[GEM-dev] compilation with msys2 on w64

[Patrice Colet]

Hello,

I'm attempting to add a ffmpeg film plugin with a windows 64 machine...

First I'd like to thank umläute about this wiki page: 
https://github.com/umlaeute/Gem/wiki/How-to-build-Gem-on-Microsoft-Windows-(MINGW) 


It seems mingw packages has some improvements since this howto has been 
written...

$ pacman -Ss ftgl
mingw32/mingw-w64-i686-ftgl 2.4.0-1 [installé]
     OpenGL library to use arbitrary fonts (mingw-w64)

Unfortunately 'mingw64/mingw-w64-x86_64-ffmpeg' package doesn't provide 
a working version of ffmpeg yet, so

I'm trying out with mingw32...

Anyway in both version I'm trying to get VLC plugin working first with 
mingw VLC packages, in mingw64 the VLC plugin loads during pd starting, 
but is disabled when [pix_video] is loaded. I don't why it is disabled...

And in mingw32 the VLC plugin doesn't load at pd starting because runDLL 
don't find some vlc libs.

  After installing Gem, I go to pd/extra folder and add all the 
depencies with this bash script:

#!/bin/bash
echo "Looking in mingw for DLL dependencies"
for GEM_DLL in $(ls *.dll)
do
     echo "looking into" $GEM_DLL
     for DLL in $(ntldd -R $GEM_DLL)
     do
         if [[ $DLL == *mingw* ]]; then
             for DLL_DEP in $(ntldd -R $DLL)
             do
                 if [[ $DLL_DEP == *mingw* ]]; then
                     FILE=Gem/$(basename $DLL_DEP)
                     if [ ! -f "$FILE" ]; then
                         echo "copying:" $DLL_DEP
                         cp $(cygpath -u $DLL_DEP) Gem
                     fi
                 fi
             done
             FILE=Gem/$(basename $DLL)
             if [ ! -f "$FILE" ]; then
                 cp $(cygpath -u $DLL) Gem
                 echo "copying" $DLL
             fi
         fi
     done
done

FFMPEG and VLC dependencies seems to be added to along Gem.dll but 
runDLL couldn't find modules at pd starting, while other libs like 
libassimp3 or libjpeg or libtiff are loaded.

I'm probably missing something somewhere...

Do I need to compile VLC and FFMPEG to get them working in pd?
