export CMAKE_EXPORT_COMPILE_COMMANDS=1
Before compiling

Hi @Shipley1105

You can output the compile commands during the SCons build by appending export_compile_commands=1 build/compile_commands.json to your build command.

For example:
scons arch=armv8a os=linux neon=1 export_compile_commands=1 build/compile_commands.json

You also need to have SCons >= 4.0 installed and available in your environment.
