I'll update PDL-Graphics-PLplot as necessary. I saw your commit of the revised example 2 for Perl/PDL. Since then I have made some build-system changes (revision 9037) to change the list of what Perl/PDL examples are executed depending on the CMake variable HAVE_PDL_GRAPHICS_PLPLOT_40. Currently, example 02 and example 20 are excluded from the list if that variable is not "ON". Could you follow up on my work by maintaining the two lists in plplot_test/test_perl.sh.in as you continue to update the perl/pdl examples and add new ones? Also, could you put some basic cookbook-style instructions in examples/perl/README.perldemos so a perl newbie (like me) could download and install PDL-Graphics-PLplot-0.40? I would like to test out your updated examples. (My current installed version of PDL is 2.4.3-8 from Debian Lenny.) The current method of specifying HAVE_PDL_GRAPHICS_PLPLOT_40 is to set either -DHAVE_PDL_GRAPHICS_PLPLOT_40=ON or -DHAVE_PDL_GRAPHICS_PLPLOT_40=OFF (the default) as one of the cmake options. I would like to replace that crude control method by one that automatically tests the version of PDL-Graphics-PLplot that is available and sets HAVE_PDL_GRAPHICS_PLPLOT_40 appropriately. To implement that, I need to know a simple command you could execute from the command-line that could be used to figure out whether version 0.40 (or later) of PDL-Graphics-PLplot is installed or not. Do you have such a command to suggest to me? Ideally, the command would succeed (return code 0) or fail (non-zero return code) depending on whether 0.40 or later was installed, but other possibilities (such as returning a version number and letting CMake decide whether that is >= 0.40) would work as well. I am very pleased to hear that you are actively working on the Perl/PDL aspects of PLplot again. Alan __________________________ Alan W.
