Question

I have been able to use OpenGL’s glVertexPointer function using the following C++ code:

glVertexPointer(3, GL_DOUBLE, 0, myMeasuredPoints.data());

myMeasuredPoints is a C++ vector with elements of type double. When compiling this code with Visual C++, there is no problem at all. However, when using MinGW to compile, I get the following error:

error: 'class std::vector<double, std::allocator<double>' has no member named 'data'

Strangely, I do not get this error any other place in the code where I invoke functions such as myMeasuredPoints.push_back() to push values onto the vector. These other instances have all been before using the .data() function, so it hasn’t simply been a case of the code crashing before reaching the other instances.

Any thoughts?

Answer 1

The data function was added in C++11. Make sure you compile with -std=c++0x or -std=c++11 and have a version of MinGW that includes the function.

If that’s not possible, you can use the usual C++03 variant:

&myMeasuredPoints[0]
