With my latest changes I think I have complete (at least as far as ctest is concerned) success for Linux visibility testing done with export CC='gcc -fvisibility=hidden' export CXX='g++ -fvisibility=hidden' export FC='gfortran -fvisibility=hidden' As of revision 8879 here is what I get now: 1/ 17 Testing examples_c Passed 2/ 17 Testing examples_cxx Passed 3/ 17 Testing examples_f77 Passed 4/ 17 Testing examples_f95 Passed 5/ 17 Testing examples_java Passed 6/ 17 Testing examples_octave Passed 7/ 17 Testing examples_python Passed 8/ 17 Testing examples_tcl Passed 9/ 17 Testing examples_perl ***Failed 10/ 17 Testing examples_ada Passed 11/ 17 Testing examples_ocaml Passed 12/ 17 Testing examples_psttfc Passed 13/ 17 Testing examples_png Passed 14/ 17 Testing examples_svg Passed 15/ 17 Testing examples_pscairo Passed 16/ 17 Testing examples_pngcairo Passed 17/ 17 Testing examples_compare ***Failed Here are details of the comparison test: c++ Missing examples : Differing examples : f77 Missing examples : Differing examples : f95 Missing examples : Differing examples : java Missing examples : 19 Differing examples : octave Missing examples : 19 Differing examples : python Missing examples : 19 Differing examples : tcl Missing examples : 19 Differing examples : 11 13 15 16 20 perl Missing examples : 21 22 23 24 25 26 27 28 29 30 Differing examples : 02 08 20 ada Missing examples : Differing examples : ocaml Missing examples : Differing examples : The above result is as good as it gets for ctest these days. The perl problem is caused by the external PDL/plplot project that is distributed with Debian testing (version 1:2.4.3-6+b1) being far behind what libplplot provides as an API these days. I don't know if Doug Hunt has addressed this issue yet for later releases of PDL (if any). However, it does seem that until the API issues were encountered for example 20, everything was working reasonably well for perl/pdl in terms of visibility. I am keen on minimalism so for my next PLplot step (later today) I hope to remove all the redundant (I think) macro use in the various device driver source code files since that is dealt with by drivers.h. Also, I may get a chance today to test the case when dynamic devices are disabled. But that case has already been tested on Windows so I may be close to being done with my contribution to visibility testing/debugging on Linux. Now to bring up a different, but related topic. Werner, do you know the Windows library call (or calls) to dynamically load plug-ins? If so, I think basically all you have to do to implement dynamic drivers on Windows is replace the libltdl calls (lt_dlinit, lt_dlopenext, lt_dlsym, and lt_dlexit) in src/plcore.c and drivers/get-drv-info.c by the equivalent Windows library functions for the #if defined(WIN32) case. So long as you know how to dynamically load on Windows, I don't think this will be a particularly time-consuming project, and it really is time for the Windows version of PLplot to get access to this nice feature that all the Unix developers and users enjoy. If you do decide to attempt to make dynamic devices available on Windows, then I believe from my tests today that you are unlikely to encounter any Windows import/export/visibility issues for those devices.
