Yes, it is clearly not a hardware problem, but trying for the linux environment - The failure reported in (my non GUI) Linux system is - jkt@set1:~$ ja JVERSION Engine: j807/j64nonavx/linux Release-a: commercial/2019-01-11T11:06:44 Library: 8.07.22 Platform: Linux 64 Installer: J807 install InstallPath: /usr/local/lib/j64-807 Contact: www.jsoftware.com load 'plot' 'surface' plot +/~ 1 o. i: 6j99 Unable to init server: Could not connect: Connection refused Cannot parse arguments: Cannot open display: ts '' 2019 1 17 19 22 17.938302 host 'ls -lrt ~/Documents/jstuff/j64-807-user/temp' total 4100 -rw-rw-r-- 1 jkt jkt 2839960 Jan 11 08:15 libj-nonavx.so drwxrwxr-x 2 jkt jkt 4096 Jan 14 09:35 je_update -rw-rw-r-- 1 jkt jkt 1347264 Jan 17 19:22 plot.pdf But, as shown above, the .pdf file is created there anyway. This also happens in the NaN error situation in Darwin - the PDF output file is created, then the error occurs. So, I have to think that things go into the weeds between the creation of the PDF file and the launch of the Preview display. Turning on debug causes a change that avoids the problem. A similar thing, but different error, happens in Raspberry Pi jkt@RPi-3-64:~/Downloads$ ja JVERSION Engine: j807/j32/raspberry Release-a: commercial/2019-01-12T05:54:03 Library: 8.07.22 Platform: Linux 32 Installer: J807 install InstallPath: /usr/local/lib/j807 Contact: www.jsoftware.com load 'plot' plot ?~9 sh: 1: : Permission denied ts '' 2019 1 17 20 11 46.271807 host 'ls -lrt ~/Documents/jstuff/j807-user/temp' total 2724 -rw-rw-r-- 1 jkt jkt 2686633 Jan 14 05:39 libj.so drwxrwxr-x 2 jkt jkt 4096 Jan 17 19:37 je_update -rw-rw-r-- 1 jkt jkt 94704 Jan 17 20:11 plot.pdf This also happens when running j in a GUI on the Pi. Even though I rarely/never use the GUI interface, I should figure out what the permissions problem is so that I could do plots in that environment. Hope this is helpful to find the culprit. - joey > On 2019Jan 17, at 14:51, bill lam <bbill....@gmail.com> wrote: > > initiate a debug session first by > dbr 1 > > and then run the surface plot, when it suspended , the values of y and Tfm > can examined. > > > On Fri, Jan 18, 2019, 2:45 AM Joey K Tuttle <j...@qued.com wrote: > >> In my various rambles, I made this point. >> >> iMi7:bin jkt$ ja >> JVERSION >> Engine: j807/j64nonavx/darwin >> Release-a: commercial/2019-01-11T11:44:43 >> Library: 8.07.22 >> Platform: Darwin 64 >> Installer: J807 install >> InstallPath: /applications/j64-807 >> Contact: www.jsoftware.com >> load 'pacman' >> 'update' jpkg '' >> Updating server catalog... >> Local JAL information was last updated: 16 Jan 2019 08:14:56 >> All available packages are installed and up to date. >> >> load 'plot' >> plot ?~9 NB. trivial plot >> NB. resulting PDF displayed by Preview was blank >> >> 'surface' plot +/~ 1 o. i: 6.28j99 NB.
