First install Gnuplot on Big Sur:
If you have MacPorts (https://www.macports.org/) installed then update it:
sudo port -v selfupdate
If you do not have MacPorts installed then you can install it by opening the following URL:
Install gnuplot using MacPorts:
sudo port install gnuplot +wxwidgets
(I like the wxwidgets API)
$ gnuplot
gnuplot> plot sin(x)
We should now see a nice little sinusoid graph.
Now let's build Gnuplot/C :
$ cd gnuplot_c/src/
$ make -f makefile.macos
$ cd gnuplot_c/src/
$ make -f makefile.macos
Now let's test Gnuplot/C :
$ cd gnuplot_c/examples/
$ ./br.sh LinesAndPoints
$ cd gnuplot_c/examples/
$ ./br.sh LinesAndPoints
We should now see the graphs plotted.
Note, if you see the following message:
sh: /dev/nul: Permission denied
Then you need to do the following:
$ sudo mknod /dev/nul c 1 3
$ sudo chmod 666 /dev/nul
Now let's test Gnuplot/C again:
$ ./br.sh LinesAndPoints
Excellent. All running nicely :-)
