Hi,
I am building a standalone application using SWT and am trying eclipse
3.2m4 which works fine. However when I try the standalone I get the
following error.
Unable to load graphics library [Cairo is required]
(java.lang.UnsatisfiedLinkError:
/opt/java-libs/lib/3.2m4/libswt-cairo-gtk-3218.so: /lib/libc.so.6: version
`GLIBC_2.4' not found (required by /usr/lib/libcairo.so.2))
Now assuming 3.2m4 is using the same libraries how do I access them for my
application. I am using the -Djava.library.path=/opt/java-libs/lib/3.2m4
switch which worked before. It looks like libc is for the wrong version of
GLibC. Any assistance would be appreciated, I could revert to the earlier
version if necessary but would prefer not.
Thanks
Simon Meaden

Cairo is used for advanced graphics like anti-aliasing, paths, patterns,
transformations. Once you are in advanced graphis mode, all the calls must
be made using the cairo library. If we are not in advanced graphics mode,
GC uses gdk calls.
You will notice in the GC code that the cairo calls are made after checking
if cairo != 0. The use of Cairo is initialized by calling
GC.setAdvanced(true) or by using advanced features such as
setAntiAlias(true).
For example look at GC.drawLine() - with Cario it uses cairo_move_to(),
cairo_stroke() etc otherwise it calls gdk_draw_line().
