This source shows how to use CMake to build the tutorial executables on various OS environments.

The executables can be buildable in various situation with help of CMake.

It is tested in the following environments

- Linux native
- Cross compile on ubuntu 14.04
- Windows 7

In order to cross compile this package, you need to prepare your own root file system by copying the target root file system into your host system. Check below steps.

1. clone this source

   cd ~
   git clone https://github.com/seetime/SDL_tests.git
   cd <source_dir>
   

2. prepare your custom root file system

   For example, assume it is located at /<your_rootfilesystem>

3. Modify a toolchain script at

   vim cmakemodule/Toolchain_bpi_arm.cmake

   or

   vim cmakemodule/Toolchain_bpi_armhf.cmake

   Find CMAKE_FIND_ROOT_PATH and modify it to point to your custom root file system location and save it.

4. Create the Makefiles by running

   cd ~/<source_dir>
   mkdir build_crosscompile
   cd build_crosscompile
   cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmakemodule/Toolchain_bpi_armhf.cmake
   make
   

5. Find all executables in ~/bin-xxxxxx folder

In this way, I was able to run the binaries built out of crosscompiling on the target machine. If you share the source tree as nfs with

the target machine and build it in both side of host machine and target machine, then you can see this.
