Hi David,

> My object files are always stored in a sub-directory within each

> environment and all the files do not have group write permissions

> I was wondering if there is a way in the MPC file to specify the

Thanks very much for your email.  Please send all questions related to
ACE mailing list or newsgroup, rather than to me directly since I travel
frequently and often don't have ready access to email.  See


for more info on how to access these resources.

In addition, to ensure that we have proper version/platform/compiler
information, please make sure you fill out the appropriate problem
report form (PRF), which is in


or in


in older versions of ACE.  Make sure to include this information when
asking any questions since otherwise we have to "guess" what
version/platform/compiler/options you've using, which is very
error-prone and slows down our responsiveness.  If you don't use the
PRF, therefore, it is less likely that someone from the core developer
team will be able to answer your question.  Naturally, we encourage and
appreciate other members of the ACE user community who can respond to
questions that they have the answers to.

If you need more "predictable" help please see


for a list of companies that will provide you with ACE
commercial support.

Thanks very much,
