*** Warning: linker path does not have real file for library -lsupc++.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libsupc++ and none of the candidates passed a file format test
*** using a regex pattern. Last file checked: /usr/lib//libsupc++.a
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.
