Tried to use X-Windows in Fedora 14. After installing the following packages, openmotif-2.3.3-1.fc14/x86_64.rpm, openmotif-devel-2.3.3-1.fc14/x86_64.rpm,and libX11-devel-1.3.4-3.fc14.x86_64.rpm, all the files using X-Windows(or X11) got compiled without any error. However,it failed during the linking because of the error "cannot find -lXm". Checking \usr\lib and \user\lib64\X11, I did not see any libraries related to X11. It appeared that the X11 libraries were not installed at all. Need help to figure out what steps or package(s) are missing. Thanks.

Did you use the recommended way for those rpm's
" yum install ?????? "
or did you grab random rpms from random websites

if the later there are a few incompatible sources and you might have KILLED the install

How ???

unless you did NOT install the default GUI ( Gnome2 ) then it WAS installed by default at time of install

if you ONLY installed the TEXT ONLY - no gui then you would need to install a gui
like gnome
double check the spelling from the list of installable groups
x11 would be installed and there would be no need to try to install it if gnome,kde,lxcf,.... are installed

as to "Tried to use X-Windows"
boot the computer the gui pops up .There is a 3 sec. countdown then the normal boot
that there IS x window being used


that makes no sense
installing a rpm DOSE NOT build software
rpm's ARE prebuilt all ready compiled programs -- you do not "compile" them

This is what I did. I used Fedora-14-x86_64.DVD to install the Linux and I checked almost all the possible boxes (or options) during the installation. I also used "yum install ---" to install all the other openmotif-devel and libX11-devel three packages.

Entered "yum grouplist" and found the following installed group lists:
:
:
KDE Software Compilation
KDE Software Development
GNOME Desktop Environment
GNOME Software Development
Legacy Font
:
X Software Development
X Window System

As above shows the X Software Development package seemed to be installed. But when I tried to compile my X-Windows application (not the packages)and got this "cannot find -lXm" error.

I wonder what X libraries are missing or something else?
Thanks,

that right there might be the problem

installing EVERYTHING
gnome
kde
xfce

ALL web development
ALL desktop Development
all database development
EVERYTHING

has been known to install a NON working Operating system


What is it and where did you get it
HOW are you "compileing it " - the step by step would help
was it wrote for the VERY OLD xfree86 of MS windows ? ( think win 98 & xp )
If so you will have problems on any modern OS

I tried to re-install Fedora 14 again without including those Web, desktop,.. stuff. I also used "yum install" to install openmotif-devel, libX11-devel and xorg*. Well, the error message was the same - "cannot find -lXm". I started to wonder if X11 libraries were really supported in Fedora 14. No idea where I can get the answer.

What I am trying to do is to port an application written more than 10 years ago for running on Unix to Linux platform. I was told Fedora was a good one to pick and didn't expect this X11 issue. Not sure if I can try to use the xfree86 libraries in Fedora 14 or I should just explore other Linux OS for 64-bit. Thanks.

that is the problem


in a MS windows analogy
that x windows program is like a windows 95 program ( 16 bit)
and you are trying to build it on windows 7 64
WHO told you that ????
fedora is the like the Developers BETA preview of windows 8
it is THE NEWEST OF THE NEW

a old x program coded for a VERY old version of x on a NEW os
-- wont work ---

delete it and start from scratch
wright a 100% NEW version
scrap the old


now you might have ? maybe ? a 5% chance on CentOS 4.9
mabe
but you will need to install a VERY old version of gcc something like gcc2.8

-- i would not even try


do a 100% NEW rewright of the program
from the ground up

delete the old one

OK! I got the message. Your help is really appreciated. Best Regards.

Hi -
"libXm" is an old, mid-1990's GUI toolkit called "Motif". There's an open-source implementation, called "Open Motif", here:

http://www.ist.co.uk/downloads/motif_download.html

It couldn't hurt to download it, even though it sounds like you've downloaded some (or all) of Open Motif already.

It also couldn't hurt to see if you've already got some equivalent of "libXm" (perhaps called something slightly different) and rename it "libXm" or create a symbolic link ("ln -s") to alias it to "libXm".

Yet another complicating factor could be 32-bit vs. 64-bit libraries in the mix.

'Hope that helps .. PSM

We switched to use CentOS 5.7 and the missing X11 libraries issue went away. Our application was successfully compiled and ran.
