Apart from the obvious (that you are using Window Maker ;-))
the only requirement for building wmpager is the XPM library. The XPM library is available for about every platform running
Window Maker and if you have a Linux box with a standard installation
you'll probably already have the XPM library installed as
/usr/X11R6/lib/libXpm.a (with the include file located at
/usr/X11R6/include/X11/xpm.h). wmpager has been successfully built on various Linux versions,
Sun Solaris 2.6 - 2.8 and even Max OS X (Darwin) (with a little
tweaking). The current stable release of the wmpager is release 1.2
(build 1.4). That's the first version which is being made available via
SourceForge: wmpager-1.2.tar.gz (source tarball) The source tarball contains all sources and documentation
to build the wmpager. There are no binary builds of the wmpager (and I do not
ident to release binary builds). For over a year release 1.1 (build 1.13) has been
the current stable release to use. With the project
move to SourceForge a new release has become available
and version 1.1.1.13 has now become obsolete. For archival purpose (or if you have a problem with
release 1.2) you may download the source-tarball of
release 1.1 that was made prior to the move to
SourceForge: wmpager-1.1.tar.gz (source tarball) |
