Netbeans C ++返回类型的模板化函数

Question

For some reason the code completion in netbeans can't figure out the return type of templated functions. Take the following example...

struct Test
{
   int val;
};

int main()
{
     vector<Test> v;
     Test t = {10};
     v.push_back(t);
     cout << v[0].val;  //Netbeans gives the warning "Unable to resolve identifier val"
     return 0;
}

The code compiles and runs fine but what is annoying is that I get this error all over my code when I use vectors. Also the code completion does not seem to work. When I type v[0]. there is no drop down giving me to option to choose val.

I am using netbeans 7.4 along with 64bit MinGW.

Answer 1

Well there seems to bug in the Netbeans 7.2 version and later it was fixed.

You can find the complete discussion and possible resolution on the same problem from the following link. Here you can find how to resolve this problem(possibly).

Netbeans 7.2 shows "Unable to resolve identifier" , although build is successful

Answer 2

按照以下链接执行一些简单的步骤来解析标识符， Netbeans 7.2显示“无法解析标识符”，尽管构建成功 1

Answer 3

try changing

struct Test
{
   int val;
};

with

typedef struct
{
    int val;
} Test;

in pure C "Test" would not be a defined type but "struct Test" would be. By changing to a typedef then you then have "Test" as a defined type.
