quiche编译-编程知识

quiche编译

netty http3使用了rust语言的quiche，quiche使用了c++语言的boringssl，
网上没有找到编译好的quiche，只能自己搭建rust环境编译

1、rust安装

见官网https://www.rust-lang.org/tools/install
我是用的是windows的ubuntu，所以直接使用：

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

2、其他基础库

需要安装cmake、go、perl等，如果没有安装，编译过程也会提示

sudo apt install cmake
sudo apt install golang
sudo apt install perl

3、下载quiche代码和boringssl代码

将boringssl代码放到quiche/deps/boringssl/
https://github.com/cloudflare/quiche
https://github.com/google/boringssl.git

4、编译quiche

QUICHE_BSSL_PATH="/mnt/d/codeC/quiche-0.6.0/deps/boringssl" cargo build

这时会出现错误：

error: could not find native static library `crypto`, perhaps an -L flag is missing?
error: could not compile `quiche` (lib) due to previous error

修改quiche/src/build.rs：
println!(“cargo:rustc-link-search=native={}”, build_dir);
修改为：

println!("cargo:rustc-link-search=native={}/crypto", build_dir);
println!("cargo:rustc-link-search=native={}/ssl", build_dir);

在这里插入图片描述
5、编译boringssl

cd boringssl
mkdir build
cmake ..
make

这时有可能提示：

= note: /usr/bin/ld: /mnt/d/codeC/quiche-0.6.0/deps/boringssl/build//crypto/libcrypto.a(bcm.c.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC/usr/bin/ld: final link failed: bad valuecollect2: error: ld returned 1 exit status
