external linker error Falls Village, Connecticut

Using dumpbin /exports winscard.lib on the library I've got gives me [email protected] Looks like a c mangle, rather than c++ mangle. :) Turning verbose output on for the link may More details can be found here; Linux ld man page. Pedantically, non-pure virtual functions need be defined (although, as mentioned, some compilers won't complain until you call them, but some will). They don't care about user friendlyness.

Missing some library.[Make sure that all the Libraries are included in "Additional Include Libraries"].2. It can also occur if the name the linker searches for does not match the name of the symbol in the library or object file that defines it. share|improve this answer edited Feb 16 '15 at 8:31 M.M 72k662131 answered Sep 24 '12 at 23:38 Luchian Grigore 167k28295455 1 Further information for "templates must be defined in the So no, I didn't check Intel's compiler recently.

Thus the linker will not see it and doesn't complain. Also, I'm not sure what version of MSVC produced the errors here, but newer versions include the name (both mangled and unmangled) of the function referring to the unresolved external symbol.

If the error message is similar to unresolved external symbol WinMain referenced in function function_name, link by using /SUBSYSTEM:CONSOLE instead of /SUBSYSTEM:WINDOWS. grasp.cpp happens to be a legitimate C file. The content you requested has been removed. I doubt I am linking to an old version of the lib because even when I clean the whole solution, the problem persists. –Danilo Carvalho Apr 11 '13 at 17:35

Verify that the declaration matches the compilation linkage for each symbol. Or if i remembered correctly, type `#use "winscard.lib"` somewhere in the hearder of top the code. I'm wondering why, on the one hand, runtime performance seems so important for you, but on the other hand, MuJoCo uses the same timestep for all objects. If you must separate the implementation, the usual workaround is to have an impl file which you include at the end of the header that declares the template.

To correct this, you can declare a template operator before the Foo type and then declare as a friend, the appropriate instantiation.

Verify that the exported decorated names match the decorated names the linker searches for.The UNDNAME utility can show you the equivalent undecorated external symbol for a decorated name.

Solution 3 Accept Solution Reject Solution Hi,The problem can occur in the following cases:1. However, I do not believe that that declaring the function with __declspec(dllexport) is sufficient to make it unmanaged, but maybe that depends on the compiler version? –jerry Apr 16 '13 at When the linker tries to find the definition of this missing function, it generates LNK2019. The syntax is a little awkward, but is looks as follows; // forward declare the Foo template class Foo; // forward declare the operator << template std::ostream& operator<<(std::ostream&,

For more information about possible causes and solutions for LNK2019, see the Stack Overflow question What is an undefined reference/unresolved external symbol error and how do I fix it?. If you're using MSVS, you'll see that projects generate .lib files. But I don't know why I still get linker error. 0 Message Author Comment by:JennYeh2005-05-20 yes I do have winscard.lib inside folder C:\Program Files\BORLAND\CBuilder6\Lib\Psdk 0 LVL 2 Overall: Level C++ Copy // LNK2019e.cpp // compile by using: cl /EHsc LNK2019e.cpp // LNK2019 expected #include using namespace std; template class Test { // The operator<< declaration does not match

You then compile B, which will succeed and generate B.lib. The error message shows you both the external symbol and its decorated name to help you find the cause of the error. In any case, the solution I need may help you out. an automated makefile) have been successfully removed.

How to handle a senior developer diva who seems unaware that his skills are obsolete? When browsing through the affect function in the code, there will be a reference to TCHAR or std::basic_string etc. But I don't think this is the only way to solve the problem. So I posted my answer here instead. –Malvineous Jan 17 '15 at 14:00 That question already has an accepted answer.

For member functions or static data members, the implementation must include the class scope selector. The object files XYGraph.obj and XYPlot.obj are put in a library project, CPPf90.lib. The linker is responsible for resolving all external symbol references in each object file when they are linked into an application or DLL.
