Hi Leo: Is this a general problem which will always be seen (say if you run ctest or the test_noninteractive target) or a problem that only occurs for special circumstances? If it is special circumstances, than we should update our test suite (ctest and the test_noninteractive and test_interactive targets) to have at least one test which uses those circumstances. The rest of this post is directed to everybody on this list with access to Mac OS X. I strongly urge you to install both the pango/cairo development libraries and the Qt development libraries and do regular testing with the test_noninteractive (or ctest) and test_interactive targets for the svn/trunk version of PLplot. The combination of the cairo and qt device drivers produces excellent results for a large variety of noninteractive plot file formats and also for interactive plots so Mac OS X users are beginning to use those device drivers more and more. This recommended on-going testing effort is just to make sure that the majority of errors for our svn/trunk version and cairo and qt devices get discovered immediately on Mac OS X rather than much later by our Mac OS X users after we make a release. Leo mentioned in an earlier plplot-general thread that it was too time consuming to compile Qt on Mac OS X. However, I don't believe compilation is required in this case. According to http://qt.nokia.com/downloads, there is an SDK version available for Mac OS X. When I tried the corresponding Linux 64-bit SDK, it was a binary with no need to build so I presume that is also true of the Mac OS X SDK. If Leo or anybody else here will confirm that, I will go back and respond to that earlier thread on plplot-general so our Mac OS X users don't get unnecessarily intimidated about installing Qt. You do need lots of disk space for the SDK downloads and the corresponding installed libraries and uncompressed data associated with those libraries. But that is typically less disk space than the 2GB used to store the plots that are produced with "make test_noninteractive". Hopefully none of those lurking on this list are squeezed for disk space in any case since you can buy 500GB to 1000GB of additional disk space now for ridiculously small cost.
