搭建bazel windows环境

一、依赖

  1. 安装msys2。由于构建bazel本身，以及大量bazel构建脚本包含genrule需要bash，因此目前windows环境下使用bazel，强依赖bash
    https://github.com/msys2/msys2-installer/releases/download/2024-11-16/msys2-x86_64-20241116.exe
  2. 安装vs studio
  3. 安装java。构建bazel本身以及bazel运行需要java
  4. 构建bazel. 
    export http_proxy="http://192.168.2.1:1081"
export https_proxy="http://192.168.2.1:1081"
export MSYS_NO_PATHCONV=1
export MSYS2_ARG_CONV_EXCL="*"
export BAZEL_VC="C:/Program Files/Microsoft Visual Studio/2022/Enterprise/VC"
export BAZEL_SH="$(cygpath -m $(realpath $(which bash)))"
export PATH="/c/Python311:/c/Program Files/bazel::$PATH"
export JAVA_HOME="C:/Program Files/Java/jdk-21"
env EXTRA_BAZEL_ARGS="--tool_java_runtime_version=local_jdk" ./compile.sh

二、配置

修改系统环境变量


BAZEL_SH=E:/msys64/usr/bin/bash.exe
JAVA_HOME=C:\Program Files\Java\jdk-21
CLASSPATH=.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;
Path=C:\Strawberry\perl\bin:C:\Python311\Scripts:C:\Python311:C:\Program Files\CMake\bin:C:\Program Files\bazel:C:\ProgramData\chocolatey\lib\gperf\tools:C:\Strawberry\perl\site\bin:C:\Strawberry\perl\bin:%JAVA_HOME%\bin

编译命令

$env:http_proxy = "http://192.168.2.1:1081"
$env:https_proxy = "http://192.168.2.1:1081"
$env:Path += ";C:/Python311;C:/ProgramData/chocolatey/bin"
$env:BAZEL_SH="E:/msys64/usr/bin/bash.exe"
$env:BAZEL_VC="C:/Program Files/Microsoft Visual Studio/2022/Enterprise/VC"
$env:PYTHON_LIB_PATH="C:/Python311/Lib"
$env:PYTHON_DIRECTORY="C:/Python311/Scripts"
$env:INCLUDE="C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.41.34120\include;C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.41.34120\atlmfc\include;C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary\VS\include;C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\ucrt;C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary\VS\UnitTest\include;C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\um;C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\shared;C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\winrt;C:\Program Files (x86)\Windows Kits\10\Include\10.0.22621.0\cppwinrt;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\Include\um"
$env:LIB += ";C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22621.0\ucrt\x64;C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary\VS\UnitTest\lib;C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22621.0\um\x64;C:\Program Files (x86)\Windows Kits\NETFXSDK\4.8\lib\um\x64"

bazel --output_user_root=D:\bazel_cache build //...

三、注意点

  1. 从github下载的bazel自带了jdk，bazel没法访问使用自签名证书网站，因此需要自己构建bazel，然后使用命令信任自签名证书

    keytool -importcert -keystore "C:\Program Files\Java\jdk-21\lib\security\cacerts" -file "D:\share\ubuntu\cert\certs\ca.root.cert.pem" -alias gitlab.ca -storepass changeit

  2. 对于国内网络环境，编译时，可以在powersell设置代理环境变量

    $env:http_proxy = "http://192.168.2.1:1081"
$env:https_proxy = "http://192.168.2.1:1081"

  3. windows对路径中单文件名长度有限制，基本所有人都会遇到这个问题，比如编译中遇到找不到某个文件，明明该文件就是存在的，即使修改系统配置打开Enable Win32 long paths，然后会有路径长度问题。需要指定bazel --output_user_root=D:\bazel_cache build //...，或者在.bazelrc中加入，需要注意的是--output_base选项是针对单个项目的，因此不同项目不可以使用同一个路径

    startup --windows_enable_symlinks
startup --output_base=D:/bazel_cache

    ERROR: C:/users/tiger/_bazel_tiger/rtzwbyqu/external/com_google_protobuf/src/google/protobuf/json/BUILD.bazel:66:11: Compiling src/google/protobuf/json/internal/zero_copy_buffered_stream.cc [for tool] failed: (Exit 2): cl.exe failed: error executing CppCompile command (from target @@com_google_protobuf//src/google/protobuf/json:zero_copy_buffered_stream) C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.41.34120\bin\HostX64\x64\cl.exe ...

pacman -Syu
pacman -S gperf

dumpbin /SYMBOLS bazel-out/x64_windows-opt/bin/external/curl/curl.lib | findstr "lzma_code"
dumpbin /DEPENDENTS bazel-bin/my_project/my_binary.exe
