HELP!!! I can't build my old helicopter projects anymore (Linker step failure)

[Marc-X]

Dear Gods,

After fiddling with the MP for a while, I went back to see if I could
start the work of porting the MP-H project to the "new" libUDB and
libDCM format. When trying to build my old projects, I get a kick in
the face by my linker.

I have upgraded MPLAB since the last time I built the MP-H projects.
I have tried to re-create them from "scratch" by deleting the .mcp
files and even un-packed a "fresh" copy of MP-H_v2. Nothing will work.
It always halts on the link step:

Below is a cut from the output window:

Cheers!

Marc do you have libdsp-coff.a included in the project? Looks like you are
not linked to the matrix/vector libs.

John,

Thanks for your help.

I'm not really sure anymore. I just did a total clean out of the
directory, and then packed out a "fresh" copy that compiled.
Now I'm back in the saddle, trying to ride this bull again!

In other words: Something was wrong in my configuration or directory contents.

Cheers!

Marc
