    Re: Linking BSEC library to ESP-IDF for BME680

    Hello! I managed to fix the issue. I separated the BME680 files from the BSEC files. My BSEC component structure is as follows:

    • include (folder)
    1. bsec_datatypes.h
    2. bsec_integration.h
    3. bsec_interface.h
    • lib (folder)
    1. libalgobsec.h (normal)
    • bsec_integration.c
    • CMakeLists.txt
    • component.mk

    The CMakeLists.txt contains:

    CODE: SELECT ALL

    set(COMPONENT_SRCS 
    "bsec_integration.c")
    
    set(COMPONENT_ADD_INCLUDEDIRS include)
    set(COMPONENT_REQUIRES "BME680")
    register_component()
    target_link_libraries(${COMPONENT_TARGET} "-L${CMAKE_CURRENT_LIST_DIR}/lib")
    target_link_libraries(${COMPONENT_TARGET} algobsec)

    The component.mk contains:

    CODE: SELECT ALL

    COMPONENT_SRCDIRS := .
    COMPONENT_ADD_INCLUDEDIRS := include
    
    LIBS := algobsec
    
    COMPONENT_ADD_LDFLAGS     := -lbt -L $(COMPONENT_PATH)/lib \
                               $(addprefix -l,$(LIBS))
    ALL_LIB_FILES := $(patsubst %,$(COMPONENT_PATH)/lib/lib%.a,$(LIBS))
    COMPONENT_ADD_LINKER_DEPS := $(ALL_LIB_FILES)
    COMPONENT_SUBMODULES += lib

    My BME680 component structure is as follows:

    • include (folder)
    1. bme680.h
    2. bme680_defs.h
    3. bme680_platforms.h
    4. bme680_types.h
    • bme680.c
    • bme680_platform.c
    • CMakeLists.txt
    • component.mk

    The CMakeLists.txt contains:

    CODE: SELECT ALL

    set(COMPONENT_SRCS "bme680_platform.c"
                       "bme680.c")
    set(COMPONENT_ADD_INCLUDEDIRS "include")
    
    register_component()

    The component.mk contains:

    CODE: SELECT ALL

    COMPONENT_ADD_INCLUDEDIRS := include
