If you're in a situation where you think the directory should be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl

安装openssl并指定了OPENSSL_DIR=C:\OpenSSL-Win64后openssl的问题解决，但是libsodium-ffi编译不过。
问题是：

貌似是卡在Powershell版本不对，我用的是msys2，切换到win7的ps上依然提示这个错误。

[e2ge]

手动下载libsodium-1.06-msvc
编译：
OPENSSL_DIR=C:\OpenSSL-Win64 OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes SODIUM_LIB_DIR=C:\libsodium-1.0.16-msvc\x64\Release\v141\static cargo build --release

libsodium-ffi可以编译通过，但是最后link出现错误：
= note: LINK : fatal error LNK1181: cannot open input file 'sodium.lib'

用
SODIUM_LIB_DIR=C:\libsodium-1.0.16-msvc\x64\Release\v141\static cargo build --release
单独编译libsodium-ffi发现release文件夹下面出现liblibsodium.d和liblibsodium.rlib
多了一个lib，不知道是不是这个问题。

[zonyitoo]

是这个问题，文件名没有按Windows的来。
但是AppVeyor上编译过了哦，你看看这个跟你的编译方法有什么不同？
https://github.com/shadowsocks/shadowsocks-rust/blob/master/appveyor.yml

[e2ge]

看了你的appveyor，没感觉有什么不同。
不指定SODIUM_LIB_DIR，就提示ps版本不对，需要大于4.0
指定SODIUM_LIB_DIR，最后link错误
可能是win7的原因？appveyor可能win版本更高一些吧。

[e2ge]

在win7上安装ps5.1就可以了，看来指定SODIUM_LIB_DIR不work。
ps5.1下载地址：https://www.microsoft.com/en-us/download/details.aspx?id=54616
msys2编译命令：
OPENSSL_DIR=C:\\OpenSSL-Win64 OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes cargo build --release

[e2ge]

在mingw64下也可以编译通过
toolchain：stable-x86_64-pc-windows-gnu
安装mingw-w64-x86_64-openssl，mingw-w64-x86_64-gcc，mingw-w64-x86_64-pkg-config
然后SODIUM_BUILD_STATIC=yes cargo build --release
开始的时候用的msys2的gcc，版本太低，总是出现gcc错误，后来发现pkg-config也必须用mingw64版，不然会报找不到lssl，lz和lcrypt

[zonyitoo]

确实比较复杂了……我手边没有Windows机器无法Debug...

[zonyitoo]

如果有能总结出来的经验能整理一下吗？我更新到Readme里

[e2ge]

我稍微总结一下吧，因为我用的是win7，可能在win10系统中不会出现类似的问题。

msvc abi编译环境：vs 2015+powershell 5.1+openssl 1.1.0h
shell用msys2或cmd都可以，只需要注意%HOMEPATH%\.cargo\bin在环境变量里就可以。
ps5.1下载地址：https://www.microsoft.com/en-us/download/details.aspx?id=54616
msys2编译命令：
OPENSSL_DIR=C:\\OpenSSL-Win64 OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes cargo build --release
OPENSSL_LIB_DIR=C:\\OpenSSL-Win64\lib\\VC\\static OPENSSL_LIBS=libcrypto64MT:libssl64MT OPENSSL_INCLUDE_DIR=C:\\OpenSSL-Win64\\include OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes cargo build --release
(cmd需要使用set）
遇到的错误和解决办法：

1. 缺少OpenSSL（安装openssl并指定OPENSSL_DIR=C:\OpenSSL-Win64）
2. 缺少libsodium（增加SODIUM_BUILD_STATIC=yes）
3. libsodium-ffi编译失败，powershell版本太低（安装powershell 5.1）
4. 手动下载libsodium并指定SODIUM_LIB_DIR=C:\libsodium-1.0.16-msvc\x64\Release\v141\static 最后会出现link错误，安装powershell 5.1后可不用指定SODIUM_LIB_DIR

gnu abi编译环境：msys2+mingw-w64-x86_64-gcc+mingw-w64-x86_64-pkg-config
openssl可以使用mingw64的，也可以用手动安装的。
mingw64版本openssl：pacman -S mingw-w64-x86_64-openssl
虽然也有mingw64的libsodium，但是不用SODIUM_BUILD_STATIC=yes仍然会报错，可能是版本太低？版本号1.0.12（重试了一遍，可以编译过，之前的错误可能是msys pkg-config的问题）
shell用mingw64，添加%HOMEPATH%\.cargo\bin到环境变量
使用mingw64的openssl库编译：
SODIUM_BUILD_STATIC=yes cargo build --release
或者
pacman -S mingw-w64-x86_64-libsodium
SODIUM_STATIC=yes cargo build --release
但是静态化openssl编译不过（OPENSSL_STATIC=yes）
rust-lang/rust#47048
https://stackoverflow.com/questions/48454201/statically-linking-curl-using-openssl-in-windows
使用手动安装openssl编译命令（可静态化openssl）：
OPENSSL_DIR=C:\\OpenSSL-Win64 OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes cargo build --release
遇到的错误和解决办法：

1. gcc报错（默认pacman -S gcc安装的是msys版本的gcc，版本太低，需要pacman -S mingw-w64-x86_64-gcc，pkg-config同理）
2. 缺少lssl，lz和lcrypt（需要使用mingw-w64-x86_64-pkg-config，不是pkg-config）

冏，最后发现其实是我的msys2没有升级到最新的版本，msys2的gcc和pkg-config版本都太低了。
需要反复pacman -Syu，不过msys repo里面没有libsodium

[DeepAQ]

It seems that OpenSSL cannot be statically linked even if OPENSSL_STATIC=yes is set.
I am building under Windows Server 2016 and msvc toolchains.
Does anyone have any idea?

[e2ge]

@DeepAQ
Because MSVC uses a different C++, you should specify the openssl dll of msvc version.

You should download openssl and install in a location such as C:\\OpenSSL-Win64 and compile with openssl statically like this:

OPENSSL_LIB_DIR=C:\\OpenSSL-Win64\lib\\VC\\static OPENSSL_LIBS=libcrypto64MT:libssl64MT OPENSSL_INCLUDE_DIR=C:\\OpenSSL-Win64\\include OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes cargo build --release

It works. Thanks!

[bigtan]

改天写个帖子，windows上面用vcpkg辅助编译非常的方便。

[testcaoy7]

@bigtan 能大致说一下Windows下的编译过程吗？

用MSVC编译不了，找不到llvm-config和clang lib。

error: failed to run custom build command for libsodium-ffi v0.2.2

cargo:warning=couldn't execute llvm-config --prefix (error: 系统找不到指定的文件。 (os error 2))
cargo:warning=set the LLVM_CONFIG_PATH environment variable to a valid llvm-config executable

[zonyitoo]

这个找不到llvm-config的warning可以忽略，没有也可以跑

cargo:warning=couldn't execute llvm-config --prefix (error: 系统找不到指定的文件。 (os error 2))
cargo:warning=set the LLVM_CONFIG_PATH environment variable to a valid llvm-config executable

要装一个libclang

1. 下一个llvm装上：http://releases.llvm.org/9.0.0/LLVM-9.0.0-win64.exe ，然后配置一下PATH，或者让LIBCLANG_PATH指向安装的地址

2. 如果你使用的method并不需要用到libsodium，可以直接把它关掉

   cargo build --no-default-feature --features "trust-dns aes-cfb"
   

   具体的feature可以自由指定，只要不填sodium就可以。

考虑直接用Docker编一个：https://github.com/shadowsocks/shadowsocks-rust/blob/master/build/Dockerfile.x86_64-pc-windows-gnu ，我用笔记本编译的时候应该是爆内存了没编出来，今晚有空我编一个出来放在Release里

[z16166]

用cargo build --no-default-features --features "trust-dns aes-cfb"编过去了。
能否在主页的README.md中加入windows编译步骤。

昨天折腾这个sodium搞了几个小时，连clang/llvm都从源码编译了一遍也没搞定。

[zonyitoo]

不同的Windows方法都不太一样，还可以用vcpkg或者apt-get的方式来装依赖

[z16166]

"官方"可以给出一个标准windows环境下的编译步骤，比如win10 x64 + MSVC 2019 + vcpkg这种具体的环境。

至于其它环境下，让编译者自己搞定。

[e2ge]

我试了一下，gnu和msvc都是可以编译的。
安装LLVM：http://releases.llvm.org/9.0.0/LLVM-9.0.0-win64.exe
会自动提示设置Path
安装openssl：https://slproweb.com/products/Win32OpenSSL.html

gnu的话用mingw：
OPENSSL_DIR=C:\\OpenSSL-Win64 OPENSSL_STATIC=yes SODIUM_BUILD_STATIC=yes cargo build --release

msvc用cmd:
创建一个简单的bat文件：

set "OPENSSL_LIB_DIR=C:\OpenSSL-Win64\lib\VC\static"
set "OPENSSL_LIBS=libcrypto64MT:libssl64MT"
set "OPENSSL_INCLUDE_DIR=C:\OpenSSL-Win64\include"
set "OPENSSL_STATIC=yes"
set "SODIUM_BUILD_STATIC=yes"
cargo build --release
pause

保存到shadowsocks-rust文件夹，双击就开始编译了。

[e2ge]

libsodium-ffi改成了libsodium-sys，那"SODIUM_BUILD_STATIC=yes"应该没什么用了吧？

[zonyitoo]

是的，默认会自己去尝试Build

[bigtan]

#163
直接用这个，编译非常顺畅

[zonyitoo]

https://github.com/shadowsocks/shadowsocks-rust/blob/master/build/Dockerfile.x86_64-pc-windows-gnu

或者看一下Docker Build的写法。

[e2ge]

@bigtan vcpkg是比较方便。最新1.8.0版本sodium改成libsodium-sys，这样的vcpkg应该就没有必要再安装静态libsodium了吧？

@zonyitoo Dockerfile使用的还是gnu abi，其实我也不清楚msvc和gnu性能上有没有差别，文件size上倒是没什么差别。说不定有人就是想用msvc呢😂

[zonyitoo]

因为没有办法用 Docker 编出来 msvc ABI 的 Binary。

应该差别不大，差别比较大的是 cygwin 。

[voltwu]

我的可以正常编译了，通过cargo可以编译，但是在Shadowsocks-android目录下，通过 gradle就编译不了。

[zonyitoo]

Please @Mygod @madeye check this problem.

[LuoZijun]

@zonyitoo PR #319 应该可以避免发生这个问题。

[hw1020]

我的可以正常编译了，通过cargo可以编译，但是在Shadowsocks-android目录下，通过 gradle就编译不了。

我也是

[zonyitoo]

I think it is because shadowsocks-android uses stable Rust by default.
