源码编译zig

添加llvm18的源

zig要求这个版本

# uos v20
deb http://apt.llvm.org/buster/ llvm-toolchain-buster main
deb-src http://apt.llvm.org/buster/ llvm-toolchain-buster main
# 18 
deb http://apt.llvm.org/buster/ llvm-toolchain-buster-18 main
deb-src http://apt.llvm.org/buster/ llvm-toolchain-buster-18 main
# 19

配置编译环境

sudo apt install -y build-essential cmake clang-18 libclang-18-dev libclang-cpp18-dev llvm-18 llvm-18-dev lld-18 liblld-18-dev libpolly-18-dev libllvm18

alias llvm-config=/lib/llvm-18/bin/llvm-config
llvm-config --cxxflags --ldflags --system-libs --libs core

下载zig源码编译

在build目录构建，方便删除

git clone https://mirror.ghproxy.com/https://github.com/ziglang/zig.git
cd zig
mkdir build
cd build
cmake ..  -DCMAKE_PREFIX_PATH=/usr/lib/llvm-18  -DZIG_STATIC_LLVM=ON
make

https://github.com/ziglang/zig/wiki/Building-Zig-From-Source

以上步骤为了验证是否能正常打包。

构建debian包

准备环境

sudo apt install dh-make

制作debian文件

生成debian目录

#移除编译build目录，否则--createorig参数创建源码包会包含这些
rm -rf build

#获取最新tag信息,用于作为debian版本
ver=$(git describe --tags --abbrev=0)
git checkout $ver
dh_make  -p zig_$ver  -s -y --createorig
rm -f debian/*.ex

编辑debian内的文件,关键是添加Build-Depends，方便apt build-dep .自动下载打包依赖。 如果有修改，需要dch -i命令添加changelog

debian/control文件内容。

dpkg-buildpackage打包

# 因为有Cmake文件，直接构建即可
rm -rf  .zig-cache/
dpkg-buildpackage -uc -us -tc 

可能会提示gpg签名失败，不要紧，已经打包好了。

dpkg -c ../zig_*.deb
