[gtkmm] Compiling problems...

[Amit BHATNAGAR <abhatnag mda ca>]

Hi all.

I have GTK+ 2.2.4 installed and I am trying to compile 
glademm-2.0.0.1, on solaris 8. I get the following error:

The following error is occuring in the make of clist.cc  
in glademm 

make[3]: Entering directory
`/export/home/jgg/software/glademm-2.0.0.1/src/writers'
if g++ -DHAVE_CONFIG_H -I. -I. -I../.. -I.. -I../SourceWriter

-g -O2 -MT clist.o -MD -MP -MF ".deps/clist.Tpo" \
  -c -o clist.o `test -f 'clist.cc' || echo './'`clist.cc; \
then mv -f ".deps/clist.Tpo" ".deps/clist.Po"; \
else rm -f ".deps/clist.Tpo"; exit 1; \
fi

#warning This file includes at least one deprecated or antiquated header.
Please consider using one of the 32 headers found in section 17.4.1.2 of the
C++ standard. Examples include substituting the <X> header for the <X.h>
header for C++ includes, or <sstream> instead of the deprecated header
<strstream.h>. To disable this warning use -Wno-deprecated.
clist.cc: In member function `virtual void Gtk_CList::Configure(const
Widget&, 
   CxxFile&, const std::string&) const':

clist.cc:49: (Each undeclared identifier is reported only once for each 
   function it appears in.)
clist.cc:133:2: warning: #warning Fixme for non standard column headers
(internal widgets)

The offending code in clist.cc is:

void Gtk_CList::Configure(const Widget &w, CxxFile &f,const std::string
&instance) const
{  Parent::Configure(w,f,instance);
   std::string column_widths=w.getProperty("column_widths","20");
#ifdef __MINGW32__
   char buffer[column_widths.size()+1];
#else
   char *buffer=(char*)alloca(column_widths.size()+1);
#endif
   memcpy(buffer,column_widths.c_str(),column_widths.size()+1);
   char *stringp=buffer;
   // 2do: Tooltips

any ideas?
