# libkms++ - C++ library for kernel mode setting
libkms++ is a C++11 library for kernel mode setting.
Also included are simple test tools for KMS and python and lua wrappers for libkms++.
## Dependencies:
- libdrm
- SWIG 3.x (for python & lua bindings)
- Python 3.x (for python bindings)
- Lua 5.x (for lua bindings)
## Build instructions:
```
$ mkdir build
$ cd build
$ cmake ..
$ make -j4
```
## Cross compiling instructions:
Directions for cross compiling depend on your environment. These are for mine (buildroot):
As above, but specify `-DCMAKE_TOOLCHAIN_FILE=<path>/your-toolchain.cmake` for cmake, where your-toolchain.cmake is something similar to:
```
SET(CMAKE_SYSTEM_NAME Linux)
SET(BROOT "<buildroot>/output/")
# specify the cross compiler
SET(CMAKE_C_COMPILER ${BROOT}/host/usr/bin/arm-buildroot-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER ${BROOT}/host/usr/bin/arm-buildroot-linux-gnueabihf-g++)
# where is the target environment
SET(CMAKE_FIND_ROOT_PATH ${BROOT}/target ${BROOT}/host)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
```
## Build options
You can use the following cmake flags to control the build. Use `-DFLAG=VALUE` to set them.
Option name | Values | Default
-------------------- | ------------- | --------
CMAKE_BUILD_TYPE | Release/Debug | Release
LIBKMS_ENABLE_PYTHON | ON/OFF | ON
LIBKMS_ENABLE_LUA | ON/OFF | ON
|
