Re: Calling C from Ada - link problem

[Rush Kester <Rush.Kester@jhuapl.edu>]

You should try saving ObjectAda's LINK.EXE, CVPACK.EXE & CVTRES.EXE and
replacing them with the same programs from Visual C then relinking.

P.S.  Subscribing to and posting this on intel-objectada@aonix.com would
better target people who could answer ObjectAda specific questions and you
will find it very useful.
I believe you can also check the email archives using a web browse, see
