Hi all,

I am trying to build Pango with Cairo support on Linux (Fedora Core 4). I already built and installed Cairo in my machine. I also exported PKG_CONFIG_PATH variable to the package and config as below. As output code below, I think Pango already found where Cairo is but just after it tell that it can't find some function in the library. I don't understand why. I check by hand in the Cairo libray and these functions did exist.

Please save your time and have a look the code and give me an advise.

Thanks and best regards,
Tuan Phan

What versions of pango and cairo are you using? I'm using pango 1.15.6 and cairo 1.3.12.

Running pango 1.15.6's ./configure --help, I don't see any options --with-cairo or --enable-cairo so I don't think those do anything for you. I think pango uses cairo if it's available, and if not, it doesn't.

Maybe you need to tell it where you installed cairo?

I recently started having this problem too:

(which is why I searched for the error message on Google and ended up finding this discussion thread). I did not have this problem compiling pango "normally" on Mac OS X, but as soon as I started trying to make a universal binary (containing both Intel and PowerPC code), I got the above errors. I don't know why it's happening. I worked around it by creating a config.cache file in the root of the pango directory with the following contents:

These values are correct for me; you may need to change the answers to apply to your situation. To use this file, you ./configure pango with the --config-cache option.

If anyone knows why pango isn't finding the cairo functions which really are there, or a cleaner way to work around this without needing a config.cache file, please let us know.
