Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Raspberry crosscompilation in Eclipse
27 juin 2018, par gogoerI want to compile an application for Raspberry in Eclipse (in windows). I installed SysGCC, configured Eclipse for crosscompiling. And if I create something like "Hello world" - everything is ok. Eclipse creates binaries which wonderfully works on Raspberry.
But i need use FFMPEG libraries in my application . Here the minimal code of application :#include <libavcodec></libavcodec>avcodec.h>
#include <libavformat></libavformat>avformat.h>
#include <libswscale></libswscale>swscale.h>
int main(void) {
av_register_all();
return EXIT_SUCCESS;
}I added libraries in project config. Project compiles good, but linker gives a lot of errors :
C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\local\lib\libavcodec.a(aaccoder.o): In function `quantize_and_encode_band_cost_template':

collect2.exe: error: ld returned 1 exit status
make: *** [ffmpeg] Error 1
02:21:24 Build Finished (took 8s.394ms)SOLVED :
i used next command :
arm-linux-gnueabihf-gcc -L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\local\lib" -L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\lib" -o "ffmpeg" ./src/ffmpeg.o -lc -lm -lpthread -lavformat -lavcodec -lswscale -lavutil -lavfilter -lavdevice -lswresample -lpostproc -ldl -lx264 -lgcc -lz
where -lc -lm -lpthread -lavformat -lavcodec -lswscale -lavutil -lavfilter -lavdevice -lswresample -lpostproc -ldl -lx264 -lgcc -lz are libraries linker needs (maybe not all of them).
please note that order is important.
