如何解决错误LNK2019：未解决的外部符号_glfwinit
我有来自Vulkan教程的基本代码。我不是使用Visual Studio，而是选择仅从命令行中编译。 cl lib/*。lib main.cpp/i包括。我假设这些符号将在似乎正确编译的。
#define GLFW_INCLUDE_VULKAN
#include <GLFW/glfw3.h>
#define GLM_FORCE_RADIANS
#define GLM_FORCE_DEPTH_ZERO_TO_ONE
#include <glm/vec4.hpp>
#include <glm/mat4x4.hpp>
#include <iostream>
int main() {
glfwInit();
glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
GLFWwindow* window = glfwCreateWindow(800, 600, "Vulkan window", nullptr, nullptr);
uint32_t extensionCount = 0;
vkEnumerateInstanceExtensionProperties(nullptr, &extensionCount, nullptr);
std::cout << extensionCount << " extensions supported\n";
glm::mat4 matrix;
glm::vec4 vec;
auto test = matrix * vec;
while(!glfwWindowShouldClose(window)) {
glfwPollEvents();
}
glfwDestroyWindow(window);
glfwTerminate();
return 0;
}
这是编译器/链接器的完整输出

I have the basic code from the vulkan tutorial. I'm not using Visual Studio and opted to just compile from the command line. cl lib/*.lib main.cpp /I include. I sort of assumed that the symbols would be resolved in the .lib files which seem to compile properly, but it doesn't link so what do I do?
#define GLFW_INCLUDE_VULKAN
#include <GLFW/glfw3.h>
#define GLM_FORCE_RADIANS
#define GLM_FORCE_DEPTH_ZERO_TO_ONE
#include <glm/vec4.hpp>
#include <glm/mat4x4.hpp>
#include <iostream>
int main() {
glfwInit();
glfwWindowHint(GLFW_CLIENT_API, GLFW_NO_API);
GLFWwindow* window = glfwCreateWindow(800, 600, "Vulkan window", nullptr, nullptr);
uint32_t extensionCount = 0;
vkEnumerateInstanceExtensionProperties(nullptr, &extensionCount, nullptr);
std::cout << extensionCount << " extensions supported\n";
glm::mat4 matrix;
glm::vec4 vec;
auto test = matrix * vec;
while(!glfwWindowShouldClose(window)) {
glfwPollEvents();
}
glfwDestroyWindow(window);
glfwTerminate();
return 0;
}
This is the full output of the compiler/linker

首先，我必须安装Windows 10 SDK
然后，我不得不在通往VS2022的路径中更改我的vcvarsall
然后我必须运行
vcvarsall x64然后，我必须删除
glfw3.lib支持glfw3_mt.lib然后，我必须将
vulkan-1.lib添加到我的lib/目录最后，它编译并展示了一个窗户

Then I had to run the

glfw3.libin favor of theglfw3_mt.libThen I had to add the
