前言：

1，公司要給一線搞一個升級程序，需要在win下跑。 之前都是找開發總監幫忙，但是他最近比較忙。就讓我自己搞。有了下文.。說來慚愧，之前寫過一篇ubuntu下編譯windows的文章。里面的demo就一句話 fuck world。依賴的庫很少。這個是公司的工程，依賴的庫很多。想的有點簡單了。大家還是要把底子打好

工程介紹。

需要編譯patch.rs這個文件。

1，安裝target

rustup target add x86_64-pc-windows-gnu

2，安裝gcc?

 ?sudo apt-get install mingw-w64

執行編譯后提示?

?第一個坑：

因為沒有配置變量。簡單的說就是用了linux下的gcc ，肯定會失敗的。沒有找到對應的文件。

本質是 build-script 里調用的 C/匯編工具鏈仍然是 Linux 的 /usr/bin/gcc / /usr/bin/as，而不是 MinGW-w64 的交叉編譯器。于是：

rust 的配置文件中。增加env選項。

3,修改配置

.cargo/config.toml

[target.x86_64-pc-windows-gnu]
linker = "x86_64-w64-mingw32-gcc"
ar     = "x86_64-w64-mingw32-ar"rustflags = ["-L/usr/x86_64-w64-mingw32/lib","-luser32","-lgdi32","-lkernel32","-ladvapi32",
][env]
CC_x86_64_pc_windows_gnu  = "x86_64-w64-mingw32-gcc"
CXX_x86_64_pc_windows_gnu = "x86_64-w64-mingw32-g++"
AR_x86_64_pc_windows_gnu  = "x86_64-w64-mingw32-ar"
RANLIB_x86_64_pc_windows_gnu = "x86_64-w64-mingw32-ranlib"
CFLAGS_x86_64_pc_windows_gnu = "-DWINVER=0x0600 -D_WIN32_WINNT=0x0600"
CXXFLAGS_x86_64_pc_windows_gnu = "-DWINVER=0x0600 -D_WIN32_WINNT=0x0600"

4、在執行

 note: /usr/bin/x86_64-w64-mingw32-ld: cannot find -lUser32: No such file or directorycollect2: error: ld returned 1 exit status

ls /usr/x86_64-w64-mingw32/lib/libuser32.a? 查看了下有文件。那就是沒有建立鏈接。需要執行link命令

sudo ln -s /usr/x86_64-w64-mingw32/lib/libuser32.a \/usr/x86_64-w64-mingw32/lib/libUser32.a

原因：

• 在 x86_64-pc-windows-gnu 目標下，Rust 會讓 MinGW-w64 鏈接器把 Windows 系統庫 User32、Kernel32、Gdi32 … 加到命令行（見源碼里 -luser32 -lkernel32 等）?GitHub。

• 這些庫不是 DLL，而是 導入庫（libuser32.a、libkernel32.a …）。它們隨 MinGW-w64 CRT/headers 包一起提供。

• 你的 Linux 系統上只裝了 x86_64-w64-mingw32-gcc，卻 沒有裝對應的 CRT 和 Win32 API 導入庫，結果鏈接階段就找不到 libuser32.a，于是報錯。

吐槽：不是哥們（linux大佬們），你們這樣搞 真的好嗎。。。

執行。成功。朋友們 ，歡呼吧 enjoy rust 。

但是體積非常大190M。原因：

默認的 cargo build 是 Debug 構建，再加上：

• Windows GNU 目標會把 libstd、OpenSSL、Paho-MQTT 等一大堆依賴全都 靜態地 鏈進去；

• Debug 模式保留完整符號表，方便 gdb/VS Code 調試；

• 沒有做 LTO／代碼裁剪；

所以可執行文件非常大（上百 MB 很正常）。

執行優化命令

cargo build -p ${crate}--example patch --release --target x86_64-pc-windows-gnu

• -p/--package test告訴 Cargo 只對 test這個包動手，避免工作區里其它 crate 被順帶編譯。

• --example patch?表示只編譯 examples/patch.rs 生成的可執行文件。

體積：27M

繼續優化

cargo build -p {$crate}--example patch --profile release-size  --target x86_64-pc-windows-gnu

體積:1.6M 。完美。

解析：release-size

cargo.toml中添加 ；減少其他的附帶項

[profile.release-size]
inherits = "release"
# https://www.aloxaf.com/2018/09/reduce_rust_size/
strip = true  # Automatically strip symbols from the binary.
opt-level = 'z'  # Optimize for size.
lto = true #
panic = 'abort'
codegen-units = 1

GAME OVER

之后我編譯了整個crate，提示上面的問題。

cargo tree -e features | grep -i packet

能快速定位是哪條依賴鏈、哪個 feature 打開的，方便你決定 “裝 SDK” 還是 “關 feature

-lPacket 指的是 WinPcap / Npcap SDK 里的 Packet.lib (或 libPacket.a)。
在 Windows 下，只要你鏈接了 librdkafka、pnet、winpcap 等底層網絡庫，build-rs 通常都會

沒有lib文件

1. 下載 Npcap SDK
   https://npcap.com/#download → Npcap SDK（ZIP）。

2. 拷貝頭文件與靜態庫（假設 SDK 解壓到 ~/npcap-sdk）：

   sudo cp -R ~/npcap-sdk/Include/*  /usr/x86_64-w64-mingw32/include/
   sudo cp ~/npcap-sdk/Lib/x64/Packet.lib  /usr/x86_64-w64-mingw32/lib/

在編譯。成功。結束
