Bert, Wonderful, thanks--it works!
Randy Kramer PS: Ignore all of the following, it's just me trying to summarize where I am (and adding some notes about ldconfig and /etc/ld.so.conf and a problem the first time I ran first as myself). The command line that worked: cc -o first /rhk/X/motif_tut1.c -lXm -lXt -lX11 -I /usr/X11R6/include/ -L/usr/X11R6/lib (And now I can adjust that to compile and run anywhere (adding paths to the file name, or moving back to /rhk/X) and not as root.) (Aside: At first I thought I had a problem in that when I ran ./first as myself, the window with "hello" didn't pop up. Then I switched to root and it worked fine. Then I switched back to myself and it worked. Who knows--for now it seems to be working--if I run into a problem in the future, I'll figure it out or ask a question.) In my earlier post, I forgot to mention that I had added some lines to /etc/ld.so.conf and then run ldconfig, but that didn't seem to help. The current content of /etc/ld.so.conf is: include ld.so.conf.d/*.conf /usr/X11R6/lib /usr/lib/qt3/lib /usr/X11R6/include/Xm /usr/X11R6/include/X11 /usr/X11R6/include I added the last three lines, but since, afaict, they had no effect, I will delete those and try the cc command again (just to confirm that my changes were unnecessary). Yup, deleted those lines and ran ldconfig again, the cc command still works. But, oops, small (??) problem--if I run ./first as myself, it seems to run, but the window with hello doesn't pop up. If I run ./first as root, the window pops up. A quick look at the permissions doesn't tell me anything useful, the file is executable by everyone (755 permissions) (and owned by me). For now, I won't worry about this--well, OK, maybe I'll move this back to the non-ignore part of the post and see if Bert or someone else can tell me the problem.
