warp: LLVM+Clang等のパッケージング

okuokuokuoku

というわけで、とりあえずWindows版のClangをパッケージングする。これにフロントエンドのwrapperを被せてツールチェインということにする。

バイナリはLLVMが公式でビルドしている:

そのうち自前のビルドに置き換えたいけど。。

必要なファイルの抽出

Windowsで必要なのは bin ディレクトリだけなので、それだけパッケージすれば良い。

環境の検出

conan profile detect で環境を検出できる。

$ conan profile detect
detect_api: Found msvc 17

Detected profile:
[settings]
arch=x86_64
build_type=Release
compiler=msvc
compiler.cppstd=14
compiler.runtime=dynamic
compiler.version=194
os=Windows

WARN: This profile is a guess of your environment, please check it.
WARN: The output of this command is not guaranteed to be stable and can change i
n future Conan versions.
WARN: Use your own profile files for stability.
Saving detected profile to e:\conan_home\profiles\default

(Conan2は基本的に環境を常に破壊するコンセプトになっているため、 conan profile detect は検出したプロファイルを自動的に保存する。)

ここで必要なのは arch=x86_64 と os=Windows で、これらを対象にしたprebuiltなバイナリパッケージを作成することになる。

ビルド

Conan2ではパッケージの作成は conan create コマンドで行う。適当にconanfile.pyを書いて、 conan create . すればパッケージが作成され、ローカルに自動的にインストールされる。

import os
from conan import ConanFile
from conan.tools.files import get, copy, download
from conan.errors import ConanInvalidConfiguration
from conan.tools.scm import Version


class WarpLlvmClangPackage(ConanFile):
    name = "llvmtoolchain-warp"
    version = "20.1.8.warp0"
    license = "DO_NOT_EXPORT"
    description = "(internal use only LLVM/Clang package)"
    settings = "os", "arch"
    package_type = "application"

    # FIXME: Download and extract on build phases
    extracted_path = "e:/clang+llvm-20.1.8-x86_64-pc-windows-msvc"

    def validate(self):
        if self.settings.arch != "x86_64" or self.settings.os != "Windows":
            raise ConanInvalidConfiguration("Only applicable for Windows/x86_64")

    def package(self):
        dirs_to_copy = ["bin"]
        for dir_name in dirs_to_copy:
            copy(self, pattern=f"{dir_name}/*", src=self.extracted_path, dst=self.package_folder, keep_path=True)

$ conan create .
