VulkanSamples编译记录

按照BUILD.md说明，先安装依赖项

sudo apt-get install git build-essential libx11-xcb-dev \
    libxkbcommon-dev libwayland-dev libxrandr-dev

然后创建一个新文件夹build，在该目录下更新依赖项

cd VulkanSamples
mkdir build
cd build
python ../scripts/update_deps.py

会生成vulkan loader和头文件，以及一个cmake文件，接下来执行

cmake -C helper.cmake ..
或者
cmake -DCMAKE_BUILD_TYPE=Debug \
      -DVULKAN_HEADERS_INSTALL_DIR=“注意修改路径” \
      -DVULKAN_LOADER_INSTALL_DIR=“注意修改路径” \
      -DCMAKE_INSTALL_PREFIX=install ..

提示 spirv-tools 安装不成功，因为原来的下载链接失效了

 可以从GitHub上手动下载SPIRV-Tools/docs/downloads.md at main · KhronosGroup/SPIRV-Tools · GitHub

然后把文件解压，拷到VulkanSamples/spirv-tools 目录下，再重新执行上面命令。

再进入VulkanSamples根目录下，执行make 或者 cmake --build 命令。

提示错误 draw_textured_cube 是一个目录，不能生成可执行文件，是因为文件和目录有重名。

可以改一下CMakeLists文件，换个名字，然后在重新执行make
