Hi Igor, I tried the version 0.1.3 on OSX, using the VM you suggested, in a 1.4 image (the one used by Moose). AthensCairoSurfaceExamples example1. complains that the function is not available. The error has been raised by NBFFICallout. Is there something obvious I am missing?

Re: [Pharo-project] direct object manipulation

by Fernando Olivero

Here's an extract of an email i've sent to the list when i successfully used Cairo on Mac. How is Roassal being rendered now? Using FormCanvas? If you have some screenshots would be nice. Saludos, Fernando pd: Regarding the build, after a lonnnngg series of errors, i also managed to build universal binaries of Cairo, using MacPorts (brew just doesn't ease the task of creating 32 bit libraries). sudo port cairo +universal, worked for me, taking at least 30 min to build. ATTENTION: Before entering the port cairo install command, I've had to manually install appleGcc4.2, found @ [1] (file name gcc-42-5666.3-darwin11.pkg. Given that i have Lion, XCode4.2, and if you just allow macports to build appleGcc4.2, it will run a process that consumes resources and finally stalls your computer! I've attached a screen shot that may help somebody else, for setting up the examples. Using NativeBoost Cog VM for Mac, downloadable from NativeBoost site or Jenkins. Great work Javier, and Igor! I'm looking forward to implement a Text editor using Cairo+Pango + "my new morphic".
