Please upload here your config.log file as an attachment file.
We can see that how your configragtion phase were proceeded.

And please describe your build enviromment, version of gnuplot source
ex. Ubuntu 20.04, with gcc, g++-9. gnuplot-5.4.3.

[Pramod Sharma]

Thank you for your reply.
Required details are as follow;
Ubuntu 20.04, gcc 9.4.0, g++ 9.4.0, gnuplot branch-5-4-stable

I have also added "config.log" file. I think there is error related to gcc.

Thanks

Your source is master branch (the development branch (version 5.5) but not branch-5-4-stable.
Your build lacks the preparation of external dependencies.

The easist way to get dependencies for gnuplot on Ubuntu is to use

$ sudo apt build-dep gnuplot

For 5.5, two extra librariles should be installed for webp terminal andLibrary containing Amos routines for complex functions if you need those features.

$ sudo apt install libwebp-dev
$ sudo apt install libopenspecfun-dev
