Windows系统下使用MinGW编译paho.mqtt.c
1. 编译openssl
openssl-1.1.1k.tar.gz下载地址
1.1 编译需要使用MSYS2环境
./config
make
1.2 配置环境变量
OPENSSL_CONF = “E:\3rd\openssl-1.1.1k\apps\openssl.cnf”
OPENSSL_ROOT_DIR = “E:\3rd\openssl-1.1.1k”
2. 编译paho.mqtt.c
2.1 需要配置的环境变量
LIBRARY_PATH = “D:\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\lib”
C_INCLUDE_PATH = “D:\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\include”
2.2 他用cmake-gui创建cmake
勾选 PAHO_WITH_SSL
需要编译静态库可勾选 PATO_BUILD_STATIC
去掉勾选 PAHO_ENABLE_TESTING win32下不支持编译不过
成功Generate后
2.3 编译
2.4 修复一个错误
src/MQTTVersion.c
static const char* libraries[] = {"libpaho-mqtt3c", "libpaho-mqtt3cs", "libpaho-mqtt3a", "libpaho-mqtt3as"};
