跟着cherno手搓游戏引擎【11】静态库、警告消除(渲染预热）
premake修改：
SRC下的premake
workspace "YOTOEngine" -- sln文件名
architecture "x64"
configurations{
"Debug",
"Release",
"Dist"
}
startproject "Sandbox"
-- https://github.com/premake/premake-core/wiki/Tokens#value-tokens
-- 组成输出目录:Debug-windows-x86_64
outputdir = "%{cfg.buildcfg}-%{cfg.system}-%{cfg.architecture}"
-- 包含相对解决方案的目录
IncludeDir={}
IncludeDir["GLFW"]="YOTOEngine/vendor/GLFW/include"
IncludeDir["Glad"]="YOTOEngine/vendor/Glad/include"
IncludeDir["ImGui"] ="YOTOEngine/vendor/imgui"
IncludeDir["glm"] ="YOTOEngine/vendor/glm"
--项目中包含某包
include "YOTOEngine/vendor/GLFW"
include "YOTOEngine/vendor/Glad"
include "YOTOEngine/vendor/imgui"
project "YOTOEngine" --YOTOEngine项目
location "YOTOEngine"--在sln所属文件夹下的YOTOEngine文件夹
kind "StaticLib"--修改为lib静态库
language "C++"
targetdir ("bin/" .. outputdir .. "/%{prj.name}") -- 输出目录
objdir ("bin-int/" .. outputdir .. "/%{prj.name}")-- 中间目录
cppdialect "C++17"
staticruntime "on"--打开
pchheader "ytpch.h"
pchsource "YOTOEngine/src/ytpch.cpp"
-- 包含的所有h和cpp文件
files{
"%{prj.name}/src/**.h",
"%{prj.name}/src/**.cpp",
"%{prj.name}/vendor/glm/glm/**.hpp",
"%{prj.name}/vendor/glm/glm/**.inl"
}
defines{
"_CRT_SECURE_NO_WARNINGS"
}
-- 包含目录
includedirs{
"%{prj.name}/src",
"%{prj.name}/vendor/spdlog-1.x/include",
"%{IncludeDir.GLFW}",
"%{IncludeDir.Glad}",
"%{IncludeDir.ImGui}",
"%{IncludeDir.glm}"
}
links{
"GLFW",-- GLFW.lib库链接到YOTOEngine项目中
"Glad",-- Glad.lib库链接到YOTOEngine项目中
"ImGui",-- ImGui.lib库链接到YOTOEngine项目中
"opengl32.lib"
}
-- 如果是window系统
filter "system:windows"
-- On:代码生成的运行库选项是MTD,静态链接MSVCRT.lib库;
-- Off:代码生成的运行库选项是MDD,动态链接MSVCRT.dll库;打包后的exe放到另一台电脑上若无这个dll会报错
systemversion "latest" -- windowSDK版本
-- 预处理器定义
defines{
"YT_PLATFORM_WINDOWS",
"YT_BUILD_DLL",
-- "YT_ENABLE_ASSERTS",
"GLFW_INCLUDE_NONE",-- 让GLFW不包含OpenGL
}
-- 编译好后移动Hazel.dll文件到Sandbox文件夹下
-- postbuildcommands{
-- ("{COPY} %{cfg.buildtarget.relpath} ../bin/" .. outputdir .. "/Sandbox")
-- }
-- 不同配置下的预定义不同

之后点击重构
修改宏定义，把动态库的定义删除

#define BIT(x)(1<imGui.Layer.cpp:强转float，把警告消除，实在找不到不改也没关系
io.DisplaySize = ImVec2((float)app.GetWindow().GetWidth(), (float)app.GetWindow().GetHeight());先水一期，下一期开启渲染！
