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.

Compiling FFMpeg libraries for Visual Studio
20 janvier 2015, par LostBoyI’m trying to use the FFMpeg libraries in a Windows application. I use MingW-w64 to compile FFMpeg with static libraries with architecture once with x86 and once with x86_64.
Currently I’m trying to link the 32bit x86 libraries with my VS2008 application.
The libraries are added to the library path and VS does not complain about being unable to load a .a file.However I get several uneresolved symbol errors like
ait_rtp_receiver.lib(ait_decoder_lib.obj) : error LNK2001 : unresolved external symbol _av_freeI import the FFMpeg header files as extern C and I can see the symbols in the .a without the leading underscore.
What can I do to make the name decoration of Mingw-w64’s gcc and of the VS compiler suite compatible ? -
Linking libavformat in Visual Studio 2010
30 octobre 2012, par slavik262I'm attempting to build some video-reading code around libavformat. After getting the compiled DLLs and
.lib
files here, I go to build my code, and the linker can't find any of the libavformat symbols even though I've linked in the provided.lib
files.Inspecting
libavformat.lib
withdumpbin -headers
reveals that it exports the desired functions with an underscore prefix. For example, while I want to callavformat_open_input
, the .lib file gives_avformat_open_input
.Why is this, and why can't I link the precompiled dlls ?
