Not installing on Ubuntu 11.04

[adamjv90]

From a clean install this was my prep:

sudo apt-get install build-essential
sudo apt-get install libssl-dev
sudo apt-get install libcairo2-dev libjpeg8-dev

also install most current version of node and npm exactly how instructions tell you to.

when trying to install i get this:

See #109 (Whoops too quick on the draw here as you clearly installed libjpeg8-dev)

[enobrev]

Obviously not a permanent solution, but I found undoing the changes from this commit allows a proper install.

[wallat]

I met this problem on Ubuntu 11.04, too. How to solve it?

[enobrev]

I was wrong. Reverting that specific commit did allow npm to install node-canvas, but it still chokes when trying to use the library as build/default is not there.

Here's what I get when I try to node-waf configure build:

The [9/9] line is in orange.

I'm using node v0.5.8-pre (have tried previous versions back to v0.5.3) on Ubuntu 11.04 (amd64).

[enobrev]

I found the last part of the problem. I reverted to 0.7.2 and then installed via npm. Finally, in node_modules/canvas/lib/canvas.js, it looks for the Canvas objects built from node-waf in build/default on line 12:

var canvas = require('../build/default/canvas')

But the build puts everything in build/Release. So due to time contraints, instead of updating the require in the actual code and potentially breaking other things, I copied build/Release to build/default. That's all it took. Canvas works for me now.

Good luck!

[dominictarr]

this failed for me too, I had to install libcairo2-devel libjpeg8-dev and then I got a new error about gif_lib.h ... installed giflib5 manually http://sourceforge.net/projects/giflib/files/giflib-5.x/
but then got a runtime error: could not find libgif.so.6. This file was actually in /usr/local/lib I just copied it into /usr/lib and now it's working.

It sure would be nice if node-canvas bundled it's deps or you could put them on npm or something.

[rvagg]

The problem with the deps here is that they are huge. You've seen the complaints about the leveldown compile time, that's nothing compared to the problem scale here.

What we ought to do is experiment with getting it all bundled with node-pre-gyp so we can distribute platform - suitable binaries. Glibc versions on Linux make it tricky but arguably it's Linux users that have the easiest time installing deps and compiling anyway.

[LinusU]

Closing this since we aren't using node-waf anymore...
