#160 install on x86_64 RHEL4 fails
I am attempting to install CDAT 4.0.5 on a x86_64 RHEL4
system. The problems that I am encountering can be
divided into compile issues and run-time issues.
I have resolved the compile issues. This has required
adding -fPIC to the CFLAGS and CXXFLAGS env vars, and
making adjustments to several configuration files so
that the /usr/lib64 and /usr/X11R6/lib64 are accessed
when loading.
However, I have encountered a couple runtime errors,
and I'm hoping that someone who know this code can help
me get it 64-bit clean.
Here is the results of running the test_script ...

Tests completed.
I have traced the first error to pp_read_all_headers()
in file
cdunifpp_read.c, where the code attempts to allocate
the "-1848901632 bytes" of memory (about line 560).
Perhaps the preceding seeks while reading the header
are mis-seeking resulting in out-of-frame reads.
Suggestions?
Thanks ... bob
