Subject: Specifying CFLAGS for a directory on the command line
Date: Fri, 9 Jun 2023 18:23:14 -0400	[thread overview]
Message-ID: <ZIOmUkXlegycIExQ@moria.home.lan> (raw)

Hello kbuild maintainers & list,

Years ago I used to be able to specify additional CFLAGS for a specific
subdirectory on the command line, which I used for enabling gcov
profiling without editing the subdirectory makefile, like so:

  make GCOV_PROFILE_fs_bcachefs=y

But this stopped working ages ago, I believe in the 3.x era. Does anyone
know if there's a more modern way to do this?

Cheers,
Kent
