This is the INSTALL file for the alpha release of Felt.

First, read the README file.  You need a C compiler and X11R5 (including the
Athena widget set) to compile Felt.

Second, cd to the root of the hierarchy (./FElt) and do a "make config".
This will ask you various questions about your system and create a new
"Makefile.conf" file.  Each time you do a "make config", the configuration
script will use your old responses.  If you don't have a Fortran compiler
then enter a "none" in response to that question.  The geompack
library used for element generation is written in Fortran but C versions
as converted by f2c are provided.  Using a native Fortran compiler is
recommended since it will probably outperform the corresponding C code.
You don't need to have the f2c libraries to use the converted code.
The remainder of the questions should be relatively straight-forward.  
Afterwards, you can edit the "Makefile.conf" file by hand if you need to.
The entire package has been compiled and tested under SunOS (using gcc),
HP-UX 8.0 (using HP's cc), Linux, and SystemV386 (R3.2.2, using gcc).

Note that if you're using gcc, make sure that you use gcc's include files
and not the system's include files.  This shouldn't be a problem unless
you put something like "-I/usr/include" in your compiler flags.  Gcc has
its own ideas as to how some things like variable argument lists work.  For
example, if you get the wrong "varargs.h" file included then the diagnostic
and error messages will either report obviously incorrect values or will
cause a core dump.

Next, do a "make clean" followed by a "make all".  To install the package
do a "make install".  This will copy the binaries and manual pages to the
specified directories.

We personally prefer the 3d Athena widget set, if it's available on your
system and you want to use it, the only thing we recommend that you change
are the app-defaults ... simply uncomment the 3d stuff in the file
Velvet.ad in the bin/Velvet directory (and comment the 2d stuff).
