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.
