I found some setting in mbed-os/tools/settings.py:
# Print compiler warnings and errors as link format
PRINT_COMPILER_OUTPUT_AS_LINK = True
but when I activate this in mbed_settings.py in my project root, it has no effect.
How to enable mbed_settings.py?
ok, mbed_settings.py is usually used by default.
But I’m using a configuration with multiple projects and one mbed-os, as documented in
https://os.mbed.com/docs/mbed-os/v5.14/tools/working-with-mbed-cli.html
But it looks like mbed_settings is ignored or not found in this configuration. When mbed-os is in the current project dir and the config var MBED_OS_DIR is not set, than it works and I can override PRINT_COMPILER_OUTPUT_AS_LINK.
When MBED_OS_DIR is used, the mbed_settings.py in the project dir is also not compiled by python.
another Edit:
Terrific! It works! I just had another mbed_settings.py in the mbed-os directory. This was not tracked by git, so I have overseen it. After deleting, the mbed_settings.py in the project root was used and PRINT_COMPILER_OUTPUT_AS_LINK is set as intended.
Now mbed-cli and VSCode work together perfectly, also with multiple projects in workspaces. I can really recommend this configuration.
