[This is really for Scott Weitzenkamp. Our mailer can't handle uunet address. Sorry for wasting bandwidth.] > How hard is it to make SunOS shared libraries for Motif 1.1.2? Building sharable library for motif is easy. Just compile the motif files with the -pic flag and link the object files (ld -o libXm.so.1.1 -assert pure-text *.o) . One complication is that in 1.1 motif has grown to size beyond what Sparc can handle, so you need to splt the library into two and probably call them libXm1.so.1.1 and libXm2.so.1.1, and your applications will have to link with -lXm1 -lXm2. You can play with your Imakefile to make it happen, but since it's more or less a one time deal it's easier to just tweak the make file. > Does OSF have any plans to support this in a future release of Motif? I don't work for OSF so I can't speak for them as far as plans to support this. I guess they have their worries, too, because they probably want to do it on all platforms, and that may be a task of reconizable size to them. (This is just an observation, not a flame) So, in a nutshell, the last word from OSF was that they have other priorities and this one is not one of them. > is there any kind of FAQ for motif-talk If you stick around on motif-talk long enough there will be a FAQ distributed every now and then, by Jan Newmarch (jan@echo.canberra.edu.au) in Australia. There's not mailing list for this FAQ, so please don't post a message asking to be put on the list. -kam

This can be increased to allow 32 bit addresses via PIC. Of course, using dbx on applications that link in shared libraries seems to be somewhat of a crap shoot. Typically, you can not look into the shared library (same as on SUN3). However, dbx will also dump core on *startup* sometimes. (Haven't figured out how to avoid this though...)

We had tried -PIC, too. That didn't help. But thanks for the tip anyway. > Of course, using dbx on applications that link in shared libraries seems > to be somewhat of a crap shoot.

May be it *is* crappy on the sun3, but on the sparc we developed xmath where most parts were sharable libraries, and dbx works. What's needed is to build the object file that you want to debug with the -g flag (instead of -pic or -PIC) and then link it into the executable. No special changes to the library needed. We have traced into both our own libraries and X/Motif libraries with no problem. -kam

Motif will write into some variables inside your "shared" library at run time, and as a consequence, the initially shared library will be duplicated by SunOS. You'll have to do better than that. By the way, the split of the library in two is really not necessary. Use -PIC on SPARC instead of -pic. It's in the manual.
