Re: X11 library error

Hi Jenny, Rick,

I ended up switching to the Ubuntu (Debian based) Linux distribution. I found that attempts to install packages (like X11R6 static libraries or the g77 fortran compiler) on Mandriva usually resulted in "dependency hell." I recently learned that "dependency hell" is the Linux lingo for searching for a package's dependent libraries, only to find that those libraries have many dependent libraries, and so forth. Once I learned about Debian's "apt-get" feature, I was sold immediately. After some practice with "apt-get" and Debian's online list of packages (instead of the rpm's for RedHat-based distributions), I managed to install all of the required X11R6 static libraries. This solved my persistent X11 library error when compiling and linking.

One word of caution to Ubuntu users: for some reason, Ubuntu puts the X11R6 libraries in /usr/lib instead of /usr/X11R6 where they normally are.

Thank you for your help.

I think this was my post that you're referring to. At first I
installed the static versions from xfree86 but it broke Xwindows on
other parts of my machine. So if you're running Red Hat, the easiest
way to fix this is to install the developers x11 rpm. The current
one is:

xorg-x11-devel-6.8.2-1.EL.13.25.1

That fixed both my ncarg problems and my other X problems.
Apparently only the developers rpm includes the static libraries.
