====== Kohan: Immortal Sovereigns ======

===== Install & patch the game =====

To install the game, mount your CD & run the installer with ''linux32'' from the ''util-linux'' package :
<code>
# mount /dev/cdrom /media/cdrom
$ linux32 bash /media/cdrom/setup.sh
</code>

Apply the first [[https://ftp.lokigames.twolife.be/pub/updates/kohan/kohan-1.2.0-x86.run|patch]] :
<code>
$ linux32 bash kohan-1.2.0-x86.run
</code>

Apply the last released [[https://ftp.lokigames.twolife.be/pub/updates/kohan/kohan-1.3.1-x86.run|patch]] :
<code>
$ linux32 bash kohan-1.3.1-x86.run
</code>

Patch the binary to add a dependency on libX11.so.6 (required if you system SDL1.2 is in fact [[https://github.com/libsdl-org/sdl12-compat/|sdl12-compat]])
<code>
cd <installation-directory>
patchelf --add-needed libX11.so.6 ./kohan.dynamic
</code>


===== Game crash =====
''./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++'').

==== Option a ====
You can use a little [[https://github.com/twolife/lokishim|shim]] that add back functions required by a bunch of old games like this one. 

<code>LD_PRELOAD="/path/to/lokishim.so" ./kohan.dynamic</code>

==== Option b ====
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/loki_compat_libs-1.5.tar.bz2|https://www.improbability.net/loki/]]

<code>LD_PRELOAD="./libstdc++-3-libc6.2-2-2.10.0.so" ./kohan.dynamic</code>
