Cannot open window, PLPLOT ERROR

[nick-san]

Sorry for horrible English and newbie issue, I need someone's help :(

I have to use this software in university class, but it seems to be won't works well. I've installed gdl-language which is provided by openSUSE official science repository. And I've tried clone this repository and build it, but it also says same error.(maybe something wrong with what I did)

My environment is:

• Thinkpad X13 gen1 (AMD, Ryzen) 32GB RAM
• openSUSE Tumbleweed with all latest packages

Here is error log:

rlysleepynick@x13suse ~> gdl --version

Someone teach me what I should to solve this... Thank you. # #

Self resolved. These errors caused by didn't setting path to plplot colormaps, so I tested this:

cd /usr/share/plplot5.15.0
gdl
window # It works

@nick-san it looks like the plplot library we use in gdl is not well packaged in openSuze. The library should find its (unused by gdl!) palette (.pal) files all by itself. Perhaps adding "/usr/share/plplot5.15.0" in your PATH may avoid the need to 'cd' to this particular directory. It is the 1st time we hear about such an inconvenience. Another possibility is that another software (like the anaconda python installer) has messed with the environment variables, path etc.

I faced the same problem today on my new installation and adding the path /usr/share/plplot5.15.0 to any environment variable does not resolve it for me.

...but what resolved for me was to remove the plplot package with sudo zypper rm plplot and then download and install plplot by hand. After this gdl works normal
