XFCE requires the XForms library version 0.81
or above. You need to install this library BEFORE compiling or using XFCE.
1) Where to get the XForms library
Visit http://bragg.phys.uwm.edu/xforms
2) Download the version of the library for your platform.
For example, if you download the version for Linux, you'll get a file
that looks like that (depending on which version you download, of course
!)
This file is a tar archive compressed with GNU Zip, just like XFCE distribution.
3) Decompress this archive in a base directory of your choice
(/usr/src, for example)
$ tar -xvzf bxform-linuxELF.tgz -C /usr/src
That should create a subdirectory /usr/src/xforms
4) Install the library and the C headers
Copy the libraries to /usr/X11/lib :
$ cp -ivd /usr/src/xforms/FORMS/libforms* /usr/X11/lib
Copy the C headers to /usr/X11/include/X11 :
$ cp -ivd /usr/src/xforms/FORMS/forms.h /usr/X11/include/X11
Please note that the /usr/X11 directory could be system dependent. On some
system, it could be /usr/X11R6 or /usr/X386. Of course,
in this case, replace X11 by whatever suits your system.
5) Reconfigure ld (Linux dynamic library loader)
As root, type :
you should see libforms in the list of known libraries.
