Hi Christian,

I have been seeing this failure more and more under Linux as machines
and the OS get faster.  What is happening is that the object modules
that are destined for the McIDAS (libmcidas.a) or SDI (libsdi.a)
libraries are not being correctly added to the library, so linking will
fail with errors like what you are reporting ('undefined reference').
This is apparently being caused by 'make' trying to be faster by
running simultaneous processes.  Interestingly, I _never_ see these
errors on my home development machine, a _slow_ 700 Mhz PIII running
FC4 32-bit.

You can force 'make' to run in "single job mode" (to serialize the build
process) as follows:

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

make -j 1                   <- build McIDAS-X

 -- or --

make -j 1 all               <- build McIDAS-X and McIDAS-XCD

Please let me know if this works for you (it just worked for me on a
dual 3.2 Ghz EM64T machine running FC4 64-bit).

Cheers,

Tom
