No package 'pangocairo' found #5

Hi,

I'm using your cairo buildpack together with phantomjs and nodejs buildpacks. Unfortunately, I get the following error on Heroku:

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

Note that I use node-canvas v1.2.1.

Any idea what is wrong here?

Thanks in advance, Michael

I don't think Pango is part of (my) standard build. It's probably time to update the dependencies, so I'll add that into the mix.

mrueegg commented 9 years ago

That would be great. In the meantime, I could downgrade to an older node-canvas version. Which version can you recommend or you know is working with the buildpack?

mojodna commented 9 years ago

I'd guess 1.1.x, but I'm not sure.

Are you using cedar-14 on Heroku? Pango is leading me down a list of other dependencies (fontconfig, harfbuzz) that may not build on the cedar stack as easily.

mojodna commented 9 years ago

...while watching a cedar-14 image being configured, I noticed that pango is part of the base image. You could override PKG_CONFIG_PATH to include /usr/lib/pkgconfig (I think) and possibly pick up Pango support w/o any dependency rebuilds. The easiest way to do this is using heroku bash, setting PKG_CONFIG_PATH, and attempting to install node-canvas.

No, I'm still using cedar-10. Downgrading to node-canvas 1.1.6 helped me to get around this problem. As this version is fine for me, I'll stick with that for the moment. Thanks for your help!

Great. If/when you do decide you want/need to upgrade, try using cedar-14 and report back!
