apt install libplplot-dev, but I experience the problem reported in issue 6 Yep, `sudo apt-get install libplplot-dev` worked fine. Thanks ! I don't experience the problem reported in issue 6, perhaps because I'm trying to install version 0.74. The PLplot.so loads without any problem - but there are some test failures (including a segfault): `Test Summary Report ------------------- t/plplot.t (Wstat: 139 Tests: 15 Failed: 0) Non-zero wait status: 139 Parse errors: No plan found in TAP output t/plplot_library_tests.t (Wstat: 1024 Tests: 210 Failed: 4) Failed tests: 69, 71, 124-125 Non-zero exit status: 4 Files=3, Tests=225, 42 wallclock secs ( 0.08 usr 0.01 sys + 18.27 cus +r 2.41 csys = 20.77 CPU) Result: FAIL` [download] As regards t/plplot.t: $ perl -Mblib t/plplot.t ok 1 - An object of class 'PDL::Graphics::PLplot' isa 'PDL::Graphics:: +PLplot' ok 2 - Simple line plot ok 3 - Simple line plot with LINEWIDTH specified ok 4 - Symbol plot ok 5 - Lines and symbols ok 6 - Sample layer statistics plot ok 7 - Setting pagesize ok 8 - Line plot with gaps (plgapline) ok 9 - Setting JUSTify = 1 ok 10 - Printing text inside and outside of plot window ok 11 - Colored symbol plot with key ok 12 - Colored symbol plot with key: reverse rainbow ok 13 - Colored symbol plot with key, via low level interface ok 14 - plgvpd call works correctly ok 15 - plgvpw call works correctly Segmentation fault (core dumped) [download] Not sure how many tests t/plplot.t wants to run (no_plan), but `ok()` gets called more than 15 times. At least the module is installable .... and usable, unless you want to utilize any of the features that are failing/segfaulting. Cheers, Rob	[reply] [d/l] [select]

PDL::Graphics::PLplot 0.75+ fixes the segfault. It was caused by the return value of plAllocGrid (supposed to be a pointer) et al having PDL Pars type "int", which on 64-bit Linux is only 32 bits. With this being changed to an "indx", it then works.	[reply]

Issue 6 was "couldn't find c_plshade1". This was because plplot 5.14.0 deprecated it, and modern packagers don't add the flag to enable deprecated code. PDL::Graphics::PLplot 0.75+ uses the updated API and doesn't have this problem now.	[reply]
