chromium编译避坑日记

编译环境

• 操作系统：Windows 10
• IDE：Visual Studio 2022 Community
• 编译器：LLVM 17.0.6
• chromiu版本：99.0.4844.94

坑

clang版本

• 错误

error: static_assert failed "Error in C++ Standard Library usage.
_EMIT_STL_ERROR(STL1000, "Unexpected compiler version, expected Clang 16.0.0 or newer.");
note: expanded from macro '_EMIT_STL_ERROR' static_assert(false, "Error in C++ Standard Library usage.")

• 原因：该版本的chromium代码自带的clang版本为14，编译环境要求clang 16+
• 方法：（有其他的方法还请告知）
  1. 安装LLVM 17.0.6
  2. 拷贝安装好的LLVM到${SRC}\third_party\llvm-build\LLVM
  3. 修改${SRC}\third_party\llvm-build\clang.gni文件

import("//build/toolchain/toolchain.gni")

# 修改为新的clang路径
default_clang_base_path = "//third_party/llvm-build/LLVM"

declare_args() {
  # Indicates if the build should use the Chrome-specific plugins for enforcing
  # coding guidelines, etc. Only used when compiling with Chrome's Clang, not
  # Chrome OS's.
  clang_use_chrome_plugins =
      is_clang && !is_nacl && current_os != "zos" &&
      default_toolchain != "//build/toolchain/cros:target"

  clang_base_path = default_clang_base_path
}

error: unable to find plugin 'find-bad-constructs'

• 原因：不支持自定义编译器
• 对策：修改args.gn

gn gen --ide=vs2022 --args="clang_use_chrome_plugins=false" out\Default
