This is a // placeholder used while constructing an object, and the function // should never actually get called. There is a default // implementation in libsupc++ but that has dependencies on I/O // and so on, unwanted in a minimal eCos environment. Instead we // want a minimal __cxa_pure_virtual(). // //####DESCRIPTIONEND#### // //========================================================================== #include #include extern "C" void __cxa_pure_virtual(void) { CYG_FAIL("attempt to use a virtual function before object has been constructed"); for ( ; ; ); } // EOF pure.cxx
