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++.
+Also included are some simple utilities for KMS and python bindings for libkms++.
+
+## Utilities
+
+- testpat - set modes and planes and show test pattern on crtcs/planes
+- kmsprint - print information about DRM objects
+- kmsview - view raw images
+- db - simple double-buffering test
+- kmscube - rotating 3D cube on crtcs/planes
+- kmscapture - show captured frames from a camera on screen
## Dependencies:
- libdrm
-- SWIG 3.x (for python & lua bindings)
- Python 3.x (for python bindings)
-- Lua 5.x (for lua bindings)
## Build instructions:
+To build the Python bindings you need to set up the git-submodule for pybind11:
+
+```
+git submodule update --init
+```
+
+And to compile:
+
```
$ mkdir build
$ cd build
## Cross compiling instructions:
-Directions for cross compiling depend on your environment. These are for mine (buildroot):
+Directions for cross compiling depend on your environment.
-As above, but specify `-DCMAKE_TOOLCHAIN_FILE=<path>/your-toolchain.cmake` for cmake, where your-toolchain.cmake is something similar to:
+These are for mine with buildroot:
```
-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 ${BROOT}/host)
-
-SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM ONLY)
-SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
-SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
+$ mkdir build
+$ cd build
+$ cmake -DCMAKE_TOOLCHAIN_FILE=<buildrootpath>/output/host/usr/share/buildroot/toolchainfile.cmake ..
+$ make -j4
```
## 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
+Option name | Values | Default | Notes
+--------------------- | ------------- | -------- | --------
+CMAKE_BUILD_TYPE | Release/Debug | Release |
+LIBKMS_ENABLE_PYTHON | ON/OFF | ON |
+LIBKMS_ENABLE_KMSCUBE | ON/OFF | OFF |
