Compiling KHexEdit is very easy. The following should do it:
1 % ./configure 2 % make 3 % make install |
If you run into problems please report them to the the author Espen Sand or to the KDE mailing lists (Take a look at http://lists.kde.org/. Your question might already be answered).
Normally you must be root (have administrator privileges) to successfully do the "make install" step.
Note that you can specify a number of options to "configure". A common option is "--prefix". Using this option you can specify where your KDE base directory is. Common arguments to this option is "/opt/kde" or "/usr/local/kde". "configure --help" lists all available options.
