Undefined reference to:

"std::__1::ios_base::getloc() const", referenced from:
ServerMain(int, char**, bool) in libdatabaselibrary.a(ServerMain.o)
std::__1::basic_ostream<char, std::__1::char_traits<char> >&
std::__1::__put_character_sequ ence<char, std::__1::char_traits<char>
>(std::__1::basic_ostream<char, std::__1::char_traits<char > >&,
char const*, unsigned long) in libdatabaselibrary.a(ServerMain.o)

(etc)

Now, the letter sequence "getloc" does NOT appear in the file
ServerMain.cpp.

How could I figure out what is wrong and where?

Thanks in advance for any hints.

I can only speculate that the 'getloc' resides in a template
implementation (of '__put_character_sequence') which in turn is pulled
in by the compiler when you call some function (like a member of the
'basic_ostream') in 'ServerMain'. Make sure to include all the relevant
libraries for the use of 'basic_ostream'. Since it is likely
implementation-specific, RTFM.

I like Duckduckgo as an alternative to Google.

Thanks. I was using the original gcc in some of my projects/libraries.
Now, that is very difficult to know since llvm is called "gcc" in the
macintosh... I did not notice it.

Thanks again
