Fw: problems building RTEMS 4.6.99.3

[avy st]

Hello All,
  Someprogress:  after doing some searching, the offending directory (where the wrong check is made) is rtems/testsuites/samples.  deleting the samples directory from the testsuites directory allowed the build to continue (and to fall on the next bug, but this will be reported shortly in another thread).
  I'm far from being an expert on the configure.ac and makefile.am stuff, but from looking into configure.ac in the testsuite/samples directory I suspect that the problem shows up because I'm building with --disable-cxx (I also built the compiler without c++ support, since I'm looking for Ada and C only).
  Can any expert comment on that?
Thanks everybody

Sorry that didn't work.  Try linking to the host flavor?

Anyway, I agree it's only a hack, but it's the best I can do for you
until one of the more knowledgeable people give you a better one!

Good luck!
