Hi,
How can I use a path relative to workspace_dir as a build flag?
I am trying to add include folders. Eg: I would like to do the following:
build_flags =
-I ${workspace_dir}/utils/segger_rtt/RTT
Please let me know, the docs are not very clear on this and I tried different things without success
Thanks
Just use -I utils/segger_rtt/RTT, PlatformIO will automatically resolve path from a current working directory (which is project directory).
This does not work when using the Native platform.
build_flags =
-Ilib/custom_arduino_fakes/
When checking the verbose output of the compilation, I see that it is always translated into the following:
-IC:\Users\ME\.platformio\platforms\native\builder\lib\custom_arduino_fakes\
Which is of course not the path of my project.
Only passing the absolute full path gets translated to the correct relative path, so this:
build_flags =
-IC:/Users/ME/Development/PROJ/Firmware/lib/custom_arduino_fakes/
gets translated into this:
-Ilib/custom_arduino_fakes/
Trying to access the default variables did not work because they were always empty here in this context for some reason I do not know.
Do you have any suggestion to be able to use a relative path inside my project here without needing to pass the whole absolute path?
Well, I found out how to get it working, for me I needed quotation marks to get it working. So just like this:
build_flags =
; -I "${platformio.workspace_dir}/../" ; This accesses the current project directory
-I "${platformio.lib_dir}/arduino_fakes/src/core"
Without these quotations it did not work.
