Arjen, Further testing with ifort and old versions of gfortran has also lead to problems with my original implementation of plunicode using kind. I've followed your recommendation and it seems to work more reliably on the compilers available to me.

I've also reproduced this now on an 64 bit machine running Ubuntu Hardy. A 32 bit machine with the same version of Ubuntu on does not give the error. The problem is in the final page of example 19 - I assume it is in the calls to plmap / plmeridian using mapform19. Hopefully this might help track it down.

[Plplot-devel] Plplot examples and ifort
I've been testing the fortran examples using a rather old version of ifort (8.1) on 64-bit linux. In order to get the examples to compile and run I encountered two issues 1) Example 20 requires the -assume byterecl flag to ifort in order to get byte length records. Otherwise reading lena.pgm fails with an error. This is in accord with the comment in the example. 2) Example 21 requires the -O0 flag, otherwise the compiler optimises away the test (x.ne.x) in the function myisnan. For 1) it would be nice to automatically add this option if ifort is detected. For 2) the flag to turn off optimisation is a bit of a fix. ifort does have an isnan intrinsic (along with many other compilers) which we could use instead. This requires some extra cmake logic though. Any suggestions? After these two changes I get the following with ifort 8.1 (64-bit) f77 Missing examples : 26 Differing examples : 20 21 23 f95 Missing examples : 24 25 26 27 Differing examples : 20 21 With gfortran 4.1 on the same machine I get f77 Missing examples : 26 Differing examples : 20 23 f95 Missing examples : 24 25 26 27 Differing examples : 20 For example 21, some of the differences are just rounding errors. I do however see some additional line at the end like. This is from plot3d. I also see similar extra lines from the java and octave versions on a different machine, so again I suspect a rounding error.

Re: [Plplot-devel] [Fwd: [ plplot-Bugs-2040815 ] cairo driver does not clip plpoin symbols outside viewport]
I responded to this on the SF site, but it looks like the response did not get forwarded to the list. The issue is only that text clipping is not used by default with the cairo drivers as it made them much slower. -Hazen On Aug 11, 2008, at 3:29 AM, Arjen Markus wrote: Hello, can someone have a look at this particular issue?

[Plplot-devel] Wishlist: a verbose testing option
On 2008-08-11 14:43-0600 Orion Poplawski wrote: > Wishlist: a verbose testing option that > would output the actual command executed for each test. I get a similar result "by hand" by, e.g., putting the command echo $index inside the shell loop in plplot_test/test_ada.sh (or any of the other scripts in that directory if a problem occurs for a different language). But you are right, there should be a plplot_test.sh option passed to the various plplot_test shell scripts to echo the command line automatically (rather than just echoing the index as above). Such an option would work in the install tree where you are running plplot_test.sh directly, and we could automatically use the suggested plplot_test.sh --verbose option whenever we run ctest. (Note, the plplot_test.sh --verbose output will only show for that case if you invoke the --verbose option for ctest which is exactly what we want.) I will implement this idea soon.

So what happens if you simply use FC='ifort -assume byterecl' ? If that works for all examples without messing them up, then perhaps we should recommend that ifort option in the wiki along with an explanation that example 20 requires byte-length records. That seems simpler to me than detecting ifort and fooling around with a special compile option for example 20 for that compiler. However, I don't feel strongly about it so do what you think is best. (2) I think your idea of detecting whether the isnan intrinsic is available is a good one since -O0 does seem like a workaround. Most of the work is already done using the CheckFortranFunctionExists.cmake file for CMake-2.6.0 (which I know about since I wrote the first version of it for the FreeEOS project). For now, we can simply copy that file from CMake-2.6.0 modules to our cmake/modules directory so that those with 2.4.8 can still use PLplot. > > After these two changes I get the following with ifort 8.1 (64-bit) > > f77 > Missing examples : 26 > Differing examples : 20 21 23 > f95 > Missing examples : 24 25 26 27 > Differing examples : 20 21 > > With gfortran 4.1 on the same machine I get > > f77 > Missing examples : 26 > Differing examples : 20 23 > f95 > Missing examples : 24 25 26 27 > Differing examples : 20 > > For example 21, some of the differences are just rounding errors.
