===== Game crash =====
''./descent3.dynamic'' greets you with //"SIGNAL 11 caught, aborting"// 

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" ./descent3.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" ./descent3.dynamic</code>
