set terminal png #1

Closed jtrmal closed 8 years ago

jtrmal commented 8 years ago

The options f4de generates for gnuplot assume the png terminal will be provided by libgd. When png terminal is provided by libcairo, this command from the makefile will ends up with an error:

gnuplot> set terminal png truecolor medium size 800,800 crop
Terminal type set to 'pngcairo'
                                    ^
         unrecognized terminal option

which linux distribution are you using ?

jtrmal commented 8 years ago

$ cat /etc/*-release CentOS release 6.7 (Final) Cluster Manager v7.1 slave LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch CentOS release 6.7 (Final) CentOS release 6.7 (Final)

We have gnuplot provided via the "modules" so I'm not sure if the gnuplot is from the distribution $ gnuplot --version gnuplot 5.0 patchlevel 0

I will test it using a CentOS 6.7 VM, in the meanwhile if you can use a docker, look at https://hub.docker.com/r/martialnist/docker-f4de/

I actually gave up and installed my own gnuplot -- for a user having no control about the OS or the packages,this was probably the most straightforward path. y.

I actually think that even an error message would be fine, assuming it would be to the point:

Error: gnuplot binary exists but the png terminal is not supported and Error: gnuplot binary exists but the png terminal does not support the necessary options (you probably have libcairo png terminal instead of libgd png term)

or something like that. y.

One thing I am unclear is that the terminal type should have been 'pngcairo' (not png). I have added a check for libgd's PNG support in the make mincheck which should now exit with error unless it is installed and available to gnuplot.

jfiscus commented 8 years ago

Pngcairo was a more function png library.

My impression was that if libgd png teminal will not get compiled in, an alias (or a compatibility layer) will be created using libcairo to act as "png" terminal as well (in addition to pngcairo). However, for some reason it does not support the "medium" keyword (IIRC). y.

Just as a follow up, as I have been trying on CentOS 6.7, if you yum install gd gd-dev before doing the yum install gnuplot, when you run echo 'set terminal' | gnuplot you will see a png line such that PNG images using libgd and TrueType fonts (ie no more dependency on libcairo).

LJHIndustries commented 7 years ago

I had the same issue where png was not being recognized, I installed libgd (below) and then gnuplot again from source:

yum install gd-devel
