Hi,
thanks for your reply.
I am working on linux plaform to develop the application and then it is
cross-compiled and run on an embedded system with AVR32.
The problem is on the linux platform. I deleted all the libfltk*.so and
libfltk*.a available on /usr/lib or /usr/local/lib.
In attach you'll find the backtrace.
Any comments or help are welcome
Thanks,
Jaws

Hi all,
I have developped an application using the stable version of the fltk
library ver 1.1.9.
Now I need to extend the application using the Unicode character to be
able to use Cyrillic and french characters.
I've noticed the fltk 1.1.6 utf8 version but compiling it with my app
there are some incompatibility in some functions (for example awake
function).
So I've started to thing to pass to the 1.3 version or 2.0. I am
newbie on fltk (only 1 year of experience). What are the main
differences beetween the two main versions?
FLTK 2.0 is an experimental, non-stable, but also a working version. You
should only use it, if you are willing to accept API changes and other
instabilities during your use.
FLTK 1.3 is the official, upcoming stable version that will preserve API
compatibility at a high level. Support is (IMHO) much better than for 2.0.
What is the best choice having an application working on fltk 1.1.9 to
integrate the utf8 characters?
FLTK 1.3 is almost API compatible with 1.1, and therefore it is the best
way to go and test it without code modifications (almost). There's a
chapter about migration in the docs, where you can see what changes you
can expect.
Building the last snapshot fltk 1.3.x-r6649, my application exit with
a segmentation fault. Even trying to debug the code it is not clear
the cause of this anomaly.
That's strange and should not happen. The most probable reason is that
you may have some old (1.1) .dll (Windows) or .so (Linux) files that you
are using together with your 1.3-compiled code (the shareable libraries
have the same names, so this may happen unintentionally), but they are
not binary compatible.
Any suggestions? Any comments or idea are welcome.
Check your installation, link statically, maybe with explicit use of
FLTK 1.3's fltk-config, clean your old installation, ...
On which platform are you developing? Can you run the FLTK 1.3 demo
programs?
