flatpak: cabextract workaround #27
Description
I stumbled upon a game that has gold reports on protondb, but requires protontricks modifications. Therefore I followed the steps in the wiki to get that set up. I came across the same problems as in #25, but that has since been solved. Then, the problem was that cabextract was missing.
The wiki states that the flatpak version of steam does not include some libraries used by winetricks.
Workaround
The solution I found was adding it manually:
Compile latest
git clone https://github.com/kyz/libmspack.git
cd libmspack/cabextract
./autogen.sh
/usr/local/bin is read-only inside the flatpak, adding the prefix becomes necessary
./configure --prefix=$HOME/.local
gcc (requirement) is not present in the flatpak, the compilation needs to be made outside
make
Install it inside the flatpak
cd ..
mv cabextract $HOME/.var/app/com.valvesoftware.Steam
flatpak run --command=bash com.valvesoftware.Steam
cd cabextract
make install
exit
Add path to PATH as env
The last step is to add the binary located in .local/bin to the command. As it is the same location as the protontricks binary, the path to it is no longer necessary, changing the alias in the .bashrc file to:
alias protontricks-flat='flatpak run --env=WINETRICKS=$HOME/winetricks --env=STEAM_RUNTIME=0 --env=PATH=$PATH:$HOME/.local/bin --command=protontricks com.valvesoftware.Steam'
I suppose adding other libraries would be similar, but I haven't had the need yet.
@Matoking I dunno if you want this in the wiki or not, as its kinda specific to cabextract and might be clutter for people that don't require it.
Either way, if someone comes looking for an answer, I hope this points them in the right direction!
