Linking BME680 BSE2C library to ESP-IDF and PlatformIO

[kotyara12]

Good day!

Help to connect an external compiled library libalgobsec.a to the ESP-IDF and PlatformIO project (maybe this is essential).
I created a driver library with the following structure (maybe this is wrong):



I tried to do it by analogy with viewtopic.php?f=13&t=12633&p=50373&hilit=bsec#p50373, unfortunately it did not help. CMake is a dark forest for me.

CMakeLists.txt:

Code: Select all

set(COMPONENT_ADD_INCLUDEDIRS inc)

register_component()
target_link_libraries(${COMPONENT_TARGET} "-L${CMAKE_CURRENT_LIST_DIR}/esp32")
target_link_libraries(${COMPONENT_TARGET} algobsec)

component.mk:

Code: Select all

COMPONENT_SRCDIRS := .
COMPONENT_ADD_INCLUDEDIRS := inc

LIBS := algobsec

COMPONENT_ADD_LDFLAGS     := -lbt -L $(COMPONENT_PATH)/esp32 \
                           $(addprefix -l,$(LIBS))
ALL_LIB_FILES := $(patsubst %,$(COMPONENT_PATH)/esp32/lib%.a,$(LIBS))
COMPONENT_ADD_LINKER_DEPS := $(ALL_LIB_FILES)
COMPONENT_SUBMODULES += esp32

Unfortunately it doesn't work.... What am I doing wrong?

Code: Select all
