It turned out this analysis was incomplete and the wxwidgets device also depends on shm_open and shm_unlink so best practice means wxwidgets (when linked as a separate dll in the dynamic devices case) or libplplot (when the wxwidgets code is embedded in that library in the nondynamic devices case) must also be linked with librt for the "Unix but not Mac OS X" case. So I have made that change in commit id 9dfe5bf even though there appears to be no errors discovered in our testing before by not dealing with this potential linking issue for the wxwidgets device driver or libplplot before. So hopefully this second "definitive fix" will finally put this issue to rest. :-) Alan __________________________ Alan W.
