"dlopen(libSDL2_image-2.0.0.dylib, 0x0002): tried: 'libSDL2_image-2.0.0.dylib' (no such file)
I tried the new version: opam pin oplot https://github.com/sanette/oplot.git#0.6
It seemed to install ok:
Do you want to continue? [Y/n] y
The following system packages will first need to be installed:
sdl2_image sdl2_ttf

Let opam run your package manager to install the required system packages?

Done.
Trying the example in utop I get the following:
utop # #use "topfind";;
- : unit = ()
Findlib has been successfully loaded.
utop # #thread;;
utop # #require "oplot";;

Convert to SDL2
sdl1.2 is now very old and minimally updated. It should be relatively easy to convert everything to SDL2.
ld: library not found for -llablgl
I can run the example code in an ocaml shell now
i.e.
#use "topfind"
#thread
#require "oplot"
open Oplot.Plt
let p = plot sin (-2.) 20.
let a = axis 0. 0.;;
display [ Color red; p; Color black; a ]But if I add (libraries oplot) to the dune file of my project, when I dune build I get:
ld: library not found for -llablgl
clang: error: linker command failed with exit code 1 (use -v to see invocation)
File "_none_", line 1:
Error: Error while building custom runtime system
...this is without yet having any oplot (or lablgl) code of my own, just adding the library.
I can #require "lablgl" and open modules from it in an ocaml shell, so it seems installed ok.
Any ideas?
macos: oplot window doesn't close
When I press esc to close the oplot window:
- fps logging stops and it returns to a fresh utop prompt, but the window stays open (and I get 'rainbow wheel' busy mouse pointer if I move it over the window)
- if I look in the task bar there are two items: "XQuartz" and "ocamlrun"
- I can "quit" XQuartz but nothing happens. I have to "force quit" ocamlrun, at this point the oplot window closes (and also utop crashes with "Fatal error: exception UTop_main.Term(-11)")
I've mostly been testing from utop, but same behaviour in ocaml shell.
We tried a few tweaks already, see here #2 (comment) but so far this behaviour persists
Feasibility of headless mode
Hello,
First off; thanks for such a useful package! Plotting with this package feels surprisingly expressive and modular.
Is there any possibility of using the module to create plots in a file (lets say, using the png user device) on a headless machine? i.e. via an ssh shell, or Linux's VT100, etc.
I tried on another machine over ssh recently, but receive this error:
INFO: Loading Sdl_image, Target = linux
INFO: Loading Sdl_ttf, Target = linux
xdpyinfo: unable to open display "".
Can't open display
Can't open display
I assume it's just passing some errors from SDL along, but I haven't read into the internals; just curious about the practicality of this request!
