From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050328 Fedora/1.7.6-1.2.5 Description of problem: Trying to port an OpenMotif/OpenGL application to the x86_64 architecture has thrown up a problem with libGLw. There appears to be something badly wrong internally with this library, such that just linking with it (not even using it) causes an immediate crash. If compiled with the following g++ -g motiftest.cpp -o motiftest -L/usr/X11R6/lib64 -lGL -lXm -lXmu -lXt -lX11 then the sample code runs perfectly. If compiled with libGLW, e.g. g++ -g motiftest.cpp -o motiftest -L/usr/X11R6/lib64 -lGLw -lGL -lXm -lXmu -lXt -lX11 then the sample code crashed within the XtVaCreateManagedWidget call. Version-Release number of selected component (if applicable): xorg-x11-devel-6.8.2-37 openmotif-devel-2.2.3-10 openmotif-2.2.3-10 How reproducible: Always Steps to Reproduce: 1. Compile with g++ -g motiftest.cpp -o motiftest -L/usr/X11R6/lib64 -lGLw -lGL -lXm -lXmu -lXt -lX11 2. Run ./motiftest Actual Results: Application core-dumps within the internals of Xt. Expected Results: It should have created the widget and continued. Additional info:
Created attachment 116640 [details] Sample code demonstrating problem
Same problem occurs on i386. The code works fine using FC2 and FC3.
Yes, openmotif includes a bundled version of libGLw which they have modified in an incompatible way to the "official" libGLw which ships with X.Org. I believe there have been updates released to address this openmotif bug. Reassigning to openmotif component...
Nope, libGLw includes copies of openmotif headers. Assigning back to xorg-x11.

Adding to FC5Target for review.
Has anyone identified what the actual problem is? Does you last comment mean that this will not be fixed for FC4?
(In reply to comment #7) > Has anyone identified what the actual problem is? Yes, see comment #4 above. > Does you last comment mean that this will not be fixed for FC4? It doesn't mean that, but in reality, that is probably true nonetheless. Ultimately, what we'd like to do, is have libGLw and libGLU split out of Mesa sources, as they really should be standalone rpm packages. Then, we'd like to push at least libGLw to Fedora Extras, as nothing in the distribution uses it now. In the mean time, what is needed, is for someone to investigate the libGLw build, remove the private openmotif headers, and restructure the Makefiles or whatever to use the installed systemwide motif headers instead. Then to produce a patch, test it, and commit it to CVS. From there it will go into rawhide for a while to be tested, and then theoretically make it into future FC5 and FC4 updates. However, it is currently a low priority issue right now. It'll get fixed eventually, but wether FC4 is still maintained or not by then is another question. If someone cares strongly about the issue and is interested in doing the legwork and attaches a patch that fixes the problem however, that would seriously speed up the likelyhood of this getting fixed in FC5 and FC4 sooner. There's just too much going on in rawhide right now, and over 200 open bugs in bugzilla against X components, so unfortunately, many issues will sit around for a while based on priority and other factors. Patches certainly welcome though, thanks for asking. ;)
Changing component to Mesa. Need to verify that this is still happening with the latest libGLw.
This report targets the FC3 or FC4 products, which have now been EOL'd. Could you please check that it still applies to a current Fedora release, and either update the target product or close it ? Thanks.
