vlc installed but not opening when clicked in ubuntu 1404

Solution 1:

this error can happen when a you compile a library and do the install yet the freshly installed library is not yet registered to the system ... if that is the case just issue this

sudo ldconfig 

then vlc will find the library and launch OK

when compiling c++ projects from source, like vlc, this is necessary to register the dynamic libraries ... after the sudo make install

I am on ubuntu 18.04 installing vlc 4.0 from source

Solution 2:

Open a terminal (Ctrl+Alt+T) and run :

sudo apt-get install libvlc5 

If it's already installed, you may also need to link your local libraries to the system libraries :

sudo ln -s /usr/local/lib/libvlc* /usr/lib/
sudo ln -s /usr/local/lib/libx264.a /usr/lib/
sudo ln -s /usr/local/lib/vlc /usr/lib/vlc
