Windows cross-compilation problem with Qt4

Hi everybody,

I am currently trying to compile VLC player for Windows on a Ubuntu 14.04 virtual machine for development of a new audio filter module. Cross-compilation already worked with VLC 2.1.0, but buildling the latest 3.0.0-git fails with the same setup (even without my new module).
I followed the instructions on https://wiki.videolan.org/Win32Compile/ which works fine, until I try to run the configure shell script (last before the last step), which strangely cannot be found (although it exists). Using the propsed alternative "../configure --host=..." works but produces some errors related to x265 and taglib. So I disable them and use:

Code: Select all

../configure --host=i686-w64-mingw32 --disable-x265 --disable-taglib

This works. However, when I run "make" I get the following error after about 10 minutes (posting the last couple of lines here):

Code: Select all

libqt4_plugin.la does not exist anywhere in the vlc folder. As a workaround, I already tried copying it from an older project (VLC 2.1.0) and the associated dll's as well, but this didn't help either (compiler got a few steps further then exited with a similar error message).
I assume it is some kind of mess-up between Qt4 and Qt5, because libQt5core.a seems to try to call something related to Qt4. And the Qt5-related-steps before the error seem to work fine.

I have already done a lot of research etc. but without any success. Could someone please advise me how to resolve this issue?

Thanks a lot and best regards,
Wolfgang

Hi Wolfgang,

I have come to the similar issue recently. In my case it was enough to rebuild qt4 contribs. To do that, you need to go to vlc/contrib/win32 and run

Code: Select all

make .qt

there.

Hope this helps
