How do you build it? In your code I see you are also targeting OSX, so that doesn't seem to be the problem. I was trying to use the MacPorts version of libclang3.1 without having set any special compiler flags. So, I am not entirely sure whether it is build correctly. Any hints are appreciate.

At the risk of sounding foolish, is it possible to write the Makefile to use a particular (and configurable) glibc, rather than the glibc that just happens to be on a machine? That way one could use whatever machine, and say "use glibc 2.11". frank >> you will can find out the last version of GLIBC on your distro by running >> strings /lib/libc.so.6 | grep GLIBC >> >> >> On 2013-01-22, at 17:41, Tudor Girba <tudor(a)tudorgirba.com> wrote: >> >>> For example: >>> >>> curl http://pharo.gforge.inria.fr/ci/script/ciPharo20PharoVM.sh | sh >>> ./vm.sh >>> >>> or: >>> >>> curl http://pharo.gforge.inria.fr/ci/script/ciPharo20CogVM.sh | bash. >>> ./vm.sh >>> >>> Cheers, >>> Doru >> >> > > > > -- > Best regards, > Igor Stasenko. >

But then, what if tomorrow we will use something else than cairo? In the long run, i think, using libpng directly will be more reasonable.

Hi Mark, Should have read the man page for open instead of a web page. I had already tried the second version. Still crashes though, with the same error, on 10.6.8 (can try it on newer and older versions too, after finding a working version) Mariano: CogVM-sandard also has the illegal instruction Stephan

If your application works extensively with external images It is important. That's why I write question at user group about how to get Form efficiently from external memory which filled by FFI call.
