Sorry for taking so long to get back to you; emails about compilation
problems will probably get answered quicker on the development mailing
list...

But maybe, the problem come from the new libs version ?
Is there anyone who can run the last CVS on a Linux ?
Yes, I've been running it since I did the library conversion.
And what is his lib versions ?
gtk+-2.0 = 2.4.3
gobject-2.0 = 2.4.2
gmodule-2.0 = 2.4.2
glib-2.0 = 2.4.2
pango = 1.4.0
gtkmm-2.4 = 2.4.4
gdkmm-2.4 = 2.4.4
glibmm-2.4 = 2.4.3
pangomm-1.4 = 2.4.4
I don't know if it can help but when I run the "ddd
inkscape", it gives me :
Program received signal SIGSEGV, Segmentation fault.
SPDesktop::_layer_hierarchy_changed(SPObject*, SPObject*, SPDesktop*)
(top=0x84023d0, bottom=0x84023d0, desktop=0x86bc208) at stl_list.h:397

void SPDesktop::_layer_hierarchy_changed(SPObject *top,
SPObject *bottom,
SPDesktop *desktop)
{
desktop->_layer_changed_signal.emit(bottom);
}
That place for the crash looks a little strange to me. Could you try
compiling without optimization and see if it yields the same backtrace
(and give me some more of the actual backtrace as well..).
The only reason I can think of that it would crash here is if
SPDesktop::_layer_changed_signal were not initialized properly for some
reason.

Sorry ... i'm a real beginner in C++ programming :/
how can I compile without optimization ?

Probably the easiest way is to rerun configure, setting the CXXFLAGS
environment variable beforehand, like:
CXXFLAGS="-g" ./configure
Then run make as before.

Sorry ... i'm a real beginner in C++ programming :/
how can I compile without optimization ?
I've just find the -O0.
so I compiled like this :
export CXXFLAGS="-g -O0"
make clean
./configure --disable-mmx
make
Is it the correct way ?
Now here is the gdb message:

That is fine.
Now here is the gdb message:

628 empty() const { return _M_node->_M_next == _M_node; }
So, this is different without optimizaiton...
Most of these are inline functions, so any information about them is
normally stripped away by the optimizer.
(In general the optimizer may rearrange the code in ways that do not
correspond to the source code.)
And the backtrace :
(gdb) backtrace
#0 0x080ede58 in std::list<sigc::slot_base,
std::allocator<sigc::slot_base> >::empty() const (this=0x8) at

at signal.h:616
It would seem that sigc++ is dereferencing a NULL pointer. To the best
of my knowledge, emitting an unconnected signal (having a NULL impl)
should be harmless (sigc++ should check the pointer).
This sounds like a sigc++ bug.
and libsigc-2.0 : 2.0.2
Try upgrading to 2.0.3, which is the version I have.

Yes, the compilation is running !
And now I see that there's some good changes since my last
compilation...really good !

Okay, I've altered configure.in to require 2.0.3 or later.
