Cross-compiling:
An example toolchain file for the CodeSourcery ARM toolchain is included in
the cmake directory: codesourcery-arm-toolchain.cmake.
Install the CodeSourcery toolchain, set the path to the toolchain in
cmake/codesourcery-arm-toolchain.cmake, and uncomment the TOOLCHAIN_FILE
variable in Makefile.cmake to use it.
If you are using cmake directly, just add the flag
"-DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain-file" when
running cmake.
Using cmake directly:
cd ~/your-node-source-dir
mkdir name-of-build-dir (can be anything)
