Now as our host is ready, we can start working on the actual swars sources. Go to that folder, and generate build scripts from templates using autotools:

autoreconf -ivf

Next, proceed with the build steps; we will do that in a separate folder.

mkdir -p release; cd release

autoreconf -if

To build:

1) If you have made any changes in the tool directory,
rebuild it first. If you have not, you do not need
to do anything there.

2) If you are on a Linux system, try a make with the
existing Makefile. It works for me.

Otherwise your next best thing is to hack the Makefile.

Or, you can try Imake by entering "xmkmf". But it's been
awhile since I checked out the Imakefile.

The provided Makefiles :

        Makefile.solaris:               Sun Solaris 2.4+
        Makefile.linux:                 Linux
        Makefile.ref:                           Generic (actually Linux...)

3) Then you can:

        1)      make clean
        2)      make depend
        3)      make
