[vlc-devel] Cross-compiling for Win32 on Ubuntu x86_64 fails

[Jarrad Whitaker]

Winning! After some playing with Dependency Walker, it looks like the contribs were being shared-linked against libwinpthread-1.dll instead of statically. Copying /usr/x86_64-w64-mingw32/lib/libwinpthread-1.dll to the VLC bin dir on Windows has things running nicely.
Should I raise a bug for this? I would hazard that either this should be part of the install process, or contribs should be linked statically.
