Undefined Reference Error When Compiling Wont go Away?


Assuming you are using GNU make.

You didn't specify any link rule in your makefile, and the implicit link rule is:

$(CC) $(LDFLAGS) n.o $(LOADLIBES)
$(LDLIBS)

where n.o is your object files. Further; the GNU linker requres that library names come after the object files that are supposed to link against those libraries, so if you change your LDFLAGS to LDLIBS then it may fix your problem.

It'd be useful if you post the actual link command that your makefile attempts to execute (so we can verify that this implicit rule is being used). Of course you could write your own link rule instead of relying on the implicit rule.

Undefined Reference to member function (false unexpected error)
You forgot to compile and link Ship.cpp I can tell this because if you'd tried to compile it then you'd have got an error here: virtual void func()=0; virtual void mov()=0; That's not valid C++, you don't define pure virtuals like that (you don't need to define them at all unless they are destructors or you call them explicitly) If you don't link with the file with the definition of Ship::get

Linker Error: Undefined reference / bad reloc address / ld returned 1 exit
Apparently you didn't define the constructors for Player: Player(); Player( const char [], int, int, int ); Add at least stub definitions like this: Player::Player() { } Player::Player( const char [], int, int, int ) { }

Mysterious linker error "undefined reference to `__gxx_personality_v0'" using clang in cygwin
OK, as I was further wandering around the web, I found a relevant post, see nos's answer. So I realized I was compiling with Cygwin64 terminal, while Cygwin's clang port is a 32 version. After switching to the Cygwin32 terminal, everything works fine.

Error: Call to a possibly undefined method crearNotaS through a reference with static type Class
ActionScript is an object oriented Language. Classes are supposed to be objects too and when you want to access their methods you either need to make an instance of them first or make sure the target function is of type "Static", which has limitations of its own. This is all about core concepts which you need to know before running your code. I suggest taking a look at some tutorials about classes

undefined reference to `ERR_load_crypto_strings'
As answered on the maillist by scott_n but for the record here, swap the order to -lssl -lcrypto. Explanation: for static C libraries in general on nearly all systems, members of library files like libxxx.a are only pulled in by the linker if they define things referenced from translation units already linked i.e. to the left in the command line. OpenSSL libssl has (numerous) references to libcry
