Generated sources location not under src

I’m using extraScript to generate some sources before build.

All works fine if I’m putting all generated sources inside src/ dir.

Actually, it is better to place for generated sources is inside build dir:

build_path = env.GetBuildPath("$BUILD_DIR")
generated_src_dir = os.path.join(build_path, 'mylib', 'generated')

All include headers, located in generated from this example can be seen by the project. Main problem is that .c/.cpp files not compiled in this case.

I tried to add them with SRC_FILTER but failed (seems because it accepts only relative paths):


So, how to add generated sources located inside build directory to the project?

So, can somebody tell me, is it possible to place generated sources outside src folder?

Exactly, the path here is relative the src_dir.

I’m not sure if it’s possible what you want to do, adding source files from the build output directory in the build system. You can also open issue at Issues · platformio/platformio-core · GitHub for clarification.

I found another solution to add custom sources dir:

build_path = env.subst("$BUILD_DIR")
generated_src_dir = os.path.join(build_path, 'mylib', 'generated')
generated_build_dir = os.path.join(build_path, 'mylib', 'generated', 'build')
env.BuildSources(generated_build_dir, generated_src_dir)

This works.


Interesting. I’ve opened Add example with env.BuildSources() · Issue #209 · platformio/platformio-docs · GitHub to have that added to the documentation.
