I wanted to chime in and say that that would be a very useful feature. Too often I find myself in a need to add extra py script overcome pio's automatic passing of flags to gcc/g++/ld. E.g. this: https://github.com/platformio/platformio-core/issues/594
I'd like to upvote this - it's really cumbersome that I need to prepare an external extra_script= whenever I want to specify some linker flags. Embedded development frequently requires custom linker flags (linker script, etc), so it should be easy as build_flags= to specify one.
The most recent one I was caught is that passing build_flags="-g" does not actually include full debug_info in generated ELF file (AVR target fails to include reference to source/symbol info in included debuginfo). I had to use extra_script= to pass "-g" and get avr-objdump -CDS
working. "-g" options is just so common that I feel this should be much easier.
I'd like to upvote this too
It seems like this is the intended solution for these issues so I'll make a comment here. https://github.com/platformio/platformio-core/issues/594 https://github.com/platformio/platformio-core/issues/843
Is it not a bug that pio only passes -Wl
build_flags
to the linker when there are more flags that are for linking?
Allow passing build flags to the specific scope. See https://docs.platformio.org/en/latest/projectconf/section_env_build.html#build-flags
