[Ace-users] Re: [ace-bugs] [tao-bugzilla] [tao-users]: ["tao_idl -GA" can generate incompilable code]

[Douglas C. Schmidt]

Hi Silas,

   Thanks for using the PRF.

>     ACE VERSION: 5.4.8

Please upgrade to ACE+TAO+CIAO x.5.8 (i.e., ACE 5.5.8, TAO 1.5.8, and
CIAO 0.5.8), which you can download from

http://download.dre.vanderbilt.edu

under the heading: "Latest Beta Kit".

The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in

http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/docs/ACE-bug-process.html

Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out

http://www.dre.vanderbilt.edu/support.html

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

Thanks,

        Doug
