unable to compile after porting rosserial to idf v4.x #2

Closed VedantParanjape closed 4 years ago

VedantParanjape commented 4 years ago

I added a CMakeLists.txt to rossserial_esp32 component to make it compatible with idf.py

My CMakeLists.txt content:

idf_component_register(SRCS "duration.cpp"
                            "time.cpp"
                            "esp_ros_wifi.c"
                    INCLUDE_DIRS "include"
                    REQUIRES vfs nvs_flash)

my code: https://github.com/VedantParanjape/ROS-Workshop-ESP32-Codes

You will need to add a CMakeLists.txt file inside the main folder of your project (https://github.com/VedantParanjape/ROS-Workshop-ESP32-Codes/tree/master/codes/ROS_with_servo_control/main).

main folder is treated as a component and hence it requires its own CMakeLists.txt. Since there is no CMakeLists.txt inside the main folder, the build system excludes it and hence could not find reference to app_main

It compiles ! Thanks !

Getting some issues with linker while binary generation.

VedantParanjape commented 4 years ago

Update: deleting the build folder and recompiling fixed the issue
