It would work and would be BSP independent. But it moves the path knowledge
to the command line.
Could it be done with just "/home/hf/development/rtems/b-leon2" and the
user configuration file use @TARGET@/c/@BSP@/cpukit?
Yes of course.
Then I could use the option --rtems-builddir as prefix for the directory
containing the test cases. Currently the path to the test suite is also
required to be an absolute path in the execution command for rtems-test e.g.
$HOME/development/rtems/b-leon2/testsuites/
Then the option could be --rtems-builddir or something similar.
OK.
Just make sure it works and is easy to explain. :)
I am also thinking that as we move to waf, this might be easier to adapt
without
changes.
What do you mean by that?
We have plans to switch the build system from autoconf/automake to waf. This
would
change the path to the object files in the build tree. Not sure what other
impact
it will have. May require listing individual files. Not sure.

It is possible but it wouldn't be something done on a regular basis.
