GLFW + Vulkan on OSX

GLFW + Vulkan on OSX

本文关键字：OSX on Vulkan GLFW      更新时间：2023-10-16

我正在为我的项目设置GLFW和Vulkan。对于Vulkan来说，我正在使用Moltenvk将Vulkan Compat和Glfw用于窗口创建。我使用的IS是使用Cmake系统的Clion。

从某些github问题来看，似乎对此设置有支持，但是那里没有人提到它是如何完成的。

）。

在这一点上，Clion可以看到GLFW和Vulkan标题，但我仍然需要正确链接它们。

完整的cmakelists.txt文件现在是：

cmake_minimum_required(VERSION 3.8)
project(VulkanEngine)
#set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} “${CMAKE_SOURCE_DIR}/cmake/Modules”)
set(CMAKE_CXX_STANDARD 17)
set(SOURCE_FILES src/main.cpp)
add_executable(VulkanEngine ${SOURCE_FILES})
#Finding and linking GLFW3
find_package(glfw3 3.2 REQUIRED)
if (glfw3_FOUND)
    include_directories(${glfw3_INCLUDE_DIRS})
    target_link_libraries (VulkanEngine ${glfw3_LIBRARIES})
endif (glfw3_FOUND)
#Finding and linking Vulkan
find_package (Vulkan)
if (Vulkan_FOUND)
    include_directories(${Vulkan_INCLUDE_DIRS})
    target_link_libraries (VulkanEngine ${Vulkan_LIBRARIES})
endif (Vulkan_FOUND)

Console在重新加载CMAKE项目时告诉以下内容：

-- Could NOT find Vulkan (missing:  Vulkan_LIBRARY) 
-- Configuring done
-- Generating done
-- Build files have been written to: /Users/mtesseract/dev/cpp/VulkanEngine/cmake-build-debug

对我来说，这表明GLFW已被发现和链接，但是当我尝试为GLFW构建" Hello World"时，我会收到以下消息：

Undefined symbols for architecture x86_64:
  "_glfwInit", referenced from:
      _main in main.cpp.o

我从glfw github页面https://git.io/v5ggn获得了findvulkan.cmake，因为它具有对熔融的支持，但是我不确定它是否会被cmake拾取。（我将文件放入（ProjectRoot）/cmake/模块/）

在这一点上，我没有关于为什么事情不正确的想法，因此请求帮助。

我找到了一个解决方案，至少在某种程度上似乎有效。在这一点上，我还有另一个问题要解决（GLFW似乎并没有涉及熔融的存在）。

到目前为止，该过程如下（可以在我的GitHub页面（github.com/mtesseracttech/vulkanengine）上找到：

Vulkan + GLFW + GLM Setup Process with CMake and Package Managers
Windows:
Preparation:
Create CLion Application Project 
Install MSYS2 (Cygwin-like package manager that includes a windows port of Arch's PacMan)
Install LunarG VK SDK
Download FindVulkan.cmake from GFLW's Github (it includes a path for MoltenVK(for OSX Later)) and put it in (proj_root/cmake/modules)
MSYS2 Commands:
$ pacman -Su //Updates pacman
$ pacman -Ss {packageName} //Is used for searching for exact package names
Installed Packages through msys2:
$ pacman -S mingw-w64-x86_64-toolchain //Installs the CLion toolchain that includes CMake, Make, GCC, etc.
$ pacman -S mingw-w64-x86_64-glfw //Installs GLFW
$ pacman -S mingw-w64-x86_64-glm //Installs GLM
$ pacman -S mingw-w64-x86_64-vulkan //Vulkan can also be installed through this method, but I went with LunarG
Enter the following in the CMakeLists.txt file in the root of the project:
######################################################################################
cmake_minimum_required(VERSION 3.8)
project(VulkanEngine)
set(CMAKE_CXX_STANDARD 17)
set(SOURCE_FILES src/main.cpp)
add_executable(VulkanEngine ${SOURCE_FILES})
#Setting up PkgConfig
find_package(PkgConfig REQUIRED)
#Finding and linking GLFW3
pkg_search_module(GLFW3 3.2 REQUIRED glfw3)
if(GLFW3_FOUND)
    message(STATUS "Found GLFW, Including and Linking now")
    include_directories(${GLFW3_INCLUDE_DIRS})
    target_link_libraries(VulkanEngine ${GLFW3_STATIC_LIBRARIES})
endif(GLFW3_FOUND)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/modules/")
#Finding and linking Vulkan
find_package (Vulkan)
if (VULKAN_FOUND)
    message(STATUS "Found Vulkan, Including and Linking now")
    include_directories(${VULKAN_INCLUDE_DIR})
    target_link_libraries (VulkanEngine ${VULKAN_LIBRARY})
endif (VULKAN_FOUND)

OSX:
Preparation
Create CLion Application Project 
Install HomeBrew (package manager)
Download MoltenVK
Download FindVulkan.cmake from GFLW's Github (it includes a path for MoltenVK(for OSX Later)) and put it in (proj_root/cmake/modules)
Homebrew:
brew update //Updates homebrew
brew install glfw //Installs GLFW
brew install glm //Installs GLM
MoltenVK:
Place MoltenVK/macOS's contents into /usr/local/lib
Place MoltenVK/macOS/MoltenVK.framework/headers's contents into /usr/local/inc/MoltenVK
CMake: 
Same as on windows, but in the FindVulkan.cmake file, add at the very end of the elseif(APPLE) block the line:
set(VULKAN_INCLUDE_DIR "/usr/local/include/MoltenVK")
This is not a pretty or flexible solution, but for now it will do.

我很确定这个解决方案不是理想的选择，因为Glfw没有使用这种策略在熔融上捡起，但至少是要编译的，所以我认为这是进步的。

似乎您的问题是您尚未定义VULKAN_SDK变量。确保将其指向/lib＆amp;的父文件夹。/在SDK中包括在SDK中，FindVulkan应该工作

VULKAN_SDK=/opt/vulkan/x86_64 cmake.
