My trick for common GL error handling

// Thanassis Tsiodras, Dr.-Ing
// My C++11 trick for common GLerror handling (regardless of whether the API returns something or not)
// March 13, 2012

// User code:
   ...
   // this API (glCreateShader) returns something
   shader_ = GLERROR(glCreateShader(VertexShader==shaderType?GL_VERTEX_SHADER:GL_FRAGMENT_SHADER));
   // this (glShaderSource) doesn't
   GLERROR(glShaderSource(shader_, 1, &pShaderCode, NULL));
   // neither does this (glCompileShader)
   GLERROR(glCompileShader(shader_));
   ...

// Library code: how I did it with lambdas and std::function

void commonCode(const char *file, size_t lineno) {
    GLenum err = glGetError();
    if (err != GL_NO_ERROR) {
        while (err != GL_NO_ERROR) {
            std::cerr <<
                "glError: " << (char *)gluErrorString(err) <<
                " (" << file << ":" << lineno << ")" << std::endl;
            err = glGetError();
        }
        throw "Failure in GLSL...";
    }
}

template <class T>
auto glError(std::function<T()>&& t, const char *file, size_t lineno) -> decltype(t()) {
    auto ret = t();
    commonCode(file,lineno);
    return ret;
}

template<>
void glError(std::function<void(void)>&& t, const char *file, size_t lineno) {
    t();
    commonCode(file,lineno);
}

template <class T>
auto helper (T&& t) -> std::function<decltype(t())()>
{
    std::function<decltype(t())()> tmp = t;
    return tmp;
}

#define GLERROR( expr ) \
    [&]() { \
        return glError( helper( [&]() { return expr; } ),  __FILE__, __LINE__); \
    }()
