The build error mentioned in the compilation log is trivial to fix, GCC
even tells you what to do: Get rid of the default parameter in the
function definition, as done in the attached patch for the mentioned
occurrence and an additional one (default-arguments-in-definition.patch).
However, the compilation with GCC 4.9 fails at a second point, too. This
is due to bug #61659 in GCC
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61659). I've attached a
workaround for this problem (gcc-4-9-workaround.patch) - in case you
don't want to wait for the GCC guys to fix the bug (it sounds
complicated, could take a while, they've been fumbling for 2 months now).
With those 2 patches applied, sofa-framework-1.0~beta4 compiles fine
with gcc 4.9.
Cheers,
Martin
Description: No default arguments in function redeclaration
Compilation fix: Default arguments for function parameters are only
allowed in the original function declaration, not in redeclarations
(like the definition of functions that have already been declared).
They are unnecessary anyway because the default parameters have
already been set in the function declarations.
