Just wanted to write a thank you post for everyone who's worked on getting OpenApoc to it's current working state. Being able to play OpenXcom (UFO + TFTD) and OpenApoc without the limitations of DOSBOX, etc is a wonderful thing. I'm not a Linux expert by any stretch but I thought I'd expand on the installation instructions listed on the github page. First I grabbed the latest files from github into my home directory using: git clone --recurse-submodules -j8 https://github.com/OpenApoc/OpenApoc.git Then I downloaded the latest Apocalypse installer from GOG (setup_xcom_apocalypse_18.104.22.168.exe) Rather than installing the game through Wine you can use innoextract to get the required game files. Make a directory, copy the GOG installer into it and run: innoextract setup_xcom_apocalypse_22.214.171.124.exe You should end up with two new folders (app + tmp) plus the GOG installer. Navigate to the app/CD folder. There's a handy tool called bchunk that we can use to convert the GOG bin/cue image into an ISO image. Simply run: bchunk XCOM.BIN XCOM.cue cd mv cd01.iso cd.iso Copy cd.iso into the data subfolder where the cloned code from github resides. Then proceed with the instructions on the main github page i.e. mkdir build cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo .. (I used Release instead) make -j4 ./build/bin/OpenApoc As you can see the game is working perfectly. If anyone's curious about the overlay in the screenshots, I've set the following line in my .xinitrc: export GALLIUM_HUD=simple,fps,cpu,GPU-load,temperature A nice feature that comes with mesa drivers.
