Dear Help , Hi , I am trying to set up a fully working version of ffmpeg on my Linux Mint Qiana 17 OS , using thecomprehensive guide https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu . Please find attached a config.log complaining about a libass package not in the path . Also please see a second attached file pkg-configversion.txt showing releases data . I am an English old-age-pensioner and using Mint's Synaptic Package Manager I had Completely Removed ffmpeg version 7:2.4.3-1ubuntu1~trusty before following the guide . Any suggestions will be gratefully received and requests for more data will be acted upon . Thank you , Derek Hopley

This is the relevant error in config.log: pkg-config --exists --print-errors libass Package libass was not found in the pkg-config search path. This implies you have not installed libass-dev (or libass-devel). Carl Eugen
Dear Carl , Hi , thank you for your prompt reply , the package libass-dev is in my repository but simply following the https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu guide I can't see which step it is that actually 'loads' that libass-dev execution module into the configure process , 'once the penny drops' and I understand I should be able to add libass-dev and other missing modules should they also occur .

Hi , thank you for your prompt reply , the package libass-dev is in my repository
You have to install libass-dev. (Sorry, I don't use the same distribution as you so I am not sure how you can install it.) Once it is installed, the following typed on your command prompt will not show an error (as it does now): $ pkg-config --exists --print-errors libass Please find out what "top-posting" means and avoid it here.

Thank you ,
the same way as you install any other package on your distribution? and the same for all other missing dev-packages apt-get install libass-dev https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu clearly lists "libass-dev" as well as states the install command Get the Dependencies Copy and paste the whole code box for each step. First install the dependencies: sudo apt-get update sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev \ libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev \ libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev
