5 years ago Hi @thepian, unlike the Make based build system which globs source files by default, in CMake the source files need to be listed in CMakeLists.txt: https://github.com/espressif/esp-idf/blob/abea9e4c02bb17e86298aec4e299780399e4789f/examples/get-started/hello_world/main/CMakeLists.txt#L1.
Globbing is also possible, but not recommended. Please see https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system-cmake.html#file-globbing-incremental-builds for details.

Problem Description
I'm trying to create a C++ based project. I've copied hello world and renamed the main to .cpp (also tried .c++) The regular make goes through fine, but
idf.py buildfails. I tried deletingbuild/main, no dice.Expected Behavior
Build pass for simple case
Actual Behavior
Fail with output below.
