[Wien] error while loading shared libraries

[Laurence Marks]

In some of the more recent unix releases the at/batch format was
changed to not propogate some environmental variables such as
LD_LIBRARY_PATH -- be aware that the man page may not have been
updated. To work around this there are many possibilities, depending
upon what rights you have:

1) Edit the top level Wien2k run_lapw scripts and add lines to set
LD_LIBRARY_PATH or similar. I would suggest doing something like
adding to all the run scripts

if (-e $bin/local_options) then
        source $bin/local_options
endif

Then put what you want into local_options. This will give you a lot of
flexibility. It could even be changed simply to allow individual users
to have different options, e.g. via a file $HOME/.wien_options .

2) Add lines to $WIENROOT/parallel_options -- this is read by
lapw0para, lapw1para and lapw2para so will probably handle most cases.

3) If you have su rights, edit /etc/ld.so.conf so it contains the
appropriate libraries. Even if you do not doing a ssh onto a node and
then "ldd lapw1" will give you an idea about the issues -- see the man
pages for ldd and ldconfig.
