Steve,

 ...

The wnvblk_ entry point is contained in the wnvblk.for routine which
gets compiled into wnvblk.o and added to libmcidas.a.  The fact
that the linker can't find this entry point in your libmcidas.a
seems to say that the object module was not added to the library
in the first place.  This fits with libsdi.a not being created
correctly, and seems to point a finger at a problem with make.

re: I would love to find the real reason for the link failures

Thanks. I may take you up on this in the future, but right now I am
swamped with some other things.

OK.  I don't see this problem on Fedora Core 1, and I was running the
2.4.22-xxxx kernels there.

I will attempt to spend some time with this issue next week, but I
will be on travel, so it may have to be put off until mid March.

Tom,

Good news.  I got it to build after doing a upgrade of make. I upgraded
from

make-3.80-96

to 

make-3.80-101

Funny, when i ran yast to do a upgrade it did a lot of updates, I guess
they were only security updates.


I still had the initial problem of libsdi.a but I did what you
suggested in th first e-mail (that you also had to do on slackware) So
it seems there's still something wrong with that make.


Now to test mcidas and build ldm.

Thanks for your help.
