mingw32-make[2]: *** [src\CMakeFiles\common_obj.dir\build.make:187: src/CMakeFiles/common_obj.dir/Socket.c.obj] Error 1
Log files Please try to attach log files rather than pasting the log contents. It makes the issues easier to read.
** Environment (please complete the following information):**
- OS: [Windows10]
Is poll() available in this environment? I couldn't find a list of what system calls are supported. You can use the compile definition flag USE_SELECT to revert back to select() if not.
I use Windows10 Home Edition. So poll() should be available. I also tried USE_SELECT flag. But cmake+mingw does not work correctly. But i used Visual Studio 2017 to work fine.
It appears to be related to this problem https://github.com/eclipse/paho.mqtt.cpp/issues/123

After adding poll() --> select() fix, everything worked for me:
set(PAHO_BUILD_SHARED FALSE)
set(PAHO_BUILD_STATIC TRUE)
if(MINGW)
# On Windows+MinGW 'poll()' is not supported, we need to use 'select()'
# Reference: https://github.com/eclipse/paho.mqtt.c/issues/1239
set(PAHO_USE_SELECT TRUE)
endif()
add_subdirectory(
${CMAKE_CURRENT_SOURCE_DIR}/../third_party/paho/paho.mqtt.c-1.3.13/
my_app__paho_mqtt_c
EXCLUDE_FROM_ALL
)
But during paho.mqtt.c build, I see the next warning:
[291/300 34.5/sec] Building C object my_app__paho_mqtt_c/src/CMakeFiles/paho-mqtt3a-static.dir/MQTTAsync.c.obj

This case does not affect the operation of my program (since I dont call MQTTAsync_createWithOptions) in any way, but I think the defines need to be updated here.
