How do I setup pngcairo terminal in gnuplot? - gnuplot

Question

I'm having the same problem as this question. I tried installing the libcairo library with the command
sudo yum install cairo-devel
After that, I removed and installed gnuplot through yum. I still get the same error. What else do I need to do to get gnuplot to let me use pngcairo?
I also installed pango through yum.
When I try installing gnuplot from source I get these messages in my config.log:
configure:11776: checking for CAIROPANGO
configure:11784: $PKG_CONFIG --exists --print-errors "cairo >= 0.9.0 pango >= 1.10 pangocairo >= 1.10"
Package pango was not found in the pkg-config search path.
Perhaps you should add the directory containing `pango.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pango' found
Package pangocairo was not found in the pkg-config search path.
Perhaps you should add the directory containing `pangocairo.pc'
to the PKG_CONFIG_PATH environment variable
No package 'pangocairo' found
What exactly do I add to PKG_CONFIG_PATH? I'm not even sure where to find my installed pango and cairo-devel libraries.

Answer 1

pango only provides the runtime libraries. For the development files, you need to install pango-devel:
$ sudo yum install pango-devel
When in doubt about package names, use:
$ sudo yum search foo
where foo is what you are looking for. yum will search in names, descriptions, etc.

Answer 2

libcairo features are available by default in gnuplot 4.4 or later.
The gnuplot44 package can be found in the epel repository: https://fedoraproject.org/wiki/EPEL

Answer 3

Before compile it, install the dependency libraries for cairo-based terminals, like pdfcairo,
sudo apt-get install libcairo2-dev
sudo apt-get install libpango1.0-dev
The full steps to install gnuplot 5.0.1:
Download the source file from here, and then:
#decompress it:
tar -xvf gnuplot-5.0.1.tar.gz
#install the dependency libraries for cairo-based terminals, like pdfcairo
sudo apt-get install libcairo2-dev
sudo apt-get install libpango1.0-dev
#build it:
cd gnuplot-5.0.1
./configure
make
#install it:
sudo make install
