Linux users need Motif to compile and run the program (if the program
complains about
"viewmol: can't load library 'libXm.so.1'
" Motif is missing). Motif is
available from http://www.motifzone.org/download/. The Motif clone Lesstif
(http://www.lesstif.org/)
can be used with Viewmol starting with version 0.81. There are, however, some
glitches with Lesstif (e. g. shortcuts don't work).
If you want to recompile the program and you are running one of the supported
operating systems (this may be necessary on IBM workstations since the formats
of the executables are not compatible between different releases of AIX -
don't worry, IBM didn't) you may type make
(this tries to build
VIEWMOL using OpenGL on all operating systems except on Linux and FreeBSD,
to build using Mesa type make viewmol_mesa; make tm bio readgauss readmopac
readgamess
).
The shell script getmachine
determines the operating system you are
running and sets some options for the compiler. If this does not work you
should have a look into the Makefile
. The options set are explained
there. They are the following:
OPT
-O6 -mX
where
X
may be 486
, pentium
, or pentiumpro
;
-O2
otherwise).
CFLAGS
LDFLAGS
INCLUDE
LIBRARY
LIBS
getmachine
shell script will ask you for the path names to the TIFF
and Python libraries and to the include files necessary with these libraries.
If you compile with Mesa the script will also ask you for the location of the
Mesa libraries and include files. You may specify these path names using
environment variables if you put the name of the variable in parentheses
(e. g. $(HOME)
). These path names are assigned to the LIBTIFF
,
TIFFINCLUDE
, MESALIB
, MESAINCLUDE
, PYTHONINCLUDE
,
and LIBPYTHON
flags and stored in a file .config.<OS>
where
<OS>
is the output of the uname -s
command on your machine.
If this file already exists, getmachine
does not ask for these path
names.
Silicon Graphics compilers on 64-bit operating systems (IRIX64 - R8000, R10000, R12000) will produce a lot of warning messages concerning casts of pointers to integers. These can be safely ignored.
The make procedure will build the program in a directory whose name depends on the operating system and type of CPU you are using. You will find all executables in this directory. After compilation follow the steps under Installation to complete the installation.
