It's patch for a source code of OSI library and I have repository with applied patch.
https://github.com/JOndra91/OISYou can download built library from my
google drive and just place it into <rwr_install_dir>/lib, replacing the original library bundled with game.
Alternatively if you know how to build stuff and you don't want to use prebuilt library from some random guy on the internet just clone repository and then run following commands in repository directory:
Code:
./boostrap
# I suppose that you are on 64bit system
./configure --build=i686-pc-linux-gnu "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"
make
If everything goes well just replace <rwr_install_dir>/lib/libOIS-1.3.0.so with <ois_repo>/src/.libs/libOIS-1.4.0.so. It has to be renamed as libOIS-1.3.0.so.
Also, let me know if it works for you. It has been built on debian and tested on arch, so there should be some distro crosscompatibility.
