Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Initialisation de MediaSPIP (préconfiguration)
20 février 2010, parLors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.

How to fix the error "duplicate symbol _LOG_BUFFER_LENGTH"
25 mai 2019, par Florentin LupascuI have a Unity project embedded into Swift 4 and when I build the project I get an error from a plugin named FFmpeg (used to record the screen) and the error is next :

ld: 3 duplicate symbols for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)I want to specify that if I export the project from Unity to Xcode without to embed it is working perfectly with this Plugin.
What can be the problem with this error ?Until now I tried next thing to remove the error but none helped me :
- I checked if I have "-ObjC" in Xcode in "Other Linker Flags" and I don’t have.
- I removed a duplicate library (“libil2cpp.a”) from "Link Binary With Libraries" (XCODE)
- I changed ’No Common Blocks’ from Yes to No (under Targets->Build Settings->Apple LLVM - Code Generation )
At the end I have the same error.
Here is a print screen :
Thank you so much if you spend your time to read this and any idea will be helpful.
