How to compile glm for use? And bug feedback

[sdragonx]

Define GLM_EXTERNAL_TEMPLATE in the header file, and enter the code in a cpp file:

pch.h:

#define GLM_EXTERNAL_TEMPLATE
// #define GLM_SILENT_WARNINGS // ???

#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/quaternion.hpp>
#include <glm/gtc/type_ptr.hpp>

#include <glm/ext.hpp>
#include <glm/gtx/intersect.hpp>
#include <glm/gtx/io.hpp>
#include <glm/gtx/matrix_decompose.hpp>
#include <glm/gtx/normal.hpp>
#include <glm/gtx/quaternion.hpp>
#include <glm/gtx/rotate_vector.hpp>
#include <glm/gtx/vector_angle.hpp>

glm_imp.cpp:

#undef GLM_EXTERNAL_TEMPLATE

#include <glm/glm.hpp>
#include <glm/gtc/matrix_transform.hpp>
#include <glm/gtc/quaternion.hpp>
#include <glm/gtc/type_ptr.hpp>

#include <glm/ext.hpp>
#include <glm/gtx/intersect.hpp>
#include <glm/gtx/io.hpp>
#include <glm/gtx/matrix_decompose.hpp>
#include <glm/gtx/normal.hpp>
#include <glm/gtx/quaternion.hpp>
#include <glm/gtx/rotate_vector.hpp>
#include <glm/gtx/vector_angle.hpp>

compilation produces many errors.

x:\include\glm\ext\quaternion_geometric.inl:7: error: 'call' is not a member of 'glm::detail::compute_dot<glm::qua<float, (glm::qualifier)0>, float, false>'
   return detail::compute_dot<qua<T, Q>, T, detail::is_aligned<Q>::value>::call(x, y);
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~

And in the process of gcc compilation, there will be many warnings that lead to too much output:

x:\include\glm\detail\type_vec2.hpp:108: warning: inline function 'constexpr glm::vec<2, T, Q>::vec(T) [with T = float; glm::qualifier Q = (glm::qualifier)0]' used but never defined
   GLM_CTOR_DECL explicit vec(T scalar);
                          ^~~

glm\ext\quaternion_geometric.hpp:

// #ifndef GLM_EXTERNAL_TEMPLATE  // forgot
#include "quaternion_geometric.inl"
// #endif

But I tried to fix this problem, and there were more errors after recompiling: (7081 errors)

I compiled glm, and after joining the glm library (libglm.a), there are still many errors: (1862 errors)
