I had a similar problem today, and I solved it referring to Visual Studio can’t build due to rc.exe. To fix the issue, do next steps: Add this to your PATH environment variables: C:\Program Files (x86)\Windows Kits\10\bin\x64 Copy these files rc.exe & rcdll.dll from C:\Program Files (x86)\Windows Kits\8.1\bin\x86 to C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin … Read more
There exists a syntax to get the address of the member function in MSVC (starting from MSVC 2005 IMHO). But it’s pretty tricky. Moreover, the obtained pointer is impossible to cast to other pointer type by conventional means. Though there exists a way to do this nevertheless. Here’s the example: // class declaration class MyClass … Read more
stdafx.h is a file, generated by Microsoft Visual Studio IDE wizards, that describes both standard system and project specific include files that are used frequently but hardly ever change. Compatible compilers (for example, Visual C++ 6.0 and newer) will pre-compile this file to reduce overall compile times. Visual C++ will not compile anything before the … Read more
I’ll just copy an example from my “notebook” int foo(void*); template<typename T> struct S { S() { int i = foo(0); } // A standard-compliant compiler is supposed to // resolve the ‘foo(0)’ call here (i.e. early) and // bind it to ‘foo(void*)’ }; void foo(int); int main() { S<int> s; // VS2005 will resolve … Read more
You do not need to explicitly declare the destructor in a derived class: § 15.4 Destructors [class.dtor] (emphasis mine) A destructor can be declared virtual (13.3) or pure virtual (13.4); if any objects of that class or any derived class are created in the program, the destructor shall be defined. If a class has a … Read more
This problem doesn’t come up very often. The solution I’m familiar with was designed by Doug McIlroy and appears in Bjarne Stroustrup’s books (presented in both Design & Evolution of C++ section 12.8 and The C++ Programming Language section 25.6). According to the discussion in Design & Evolution, there was a proposal to handle this … Read more
Have you included all of the following headers? <fstream> <istream> <iostream> <string> My guess is you forgot <string>. On a side note: That should be std::cout and std::endl.
I had the same error message, but none of the answers here solved it for me. So if you Encounter that Problem when creating a DLL Project that uses MFC, it can be resolved by entering the following line: extern “C” { int __afxForceUSRDLL; } to the cpp file where DllMain is defined. Then your … Read more
Look at the error message from gcc: a.cpp:16: error: call of overloaded ‘function(double, double)’ is ambiguous a.cpp:3: note: candidates are: void function(int, int) a.cpp:9: note: void function(float, float) A call to either function would require truncation, which is why neither is preferred over the other. I suspect you really want void function(double y,double w). Remember … Read more
You can’t do this. They have exported C++ classes from their dll, rather than C-functions. The difference is, c++ functions are always exported with names in a mangled form that is specific to a particular version of the compiler. Their dll is usable by msvc only in that form, and will probably not even work … Read more
