Cairo "Could not find libpng in the pkg-config search path"

Question

I'm trying to install GTK-DFB and cairo is a requirement. When I try to build it from source, it throws:

checking for cairo's PNG functions feature... 
configure: WARNING: Could not find libpng in the pkg-config search path
checking whether cairo's PNG functions feature could be enabled... no
configure: error: recommended PNG functions feature could not be enabled

Ideas?

Thanks

For me it helped to export the following variable in the shell:

export png_REQUIRES="libpng"

This worked for me. `png_REQUIRES="libpng" ./configure` – Nels Sep 16 '22 at 17:52

You need to have the libpng development packages installed; Installation is distribution dependent, but for debian derivatives following should be enough:

apt-get install libpng12-dev

I think on fedora, the package is called `libpng-devel` – azatoth May 29 '10 at 00:28

If you're on Ubuntu, another much faster solution is to do:

apt-get build-dep gtk+2.0
