[news.eclipse.platform.swt] Re: Ubuntu and GMF

[Fedor Isakov <fisakov@xxxxxxxxx>]

Hi Anthony,

this thought has also crossed my mind. I naively tried to substitute the 
libcairo.so.2 on my system with the libcairo-swt.so from Eclipse, 
thinking it could help, but it looks like these libraries are completely 
unrelated and not compatible in any way... Let the linux gurus here 
forgive my ignorance.

Here's what I tried:

 - I ran Eclipse with strace to see where it looks for libcairo.so.2. 
It tries many locations before resorting to /usr/lib, in my case the 
last directory was /usr/lib/jvm/java-1.5.0-sun-1.5.0.08/lib/i386/

 - I put a symlink to libcairo-swt.so into that directory and named it 
libcairo.so.2

 - After all this, any attempts to start Eclipse were unsuccessful.

So, I call the myth that we can substitute Cairo library with the one 
provided with Eclipse debunked. Unless, of course, I did something 
completely wrong, which is quite likely.

Best,
Fedor.
