Unable to load graphics library [Cairo is required] [message #464388]

Tue, 22 November 2005 11:44

Eclipse User

I am using Eclipse 3.1.1 on Suse Linux 10 which appears
to have Cairo 1.0.0-7.2 installed. When trying some example
from the GMF project I get the following error. Seems like
and SWT related problem but I have no idea where to start
investigating. Any help would be appreciated.

Thanks,

Tas.

The advanced graphics support in SWT 3.1 requires cairo 0.4,
as cairo 1.0 was not yet out. Sorry for the confusing error
message. The fix is to update to a 3.2 development release
which works with cairo 1.0.

Thanks for the help. I've got it all working under 3.2 now. No need to
apologise for the error message, it was good enough.
