Last updated on OCTOBER 24, 2023

Applies to:

Oracle Solaris Studio - Version Forte Developer 6 Update 2 to 12.6 [Release 6.0 to 12]
Information in this document applies to any platform.


When linking together an application or shared library compiled with the Oracle Solaris Studio/Oracle Developer Studio C++ compiler, the linker flags missing symbols that should be in

Example linker error message:

 Undefined first referenced
  symbol in file
  bool std::operator==<char,std::char_traits,std::allocator >(const std::basic_string&,const __type_0*) ../src/.libs/liblog4cplus.a(fileappender.o)

In the above example, the symbol bool std::operator==<char,std::char_traits<char>,std::allocator<char> >(const std::basic_string<__type_0,__type_1,__type_2>&,const __type_0*) is missing, which is needed by object file fileappender.o. In the example, the fact that an instantiation of std::operator== is missing indicates that the symbol is provided by libCstd.
