Ubuntu22系统，参考nginx文档Support for QUIC and HTTP/3 执行如下命令：

./configure     --with-debug     --with-http_v3_module     --with-cc-opt="-I../boringssl/include"     --with-ld-opt="-L../boringssl/build/ssl                    -L../boringssl/build/crypto"

时报错如下：

./configure: error: SSL modules require the OpenSSL library. You can either do not enable the modules, or install the OpenSSL library into the system, or build the OpenSSL library statically from the source with nginx by using --with-openssl= option.

但其实系统是有openssl库的：

➜  out git:(v1.1.0) ✗ openssl version
OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022)

必应了一下，参考了这两个：https://forum.nginx.org/read.php?2,299223  #2605 (NGINX + BoringSSL build error (NGINX 1.25.4 required Openssl)) – nginx

编译nginx时指定为c++ linker即可，具体步骤如下：

git clone --recurse-submodules -j8 https://github.com/google/ngx_brotli cd ngx_brotli/deps/brotli mkdir out && cd out cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DCMAKE_C_FLAGS="-Ofast -m64 -march=native -mtune=native -flto -funroll-loops -ffunction-sections -fdata-sections -Wl,--gc-sections" -DCMAKE_CXX_FLAGS="-Ofast -m64 -march=native -mtune=native -flto -funroll-loops -ffunction-sections -fdata-sections -Wl,--gc-sections" -DCMAKE_INSTALL_PREFIX=./installed .. cmake --build . --config Release --target brotlienc cd ../../../..  hg clone https://hg.nginx.org/nginx cd nginx ./auto/configure --user=www --group=www --prefix=/www/server/nginx --with-pcre --add-module=../ngx_brotli --with-http_v2_module --with-stream --with-stream_ssl_module --with-http_ssl_module --with-http_gzip_static_module --with-http_gunzip_module --with-http_sub_module --with-http_flv_module --with-http_addition_module --with-http_realip_module --with-http_mp4_module --with-ld-opt='-Wl,-E' --with-cc-opt=-Wno-error --with-ld-opt='-ljemalloc' --with-http_dav_module --with-http_v3_module --with-cc=c++ --with-cc-opt='-I ../boringssl/include -x c' --with-ld-opt='-L../boringssl/build/ssl -L../boringssl/build/crypto' make  sudo make install cd /usr/sbin sudo ln -s /www/server/nginx/sbin/nginx nginx -version # nginx version: nginx/1.25.5
