编译

编译 mosquitto

安装依赖：

• gmake 编译工具
• cmake 编译工具
• libcjson 命令行支持json格式输出依赖
• libwebsockets websocket依赖

pkg install gmake libcjson

根据开发者描述:https://github.com/eclipse/mosquitto/issues/2060
libwebsockets 高于v2.4.2后会默认关闭LWS_WITH_EXTERNAL_POLL选项.导致mosquitto功能受损.

所以,要么选择低版本的libwebsockets,要么重新手动编译高版本.

这里选择重新手动编译高版本,开启LWS_WITH_EXTERNAL_POLL选项.

• cmake 编译:

git clone https://libwebsockets.org/repo/libwebsockets
cd libwebsockets
git checkout v4.1.6

在Unix上编译时,需将CMakefile.txt中的-Werror项,删去!!!!
否则编译不了

cd ..
mkdir build
cd build
cmake \
-DLWS_WITH_EXTERNAL_POLL=ON \
-DLWS_WITH_HTTP2=ON \
-DLWS_WITHOUT_TESTAPPS=ON \
-DLWS_UNIX_SOCK=ON \
-DLWS_IPV6=ON \
../libwebsockets
make
make install

• cmake on MocOS

  cmake \
  -DCMAKE_INSTALL_PREFIX=/usr/local/opt/libwebsockets \
  -DLWS_WITH_EXTERNAL_POLL=ON \
  -DLWS_WITH_HTTP2=ON \
  -DLWS_WITHOUT_TESTAPPS=ON \
  -DLWS_UNIX_SOCK=ON \
  -DLWS_IPV6=ON \
  -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl \
  ../libwebsockets

  编译

• gmake 编译:

配置config.mk

• WITH_WEBSOCKETS:=no -> yes
• WITH_CJSON:=yes

gmake CFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib"
gmake install

• cmake 编译:

mkdir build
cd build
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DOPENSSL_ROOT_DIR=/usr/local \
-DWITH_WEBSOCKETS=ON \
-DDOCUMENTATION=OFF \
-DCMAKE_C_FLAGS="-I/usr/local/include" \
-DCMAKE_EXE_LINKER_FLAGS="-L/usr/local/lib" \
../mosquitto
make
make install

• ‘cmake’ on MacOS

  cmake \
  -DCMAKE_INSTALL_PREFIX=/usr/local/opt/mosquitto \
  -DDOCUMENTATION=OFF \
  -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl \
  -DWITH_WEBSOCKETS=ON \
  -E env LDFLAGS="-L/usr/local/opt/cjson/lib -L/usr/local/opt/libwebsockets/lib" \
  -DCMAKE_C_FLAGS="-I/usr/local/opt/cjson/include -I/usr/local/opt/libwebsockets/include -I/usr/local/opt/openssl/include" \
  ../mosquitto

  编译 mosquitto-go-auth

安装依赖：

• go 编译工具，此为golang源码

pkg install go

配置国内源

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

编译

gmake
