Building the X-GEN package is generally easy. The most secure way to build
it is to compile it from source on your target computer, as follows.
In each of the commands shown below, the "%" is intended to show a system
prompt. Commands that you type are in typewriter font:
That's the whole story. The executables will be installed in /usr/bin.
- Download the source tarball,
- Move the tarball to an appropriate top-level directory.
Thus if you plan to keep the software in /opt/xgen but it was
originally downloaded into /home/johnsmith, then:
% cd /home/johnsmith
% mv xgen-5.8.0.tgz /opt/xgen
- Unpack the tarball:
% tar xzvf xgen-5.8.0.tgz
n.b.: On some systems you may have to use gtar instead
of tar; on others you may have to do the uncompression separately
from the unpacking, e.g.
% mv xgen-5.8.0.tgz xgen-5.8.0.tar.gz
% gunzip xgen-5.8.0.tar.gz
% tar xvf xgen-5.8.0.tar
- Configure the package for your local system:
% sh ./configure
- Compile and link it:
n.b.: On some systems, including many Irix and Solaris systems,
you will need to use gmake, gnumake, or even
/usr/sfw/bin/gmake instead of make.
- Install it. There are three cases of how you can do this.
- If you are a superuser, you can do this simply:
n.b.: If you had to complile with gmake or gnumake
you'll have to do this step the same way.
- If you are not the superuser,
but you are set up to obtain superuser privileges using sudo:
sudo make install
- If you are not the superuser,
and you are not set up to obtain superuser privileges using
sudo, then do the following:
Password:(your system's root password)
If you have a 32-bit system, the libraries will be in /usr/lib.
If you have a 64-bit system, the libraries will be in /usr/lib64.
The system resources (specificially, the pixel-to-centimeter conversion
files for specific detector types) will be in /usr/share/xgen, and
the documentation will be in /usr/share/doc/xgen.
If you prefer to use the pre-compiled binaries, you can download
the appropriate gzipped tarball for your system and insert the binaries
in /usr/bin or some other directory in your users' path.
If you want to use the shared-library versions, put the
shared libraries in /usr/lib. Currently, X-GEN is not set up for
downloading the 64-bit Linux libraries from the
website; you'll have to
compile and link those as described above. If you'd prefer to use static
libraries, then you don't need to do anything special with the library
X-GEN in its full version requires Motif, curses (or ncurses), libz,
and a working version of the library call for setenv.
If your system lacks one or more of those packages,
you should build X-GEN from source; the configure
script handles the absence of any of these packages.
Irix is a special case: the X-GEN package as built for Irix provides
a setenv functionality.
Of course, if you build X-GEN without Motif, curses, or libz,
the functionalities associated with missing packages will
be missing in the X-GEN package that you build.
I would be happy to attempt a port of X-GEN to other operating systems.
