[Solved] Trying to install OXCE V5.6.2 on Linux Mint?

[R1dO]

Just for some background.

It is expected that the following commands fail:

Code: [Select]

bash OpenXcomEx
bash OpenXcomEx.desktop
The reason is that "bash" expects to run script files. The first is a binary, the second is a file which tells your GUI how to run the associated binary.

The ".desktop" file is a (quickly written) workaround for a known bug in linux desktop environments dealing with some forms of binaries as created by modern "gcc", it is *NOT* a fault of  OXC(E).
The file is only necessary if you want to be able to run the program via double clicking from a file-manager application (shell as described by Meridian always work).

If you are trying to run OpenXcom Extended (V6.4.2) and get the following error when launching (From the terminal):

Code: [Select]

./OpenXcomEx: error while loading shared libraries: libSDL_image-1.2.so.0: cannot open shared object file: No such file or directory

Try installing the prerequisites you would need to compile OXCE (Information can be found: HERE )

Code: [Select]

apt install git cmake build-essential libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-gfx1.2-dev zlib1g-dev
Once those libraries are installed try to launch OpenXcomEx again, it worked for me so hopefully it will work for anyone else who gets stuck with that error message.
