I have Ubuntu 11.10 32 bits.
Anyone can help me?
Thanks for your report.
Ubuntu 11.10 provides g++ 4.6.1 which changed few things about
initialization of global structures/classes.
This is a known issue which can be avoided easily.
I have just added a "known issues" section in the download page
explaining the workaround.
You can find it below.
Thanks for your interest in Scribo and Olena.
Sincerely,
Guillaume

Compilation issues may be encountered with g++ 4.6.0 and 4.6.1
(especially on Ubuntu 11.10).
Here is an example of the possible error :
../../../../olena/milena/mln/canvas/browsing/snake_generic.hh:90:29:
error: uninitialized const ‘mln::canvas::browsing::snake_generic’
[-fpermissive]
../../../../olena/milena/mln/canvas/browsing/snake_generic.hh:76:14:
note: ‘const struct mln::canvas::browsing::snake_generic_t’ has no
user-provided default constructor
Many non-relevant warnings may also arise.
A simple solution is to add CXXFLAGS to configure script with the
following argument :
%begin bash%
./configure CXXFLAGS="-fpermissive -Wunused-but-set-variable"
%end%
Otherwise, using a different version of g++ would also fix this issue
without specifying anything to configure.
