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.
