使用 CPack 创建 Brew 包

Question

一直在寻找这个，但找不到示例或好的文档。有没有人有如何使用 cmake 中的 cpack 创建 brew 包的示例？

Answer 1

浏览homebrew-core存储库，基本上没有一个包直接使用 CPack。卤化物的公式非常简单且富有启发性。

class Halide < Formula

  livecheck do
    url :stable
    strategy :github_latest
  end

  bottle do
    sha256 cellar: :any,                 arm64_monterey: "7f338eeb5f667a39bf8c7b9e31975ead7efd0b93a521376f9a8b8ea01f15a2e8"

    sha256 cellar: :any,                 big_sur:        "ecafe1ae5a96849e3f62a7085b1a99a6dd1ed5a5ee33413a543373ff9004741f"

  end

  depends_on "cmake" => :build
  depends_on "jpeg"
  depends_on "libpng"
  depends_on "llvm"
  depends_on "python@3.10"

  fails_with gcc: "5" # LLVM is built with Homebrew GCC

  def install
    mkdir "build" do
      system "cmake", "..", *std_cmake_args, "-DHalide_SHARED_LLVM=ON"
      system "make"
      system "make", "install"
    end
  end

  test do
    cp share/"doc/Halide/tutorial/lesson_01_basics.cpp", testpath
    system ENV.cxx, "-std=c++17", "lesson_01_basics.cpp", "-L#{lib}", "-lHalide", "-o", "test"
    assert_match "Success!", shell_output("./test")
  end
end

然而，这一行很重要：

system "cmake", "..", *std_cmake_args, "-DHalide_SHARED_LLVM=ON"

将会成功。该std_cmake_args变量由以下设置组成：

      -DCMAKE_INSTALL_PREFIX=#{install_prefix}
      -DCMAKE_INSTALL_LIBDIR=#{install_libdir}
      -DCMAKE_BUILD_TYPE=Release
      -DCMAKE_FIND_FRAMEWORK=#{find_framework}
      -DCMAKE_VERBOSE_MAKEFILE=ON
      -Wno-dev
      -DBUILD_TESTING=OFF

您的项目根本不覆盖这些内容，这一点非常重要。
