Hi, thanks for reply.
I use your fix, and now give me this error:

I try:
~olena-2.0/_build/scribo $ make

And get this:

        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.
