I took a look at the output you included in your attempt to build
the ldm-mcidas decoders:
>these are the setenv variables
>CPP_MCIDAS=-I/home/mcidas/inc
>LD_MCIDAS=-L/home/mcidas/lib -lmcidas

In particular, I note that the definition for LD_LDM will only be
correct if you have built the LDM from source and if you did not
follow the recommended procedure for building the LDM by release
number.
Typically, one downloads the LDM and unpacks it in ~ldm. This
will result in a directory whose name contains the LDM release
version. For instance, if you downloaded the source distribution
of LDM v5.2, the directory structure that you would end up with is
~ldm/ldm-5.2. When you install the LDM after the requisite configure
and 'make', 'make install' steps, you will end up with a directory
structure that looks like:
- bin
- include
~ldm - lib
- man
- src
The setting for LD_LDM for building the ldm-mcidas decoders would then
be:
LD_LDM='-L/home/ldm/ldm-5.2/lib -lldm'
not
LD_LDM=-L/home/ldm
If you do have a /home/ldm/lib directory, AND if libldm.a is in /home/ldm/lib,
then the problem is that LD_LDM does not identify libldm.a as a library
to search. The setting should look like:
LD_LDM='-L/home/ldm/lib -lldm'
Either of the above two conditions would account for the errors you are seeing
during the build. The definition of LD_LDM satisfys configure,
but it is probably the case that /home/ldm/lib either doesn't exist;
it doesn't contain libldm.a; and/or your LD_LDM doesn't name libldm.a
as a library to search.
The same sort of comments apply to CPP_LDM.
Finally, you note that you tried a couple of different things for LD_X11
including:
>also tried
>LD_X11=-L/usr/lib/X11 -lX11
The errors you reported in linking were the failure to find 'udebug'
and 'unotice'. Since these are entry points in libldm.a, changing
the reference to libX11.a won't affect anything.
