vous avez au moins deux solutions:

installer une machine virtuelle Linux sur Windows,
voir si une bibliothèques équivalente ne suffirait pas à vos besoins (genre piexif.

Merci pour la nouvelle piste.

je vais creuser car, je pense qu'effectivement, elle devrait me suffire pour ce que j'ai besoin de faire sur mes fichiers raw.

Salut,

Un utilisateur l'a compilé pour window, voici ce qu'il m'a envoyé. (pas encore testé)

Here’s what I did:

The key part in making this work is https://github.com/Microsoft/vcpkg, it has both exiv2 and boost-python.

[INSTALLING PYEXIV3 ON WINDOWS]
- install GIT-2.21.0-64-bit.exe
- install VSCodeUserSetup-x64-1.33.1.exe
- clone vcpkg, note the folder name
$ git clone https://github.com/Microsoft/vcpkg.git
- install vcpkg by running .\bootstrap-vcpkg.bat
- run vcpkg.exe install boost-python:x64-windows
- run vcpkg.exe install exiv2:x64-windows
- make sure to add /installed/x64-windows/bin to the PATH (for dll import)
- get the pyexiv2 sources from here: http://py3exiv2.tuxfamily.org/downloads
- replace setup.py with my version
- set the environment variable VCPKG to the folder where you installed it
- run pip install -e <py3exiv2-folder>

I’ve attached my modified version of setup.py. It’s very rough since I don’t know much about setuptools at all, but it essentially involves bypassing `get_libboost_name` which fails completely on windows and using the environment variable VCPGK that has to be set by the user to point at the vcpkg directory. There’s probably a cleaner way of doing this, like accepting a command line argument. But again, I have no idea how setuptools handles this so hopefully you can clean it up a bit. `boost_python37-vc140-mt` is also completely hardcoded, you’d probably have to modify `get_libboost_name` to work on Windows.

While I’m at this, I’ve noticed the lack of support for custom xmp tags. For now I’ve resorted to abusing various IPTC Tags for my purpose, but that’s a rather terrible solution. I’d appreciate it if you could prioritize adding that feature in the future.

with best regards,

Vic

et bien après une petite adaptation j'ai réussi à faire le traitement.

il faut que je teste maintenant cette nouvelle version sur linux, mais cela devrais roulez comme sur des roulettes.

Merci beaucoup pour cette petite trouvaille.

**VinsS** · 13/05/2019, 17h37

Pour Linux c'est distribué en paquets .deb, .rpm, c'est sur le dépôt de la communauté Archlinux et, si cela ne suffit pas, encore sur PyPI.

Rien à compiler normalement.

Bonjour,

Pour lire les informations "exif" des fichiers image, j'utilise pour ma part l'exécutable "exiftool", parce qu'il donne beaucoup d'informations, y compris celles qui sont spécifiques aux marques d'appareils photo:
=> https://www.sno.phy.queensu.ca/~phil/exiftool/

Il est multiplateforme. Il est prévu pour la console, mais on peut l'utiliser à partir de Python comme je l'ai dit ici avec un exemple de code Python:
=> https://www.developpez.net/forums/d1...mage-exiftool/.
