ninja process hanging forever when building esp32 arduino lib builder with component having ${CMAKE_BINARY_DIR} in INCLUDE_DIRS, idf_component_register (IDFGH-14412) #264

It's actually hanging while trying to collect all files for Arduino. Having that directive there is probably making it search through folders that is not prepared to go through and is running in circles. You can check the |

Is there anyway to control this behavior, such as excluding some folders for searching? Because some components could include build dir in INCLUDE_DIRS rather than PRIV_INCLUDE_DIRS, for example, micropython, micropython-ulab use INTERFACE library while building. It refers to runtime created header files inside build dir. So if including build dir (CMAKE_BINARY_DIR) in INCLUDE_DIRS, the whole build process could not finished. I waited for several hours but it is still there. |

The tooling here is tailored specifically for what Arduino needs. It extracts the files it also needs from the build dir (sdkconfig.h, bootloaders, etc), so maybe you need to be more specific than just adding the whole build dir to includes. |
|
Could you help me which codes, in which files, to search through include dirs to collect files for Arduino? I will modify the script to exclude build dir while collecting files but still existing when compile codes. Currently my compiling/linking is successful, but stuck at collecting files phase that you describe. |

I found it in file tools/copy-libs.sh, I will investigate it. |

I tried but ninja still hanging at phase " |
