cmake: use new signature form of target_link_library to link components !4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link components built under ESP-IDF build system. However, LINK_LIBRARIES does not produce behavior same as linking PRIVATE. This MR uses the new signature for target_link_libraries directly instead. This also moves setting dependencies during component registration rather than after all components have been processed. The consequence is that internally, components have to use the new signature form as well. This does not affect linking the components to external targets, such as with idf_as_lib example. This only affects linking additional libraries to ESP-IDF libraries outside component processing (after idf_build_process), which is not even possible for CMake<v3.13 as target_link_libraries is not valid for targets not created in current directory.

set(COMPONENT_REQUIRES app_update driver esp_event efuse pthread soc) #unfortunately rom/uart uses SOC registers directly
global: move the soc component out of the common list This MR removes the common dependency from every IDF components to the SOC component. Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components. But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components. In CMAKE, we have two kinds of header visibilities (set by include path visibility): (Assume component A --(depends on)--> B, B is the current component) 1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B) 2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only) and we have two kinds of depending ways: (Assume component A --(depends on)--> B --(depends on)--> C, B is the current component) 1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B) 2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B) 1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default. 2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it. 3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers 4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link) This is a breaking change. Previous code may depends on the long include chain. You may need to include the following headers for some files after this commit: - soc/soc.h - soc/soc_memory_layout.h - driver/gpio.h - esp_sleep.h The major broken include chain includes: 1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h. 2. ets_sys.h no longer includes soc/soc.h 3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h BREAKING CHANGE

esp32: Component needs public dependency on tcpip_adapter Because of esp_event.h Closes https://github.com/espressif/esp-idf/issues/1954
2018-05-16 23:55:40 -04:00
# driver is a public requirement because esp_sleep.h uses gpio_num_t & touch_pad_t
esp32: Add firmware version to app Added a new structure esp_app_desc_t. It has info about firmware: version, secure_version, project_name, time/date build and IDF version. Added the ability to add a custom structure with a description of the firmware. The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t. app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe). Add API to get app_desc from partition.

esp32: Rename esp32.common.ld to esp32.project.ld to avoid build errors when downgrading Linker script generator produces build/esp32/esp32.common.ld from components/esp32/ld/esp32.common.ld.in This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and doesn't track build/esp32/esp32.common.ld at all. At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the linker script generated .ld file, which causes mis-builds.
