Hello,
when transitioning a project to non-recursive Automake, using %reldir%,
you lose the ability to define per-directory AM_{CPP,C,CXX,LD}FLAGS.
With recursive Automake, you can simply set AM_CFLAGS in each
Makefile.am. Attempting the same in a non-recursive setup would modify
the single, global AM_CFLAGS, which may not be desirable.
The only solution seems to be to heavily expand the fragments:
AM_CFLAGS = -g
bin_PROGRAMS = foo bar baz
becomes
bin_PROGRAMS += %D%/foo %D%/bar %D%/baz
%C_foo_CFLAGS = -g
%C_bar_CFLAGS = -g
%C_baz_CFLAGS = -g
(repeat for AM_CPPFLAGS, AM_CXXFLAGS, AM_LDFLAGS).
This gets unwieldy in cases of many programs and libraries. As a side
effect, Automake will emit explicit rules, making the Makefile even
larger, though that's not much of a problem I think and is probably not
avoidable.
Is there any other solution available? I have tried to define
directory-level AM_CFLAGS, like
AM_%C%_CFLAGS = -g
(applying to all targets that start with %C% after expanding) but they
are not used.
If there are no other solutions, would the above idea considered if
someone posted a patch?
Best regards.
