Hmm...  I sent you the previous note after doing a build on my
dual 3.2 Ghz FC4 64-bit work machine on which I had run into the same
problem you were reporting.  I figured that if adding the '-j 1' flag
to make worked on my machine it should also work on yours, but it
evidently did not/not entirely.

The wnvblk_ entry point is contained in the wnvblk.o object module.
Try adding that module to the McIDAS library and continuing make:

<as 'mcidas'>
cd ~mcidas/mcidas2005/src

ar r libmcidas.a wnvblk.o
ranlib libmcidas.a

make -j 1

 -- or --

make -j 1 all

Follow this same procedure for each additional missing entry point
you run into.

Again, please let me know if this works for you.

Cheers,

Tom

Hi Tom,

It is pretty awkward that even with -j 1, it still breaks the
compilation sequence...
But your suggestion did work!!

Many thanks,

Christian
