The computing center I use is in the process of moving from a Linux
cluster to an IBM-aix based one. Unfortunately, the structure binary
will not run on this cluster. I am trying to recompile the source code
to produce a binary to work on the machine to no avail. The assembler
runs though a bunch of lines with an error message that says:
"Only .llong should be used for relocatable expressions." The problems
appears to be that I am trying to compile on an IBM-aix machine. The
available gcc compiler is gcc/4.2.0-ibm--binary xl/10.1 . Does anyone
have any tips to help me along here? Thanks.

fixed the problem. You have to include the option '-maix 64' when
compiling because gcc automatically assumes 32 bit (or something like
that). but the gcc on the cluster apparently does not recognize
'-static- as a gcc option. If I use '-s' the executable compiles ok,
but then it seems to hang at

Reading file "mainparams".
datafile is
testdata1

I am guessing that '-s' is not an option for static linking. Does
anyone have any advice on how to solve this issue?

With some help from the computing center, I managed to solve the
problem of using STRUCTURE on a system running an aix os. In params.c
and datain.c, change "char next" to "int next" under ReadFile() (line
208 I think) and ReadData() (line 76), respectively.

The problem, as I had been told, is that
"Since if next is char it cannot take a numeric value=EOF. Hence the
compiler warning.
....
Presumably, the Linux C compilers dont care about this distinction,
which is why it works on BCX, but the IBM xlc compilers are more
stringent."

It would not work under the gcc compiler either.
