How do I fix missing dependencies when installing FCEUX?

  • 772

I am attempting to install FCEUX from a .deb package that worked on Ubuntu 20.04 but does not install on 22.04.1 LTS.

I see the following errors:

Depends: libx264-155 but it is not installable
Depends: libx265-179 but it is not installable
E: Unable to correct problems, you have held broken packages.

Does this mean that 22.04 cannot use this package since it has these dependencies? Is there a way to install those older dependencies on 22.04?

The source is available but there aren't great instructions on building.

    fceux is actually in the Ubuntu repository. So you have two options, install the pre-built one or build from source.

    Install from Ubuntu

    sudo apt install fceux

    Build from source

    You can build this from source pretty easily. I just tested these instructions on Ubuntu 22.04 and 23.04, and it works.. see:

    FCEUX running Super Mario Bros

    Here's what you do:

    Install dependencies

    sudo apt update
sudo apt install git cmake build-essential qtbase5-dev pkg-config zlib1g-dev libminizip-dev libsdl2-dev liblua5.1-dev qttools5-dev libx264-dev libx265-dev libavcodec-dev libavformat-dev libavutil-dev libswscale-dev libswresample-dev cppcheck

    Get the source

    git clone https://github.com/TASEmulators/fceux
cd fceux

    Make the docs (optional)

    ./scripts/unix_make_docs.sh

    Build fceux

    mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
make

    Test it

    ./src/fceux

    It should launch as per my image above. If you're happy, you can "install" it.

    Install fceux

    sudo make install

    That'll put it all in /usr/local including the binary and all the other bits and bobs. It won't get updated of course, but if they update the source, you can always do the above again. Hope that helps.
