Since this mail was posted, there has been a significant work on the
-forge tree, you may want to have a look at the README
git://git.xenomai.org/xenomai-forge.git
This is NOT production grade yet, current lack of documentation is
blatant as well, but AFAICT, this meets my expectations design-wise, and
runtime-wise. Lot of work ahead though.
You may want to try running the psos testsuite from lib/psos/testsuite,
over the so-called "Mercury" core. You could do this as follows:
$ .../xenomai-forge/configure --with-core=mercury --prefix=/
$ make install DESTDIR=/foo
$ cd .../xenomai-forge/lib/psos/testsuite
$ make DESTDIR=/foo test (*)
(*) will require the current account to be sudoer
