[vlc-devel] vlc3 : cannot link with libaccess_srt_plugin

[Justin Kim]

Hello,

The linking error is pretty strange for me.

Did you set PKG_CONFIG_LIBDIR to a proper pkgconfig directory?
Maybe, in your case, 
/usr/lib/pkgages/BUILD/vlc-3.0.0/contrib/x86_64-suse-linux/lib/pkgconfig ?

SRT plugin has dependencies on gnutls, nettle
