re: Compile a file

I managed to get the sigc++ 1.0 libraries linked when compiling (by 
putting /usr/lib path in ld.so.conf I think) and tried to compile again 
but still getting errors. I think the cause of it is

/opt/Y-devel/include/Y/c++/object.h:30:27: sigc++/sigc++.h: No such file 
or directory
In file included from /opt/Y-devel/include/Y/c++.h:28,
                 from temp.cc:2:

I can't find any sigc++.h in sigc++ 1.0

I assume I should be only using sigc++ 1.0?
