# pandemonium-cpp cmake arguments
|
|
# PANDEMONIUM_HEADERS_DIR: This is where the gdnative include folder is (pandemonium_source/modules/gdn/include)
|
|
# PANDEMONIUM_CUSTOM_API_FILE: This is if you have another path for the pandemonium_api.json
|
|
#

# ANDROID_NDK: The path to the android ndk root folder
|

# Examples
|
|
#
|
|
# Builds a debug version:
|
|
# cmake .
|
|
# cmake --build .
|
|
#
|
|
# Builds a release version with clang
|
|
# CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" .
|
|
# cmake --build .
|
|
#
|
|
# Builds an android armeabi-v7a debug version:
|
|
# cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake -DANDROID_NDK=$ANDROID_NDK \
|
|
# -DANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.9 -DANDROID_PLATFORM=android-23 -DCMAKE_BUILD_TYPE=Debug .
|
|
# cmake --build .
|
|
#
|
|
# Protip
|
|
# Generate the buildfiles in a sub directory to not clutter the root directory with build files:
|
|
# mkdir build && cd build && cmake -G "Unix Makefiles" .. && cmake --build .
|
|
#
|
|
# Todo
|
|
# Test build for Windows, Mac and mingw.
