Description Mamoru TASAKA 2008-01-31 05:46:08 UTC 
Description of problem:

Now rawhide (dist-f9) switched to gcc43.
I tried to rebuild by package jd with gcc43, but it failed with
many messages like:
------------------------------------------------------------------------
/usr/include/sigc++-2.0/sigc++/signal.h:1665: error: declaration of 'typedef
struct sigc::slot_list<sigc::slot<T_return, sigc::nil, sigc::nil, sigc::nil,
sigc::nil, sigc::nil, sigc::nil, sigc::nil> > sigc::signal0<T_return,
T_accumulator>::slot_list'
/usr/include/sigc++-2.0/sigc++/signal.h:158: error: changes meaning of
'slot_list' from 'struct sigc::slot_list<sigc::slot<T_return, sigc::nil,
sigc::nil, sigc::nil, sigc::nil, sigc::nil, sigc::nil, sigc::nil> >'
--------------------------------------------------------------------------
Perhaps there must be some need to fix jd side, however
would you fix libsigc++20 side first?

I'll check with Murray on his release plans.

It seems that #undef ing SIGC_TYPEDEF_REDEFINE_ALLOWED in 
%{_libdir}/sigc++-2.0/include/sigc++config.h works (and actually
for compiling jd this works: 
http://cvs.fedoraproject.org/viewcvs/*checkout*/devel/jd/jd.spec
http://koji.fedoraproject.org/koji/taskinfo?taskID=401135 
)
Comment 3 Mamoru TASAKA 2008-02-07 17:43:31 UTC 
It seems this is fixed in 2.0.18-3.fc9 (actually in sigc++config.h
now SIGC_TYPEDEF_REDEFINE_ALLOWED is not defined)
