I have just moved to a new machine and I found that the MPIR tests
would not always build correctly with Visual Studio running on a multi-
core development machine.
I had all these tests in a single directory and this meant that when
Visual Studio was running multiple build threads, sometimes both would
try to write to the same log file and find that the other thread had
claimed it. When this happened the build for the thread that cannot
write the log file reports a failure.
On my old machine I didn't notice many failures but with my new i7
(with 8 hardware supported threads!) I am seeing many thread conflicts
during the build of the tests suite so I have had to modify the build
to use a different configuration in which each test has its own
individual build sub-directory.
I have tested this faairly extensively and I believe it is all OK but
it is a big configuration change so I would be grateful if anyone who
is able to build MPIR and the MPIR tests on a Windows system could
check out and test the revised Windows build configuration in SVN (the
MPIR build itself is unchanged - only the tests are affected).
best regards,
Brian Gladman
