#86: Simplify the creation and maintenance of Makefile.am's under milena/tests/ --------------------------+------------------------------------------------- Reporter: levill_r | Owner: levill_r Type: enhancement | Status: new Priority: minor | Milestone: Olena 1.1 Component: Milena | Version: 1.0 Resolution: | Keywords: --------------------------+------------------------------------------------- Changes (by levill_r): * milestone: Olena 1.0 => Olena 1.1 Old description:

Currently, a `Makefile.am` in a subdirectory of `milena/tests/`, e.g. `milena/tests/foo/Makefile.am` looks like this:

{{{ ## Process this file through Automake to create Makefile.in -*- Makefile -*-

include $(top_srcdir)/milena/tests/tests.mk

check_PROGRAMS = \ bar \ baz

bar_SOURCES = bar.cc baz_SOURCES = baz.cc

TESTS = $(check_PROGRAMS) }}}

But as the `check_PROGRAMS` variable grows, so does the number of `*_SOURCES` variables.

Automake provides a solution to handle this more or less nicely when tests are written in the C language: when a program `quux` listed in `check_PROGRAMS` has no corresponding `quux_SOURCES`, Automake acts as if the following line were written in the `Makefile.am`:

quux_SOURCES = quux.c

It would be nice from Automake to provide an option to change the extension of this pattern from `.c` to `.cc`. Unfortunalety, we cannot. :-(

A solution would be to ''generate'' the list of sources with a shell script, as we do it in the `Makefile.am`'s of the tests of the Tiger Compiler project. I we do so, careful with the dependencies!
