> thanks for that John, I'll give it a go. Looks like you are using later versions of gcc and binutils than I was trying. I was using the versions identified by the 'download helper' so I'll try these new ones at some point next week if I can get the time. I'll let you know how it goes...

John started with tools normally used with the 4.7 development
tree.  He asked earlier how to know and I didn't have a
good answer.  The best I can offer is that

http://www.rtems.com/ftp/pub/rtems/linux/redhat/7.3/i386/rpms/rtems-4.6/

has the tools that are matched to 4.6 and are used to test with.

Replace 4.6 with 4.7 in the above URL and you end up with the tools for 
the development tree (CVS head).  The RPMs are built to install into
/opt/rtems-4.6 and /opt/rtems-4.7 and the intent is that you would
switch toolsets as you switch between RTEMS versions.

In general, it should be possible to use a newer toolset if you
stick with the 4.6 newlib versions and patches.  But we don't
test that way.  Once a release branch is cut, the toolsets doesn't
get major updates.  It is just too dangerous.

In this particular case, gcc 3.2.x is that last series that
cross-Ada seemed to work well.  gcc 3.3.x looks good for
C and C++ on the development trunk.  I am flushing out warnings
with it.  I have used gcc 3.4.3 with patches and it also
seems OK.  We really need to focus on resolving issues in the
upcoming 4.x gcc series.
