To install the game, mount your CD & run the installer with linux32 from the util-linux package :
# mount /dev/cdrom /media/cdrom $ linux32 bash /media/cdrom/setup.sh
Apply the first patch :
$ linux32 bash kohan-1.2.0-x86.run
Apply the last released patch :
$ linux32 bash kohan-1.3.1-x86.run
Patch the binary to add a dependency on libX11.so.6 (required if you system SDL1.2 is in fact sdl12-compat)
cd <installation-directory> patchelf --add-needed libX11.so.6 ./kohan.dynamic
./kohan.dynamic greets you with “Segmentation fault”
This is due to a change in libgcc that broke some binaries that where compiled with gcc 2.95 in an unusual way (like compiling C++ code with gcc instead of g++).
You can use a little shim that add back functions required by a bunch of old games like this one.
LD_PRELOAD="/path/to/lokishim.so" ./kohan.dynamic
The missing function can be found in a very old libstdc++, and you can use libstdc++-3-libc6.2-2-2.10.0.so from https://www.improbability.net/loki/
LD_PRELOAD="./libstdc++-3-libc6.2-2-2.10.0.so" ./kohan.dynamic
