[Buildroot] [PATCH] vlc: fix build when Qt4 development files are installed on the host

[Yann E. MORIN]

Thomas, All,

On 2014-10-08 23:11 +0200, Thomas Petazzoni spake thusly:
> When Qt4 development files are installed on the host, VLC uses
> /usr/bin/moc, /usr/bin/uic and /usr/bin/rcc when Qt support is
> enabled. However, those host installed versions are not necessarily
> compatible with the Qt version used in Buildroot, causes some build
> failures.
> 
> This commit therefore passes explicit ac_cv_path_MOC, ac_cv_path_RCC
> and ac_cv_path_UIC variables to make sure the Qt host tools built by
> Buildroot are used.
> 
> Note that the VLC configure.ac script uses 'pkg-config
> --variable=exec_prefix QtCore' to find the location of such tools, but
> this invocation returns /usr. One solution would have been to extend
> the pkgconf-01-fix-variable.patch we have against pkgconf to also
> cover exec_prefix, but this has more uncertain consequences than just
> fixing VLC.
