[Ace-users] [ace-users] using the build scheme

[Finer, Howard]

Due to MPC related changes in 5.6, libACE is no longer automatically
linked in.  The makefile must have an explicit -lACE to be linked
against it.

I had a similar issue that I had worked on with Riverace, and this was
Steve's response:
This change was made to ACE to better support MPC-generated makefiles.
Unfortunately, it was not called out as a user-visible change by the
author. I apologize for this confusion.
Unlike the __prebuild__ issue, there's no way to easily re-add this
without causing issues with all current makefiles. The only way to
resolve this is to explicitly add -lACE to your LDLIBS variables where
needed, or regenerate your makefiles with MPC.

Hi Sayanthan,

Johnny's advice to look at MPC is good. However, you can also use the
Makefile included with the book's examples. In this case, look in
ACE_wrappers/examples/APG/Logging. The example you've included below
looks a lot like Simple1.cpp

Best regards,
-Steve
