Fw: problems building RTEMS 4.6.99.3

Hello Bob,
I saw the line. It looked wierd to me as well, but I had no clue why the sanity check refered to /lib/cpp. You gave a possible answer - there are some configurations where there should be a /lib/cpp, and probably what we see is a configuration file bug, that mis-interprets my configuration. The question is - where, and how do I locate the bug?
As for your suggestion, I tried it (I tried linking it to the target flavor, though). It didn't work. Even if it did, it would be a hack, and a correction was still needed.

Hi Avy,
Not sure, but don't these lines look funny to you?
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
I'm not sure which cpp it is looking at (host or target), but I would
expect something like /usr/bin/cpp (host) or
/opt/rtems-tools-4.7/bin/powerpc-rtems-cpp (target). I know _my_ cygwin
has no /lib/cpp. I did check, and my Gentoo Linux box _does_ have a
/lib/cpp. Again, I don't know what the configure script is looking for,
but in case it is looking for the host flavor, I would try (naively,
perhaps) creating a symbolic link (e.g. ln -s /usr/bin/cpp /lib/cpp) and
see if that works.
Funny, I didn't have that problem...
