very simple code, and getting error C2712, could not understand why

c++, try-except, visual-studio

Solution

Here is the solution. For more details read Compiler Error C2712

#include <string>
struct myStruct
{
    static std::string foo() {return "abc";}
};

void koo()
{
    __try 
    { }
    __except (true)
    { }
}

int main ()
{
    myStruct::foo();   
    koo();
    return 0;
}

Extra Note: no need `static` if no declaration using your struct (myStruct).

Problem

I'm having trouble for a while with `error C2712: Cannot use __try in functions that require object unwinding`, after narrowing the problem, I was left with a very very simple code, and i can not understand why it causes this error. I am using Visual Studio under windows. I am compiling with /EHa (I do not use /EHsc) The reason I use `__try/__except` and not `try/catch` is because I want to catch ALL the errors, and do not want the program to crash under any circumstances, including for example division by 0, that try-catch does not catch. ``` #include <string> static struct myStruct { static std::string foo() {return "abc";} }; int main () { myStruct::foo(); __try { } __except (true) { } return 0; } ``` output: ``` error C2712: Cannot use __try in functions that require object unwinding ```
