Win32Compile in Ubuntu/Debian

[masticover]

Hello everyone,

The cross-compilation of VLC in Ubuntu/Debian is being really frustrating and discouraging. Let's me explain.

Following the guide from https://wiki.videolan.org/Win32Compile/:

Ubuntu 14.04 is too old to compile VLC

...

Ok, I will use Ubuntu 16.04.

After installing Mingw-w64 toolchain, development tools, cloning the repository, prebuild the 3rd party libraries, etc. Let's configure (https://wiki.videolan.org/Win32Compile#Configure)

Error, Mingw > 5.0 needed! Ubuntu 16.04 installs Mingw-w64 version 4...

Ok, after uninstall the current version of Mingw and install Mingw 5.3, when configuring the project again:

Code: Select all

configure: error: You need 32-bits luac when using using lua from contrib.

OMG! I have installed lua (following the guide

apt-get install lua5.2

)

Ok, lets go and disable lua (--disable-lua) and get rid of this.

Code: Select all

configure: error: libavutil versions 55 and later are not supported.

Both, in Ubuntu 16.04 and Debian 9, for VLC 2.x.

Let's try vlc-3.0 (https://github.com/videolan/vlc-3.0)

Code: Select all

configure: error: You need 32-bits luac when using using lua from contrib.

Ok, sh**t, I will disable lua for this one too:

../extras/package/win32/configure.sh --host=i686-w64-mingw32 --build=x86_64-pc-linux-gnu --disable-lua

Code: Select all

configure: error: cannot find FAAD library

No kidding!

# ../extras/package/win32/configure.sh --host=i686-w64-mingw32 --build=x86_64-pc-linux-gnu --disable-lua --disable-faad

Configuration Ok! Ou yeah! Let's compile:

Code: Select all

fatal: Not a git repository: '../../extras/package/win32/../../../.git/' cat: ../../extras/package/win32/../../../src/revision.txt: No such file or directory Makefile:3241: recipe for target 'stamp-revision' failed Makefile:1522: recipe for target 'all-recursive' failed Makefile:1407: recipe for target 'all' failed make: *** [all] Error 2

Wait! I will try to configure it manually: ../configure --host=i686-w64-mingw32 --build=x86_64-pc-linux-gnu --disable-lua --disable-faad

Code: Select all

Configuration finished ok! Well, let's compile: fatal: Not a git repository: '../../.git/' cat: ../../src/revision.txt: No such file or directory

Could someone help me with this? I just want to compile VLC for Windows 32 bits. And I don't know what else to do. Is there any other tutorial or something I could follow to get this work?

Thanks folks!

Just use our docker image for that. Or run extras/package/win32/build.sh -a i686 on the 3.0 branch.

Hi,

Thanks for the answer Jean-Baptiste.

1. With the docker image, trying to build the container (in "vlc-debian-win32" folder):
docker build -t vlc_win32 .

This gives me the following error (after almost an hour of compilation):

2. Running extras/package/win32/build.sh -a i686 on the 3.0 branch (after one hour or so of compilation too):

Code: Select all

I'm using a VM (VirtualBox) Debian 9 Stretch for the compilation. Don't know what else to do...

Thanks again for your help. I'm planning to develop an addon for VLC and I hope this step won't take me too much time

[masticover]

Hi,

Finally, I managed to compile VLC on the 3.0 branch, as follow:

1. Cloning 3.0.0 branch.
2. Modifying files "rules.mak" in vlc/contrib/src/d3d9 and vlc/contrib/src/d3d11: change "wine" to "wine-development" inside them.
3. Execute build scritp: ./extras/package/win32/build.sh -a i686

The problem now, after creating an Out of tree module as stream filter, is that VLC does NOT found my plugin, giving me the following message when launching it:

Code: Select all

... main debug: recursively browsing `C:\Users\myuser\Documents\vlc-3.0.0\plugins' main warning: cannot load module `C:\Users\myuser\Documents\vlc-3.0.0\plugins\stream_filter\libmydemofilter_plugin.dll' (No se puede encontrar el módulo especificado. (error 126)) main debug: plug-ins loaded: 488 modules ...

I'm using CMake, the plugin es properly compiled, but VLC does't recognize it. Any help?

Thanks.

[masticover]

This is really weird :S

Creating a sample Out of tree module, Vlc loads it if it's created in one file, but not if it uses another file/library. I mean:

- Vlc loads the module if I have a single file:
mydemofilter_plugin.cpp

- Vlc does NOT load the module if I use a function from another library/file:
mydemofilter_plugin.cpp
|---> utils.cpp

What is really strange here is that if I include the header (#include utils.h in mydemo_plugin.cpp) the module is loaded, but when I use a function from utils.h, Vlc does NOT found my module, giving me the error:
... main debug: recursively browsing `C:\Users\myuser\Documents\vlc-3.0.0\plugins' main warning: cannot load module `C:\Users\myuser\Documents\vlc-3.0.0\plugins\stream_filter\libmydemofilter_plugin.dll' (No se puede encontrar el módulo especificado. (error 126)) main debug: plug-ins loaded: 488 modules ...

Does anyone know what might be happening? :/

Thanks.

Win32 LoadLibrary() cannot load your module.

[masticover]

Hi Rémi,

Yes, we both agree about that

The question is why Vlc (ie, Win32 LoadLibrary()) does not load the module when using a dummy function from a dummy class?

For example, here is the code of the class Utils:
Utils.h

#include <cstdio>
#include <string>
#include <stdlib.h>

bool checkLoad();


Utils.cpp

#include "Utils.h"

bool checkLoad()
{
return true;
}


That's all. If I only include this class in my demo module, the compilation is Ok and Vlc (ie, Win32 LoadLibrary()) load the module perfectly.
If I call "checkLoad()", the compilation is Ok but the module is not loaded.

But what could be the problem? This is driving me crazy :/

[masticover]

Any help here?

Thanks.

[Rémi Denis-Courmont]

VLC does not load because the Win32 run-time loader does not load.
