It furthermore checks the current C++ language standard set in IDF is the expected one. ## This App Broke My Build :( It is likely that one of the following situations occurred: 1. The language standard for IDF has been changed without changing the test in this application. 2. Code incompatible to C++ has been added to one of the public header files in IDF. Check the C++ documentation section [Combining C and C++ code](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/cplusplus.html#combining-c-and-c-code) for more details. ## Adding New Test Create a new file `main/test_.cpp` and add it to main/CMakeLists.txt. If you need to check specific compiler flags, use `set_source_files_properties` CMake function to adjust the compilation flags for the given source file.
