• BXT_LOGFILE - if set, logs all Bunnymod XT messages into a file with that filename.
• SPTLIB_DEBUG - if set to 1, logs all dlopen, dlclose and dlsym calls.

Building

Windows

• Get Boost and build chrono, date_time, system and thread.
• Get and build Detours.
• Create a build directory along the src directory.
• Run cmake -DBOOST_ROOT=path\to\boost\base\dir -DDetours_ROOT=path\to\detours\base\dir .. from the build directory.
• Compile the ALL_BUILD project from the generated VS solution.

Linux

• You will need 32-bit Boost libraries chrono, date_time, system and thread.
• Create a build directory along the src directory.
• Run cmake .. from the build directory. You might need to specify -DBOOST_ROOT=path/to/boost/base/dir if you're running a 64-bit linux and have built the 32-bit Boost libraries separately.
• Run make from the build directory.
