Did you check the log.do_compile to see what is actually being executed? That will tell you easily where you’re going wrong. Remember all bitbake is doing here is running ‘make’. If you want to pass specific flags, then pass specific flags (either by adding them to EXTRA_OEMAKE, which will get passed to make calls automatically, or by writing your own do_compile() that calls make). FWIW, my golden rule is that Makefiles Are Terrible and recipes that build them are always annoying, because Make has terrible semantics and writing a Makefile that behaves are you’d expect is surprisingly difficult.
