nil out CurrentHedgehog in FreeModule, add a test for nil'd CurrentHedgehog in DelCI since I'd still like to use DeleteGear for the other stuff it does. Move some variable initialiasations in AI Misc to hopefully avoid some uninit val errors.
To compile and install you need: - CMake >= 2.6.0 - FreePascal >= 2.2.4 - Qt >= 4.7.0 - SDL >= 1.2.5 - SDL_net >= 1.2.5 - SDL_mixer >= 1.2 - SDL_image >= 1.2 - SDL_ttf >= 2.0 - Lua = 5.1.0 - Physfs >= 2.0.0For server: - Glasgow Haskell Compiler >= 6.10 - bytestring-show package - dataenc package - hslogger packageFor videorecording: - FFmpeg or LibAV - GLUT (when SDL < 2)For compressed screenshots: - libpngLua will be automatically built if not found.PhysFS will internally built unless -DPHYSFS_SYSTEM=on is passed to cmake(also allows to set PHYSFS_LIBRARY and PHYSFS_INCLUDE_DIR if needed).1. Configure:$ cmake .or$ cmake -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX="install_prefix" \-DDATA_INSTALL_DIR="data_dir" -DNOSERVER=1 .Add -DNOSERVER=0 to compile net server (remember to check out the additionaldependencies with the hedgewars-server.cabal configuration file. If you haveQt installed but it is not found, you can set it up with-DQT_QMAKE_EXECUTABLE="path_to_qmake".To get a glimpse of the main configuration options, you may use this command`cat CMakeLists.txt | grep option`2. Compile:$ make3. Install:# make installThat's all! Enjoy!
