I have a c++ file and two header files. I want to include a different .h file into the c++ depending on the environment. I have tried stuff with src_filter but it does not seem to work.
Looks like you need build_flags. For example,
[env:myenv1] platform = atmelavr framework = arduino board = uno build_flags = -DHEADER_1 [env:myenv2] platform = atmelavr framework = arduino board = uno build_flags = -DHEADER_2
#ifdef HEADER_1 #include "myheader1.h" #else #include "myheader2.h #endif
