Dear all,
I need to compile libsigc as static program into my appl.So, i
configure such as:
./configure --prefix=/opt/libsigc++/ --disable-shared --enable-static
But when i use make command, i get the following error:

How can i solve it?
Yours,
Mohsen.
When I try "./configure --disable-shared --enable-static ......;
make" with gcc 4.6.3 there are no compilation errors.
But when I look at the source code of sigc++/signal_base.h and
sigc++/signal.h, I see that it's not correct.
sigc++/signal_base.h contains
#include <cstddef>
which shall declare size_t and ptrdiff_t in namespace std. But
size_t and ptrdiff_t are then used as if they were declared in
global namespace.
Which compiler do you use? I wonder if you are one of the first
persons who try to build libsigc++ with a compiler and a standard
library that don't declare data types in more namespaces than
required.
(I think it's like this: <cstddef> must declare size_t
and ptrdiff_t in namespace std and may also declare them in
global namespace. <stddef.h> when included in a C++ program, must
declare size_t and ptrdiff_t in global namespace and may
also declare them in namespace std.)
You can try changing
#include <cstddef>
in sigc++/signal_base.h to
#include <stddef.h>
and see if you can build libsigc++.
It would be fine if you could file a bug report. I think a fix in
libsigc++ is needed.
Do you know that the LGPL license restricts your rights to link
libsigc++ statically? I don't know all the details. Check with the
long license text, if in doubt. I think that if you link statically,
your resulting program or library must be released under the GPL or
LGPL license.
