This comment in original issue: The gpgme-config scripts goes along with the gpgme.m4 code. A .pc file won't be able to do what we can do with this combination. Makes me think that if we implement .pc.in which generates correct .pc from gpgme.m4 he won't be against accepting such patch upstream. I think that biggest reason against -config scripts was that they aren't cross-compile friendly (not sysroot-aware) so you either have whole path to sysroot hardcoded in -config file and then have to mangle it for target -dev package or vice versa and you need to prefix returned values (like -I -L flags with sysroot). > 2) Make an exception to the policy on -config scripts for gpgme. > > I haven't really followed the discussion on why -config scripts needed to be > removed so I'll put this question to other OE developers.
