What am I doing wrong?


You cannot tell from the test summary. You should look at the various testsuite *.log files and analyze the failures on a case by case basis. Usually forthe number of failures you are seeing, there is a common problem that is causing them all.


You can look at: http://gcc.gnu.org/ml/gcc-testresults/ to see how your results compare against those of others.

I built GCC 4.4.0 on a Sparc Solaris 10.

The build went thru fine, but most of the tests
failed,
last fragment from make check is below.
When you run "make check", don't use the -j option. It is doing
something which is not supported by your host
tools.
make -jN check is
only well-tested on GNU/Linux.  If you have the
time,
it would be
helpful if you could look into the problems on your
system
and fix them.
