Automake community:
I would be very thankful for any advice on the following:
I have an embedded platform for which I override all the make rules by
writing the make rules by hand in Makefile.am. I have tested this out,
and it works great, but because we have many unit tests, I have to copy
and paste the rules over and over and over as we add unit tests. This
is just getting unweildy if I ever have to adjust the rule a little bit. I
want to figure out how I can have automake create the correct rules for my
embedded platform for each item in bin_PROGRAMS.
It is not a problem for me to modify scripts which are part of the
Automake install, if that is the right solution. We currently use a
customized Cygwin environment to build, and changes to this Cygwin
environment will not affect the rest of my system in any way. I have
looked through the index of autoconf macros, and I don't see anything
directly applicable, and I don't think BUILT_SOURCES is what I am looking
for either.
My rules are copied at the end of the email.
Also, the 3rd party libraries which I am linking have circular
dependencies, and so I end up needing to use the --start-group and
--end-group flags in the linker command line. I haven't been successful
trying to figure out which libraries to list in what order, although I am
getting closer. Automake complains if I put --start-group in
networktest_LDFLAGS or in networktest_LDADD. Is it not possible to use
this flag in Makefile.am without defining custom rules?
And the very last thing, Automake 1.10 complains about the "$(shell pwd)"
in my 'debugfile' definition in Makefile.am, but Automake 1.9.6 handles it
just fine. Which one is confused or how should I write this?
