Hi ppl, I have a problem when running an executable, it seems that is running fine, but I don't get any output in the console.
I need to build the [Paho MQQT Client](https://eclipse.org/paho/clients/c/) in Cygwin. So I modified the Makefile in order to build .dll instead of .so files. I have attached the changes I made to the Makefile(Makefile_cygwin.patch). I followed the instructions [here](https://cygwin.com/cygwin-ug-net/dll.html) for the dll. The client comes with some sample applications, so I tried to run one of them, MQTTAsync_publish.exe. I would expect to get the following output (I run it in a linux box) $ Waiting for publication of Hello World! $ on topic MQTT Examples for client with ClientID: ExampleClientPub $ Connect failed, rc 0 but I don't get anything in the console and the application seems to run without any other output or any indication. First I thought that I hadn't linked correctly the dll, but I executed the following $ cygcheck.exe ./MQTTAsync_publish.exe C:\cygwin64-fresh\home\svagionitis\workspace\org.eclipse.paho.mqtt.c.git\build\output\samples\MQTTAsync_publish.exe C:\cygwin64-fresh\bin\cygwin1.dll C:\Windows\system32\KERNEL32.dll C:\Windows\system32\API-MS-Win-Core-RtlSupport-L1-1-0.dll C:\Windows\system32\ntdll.dll C:\Windows\system32\KERNELBASE.dll C:\Windows\system32\API-MS-Win-Core-ProcessThreads-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Heap-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Memory-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Handle-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Synch-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-File-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-IO-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-ThreadPool-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-LibraryLoader-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-NamedPipe-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Misc-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-SysInfo-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Localization-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-ProcessEnvironment-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-String-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Debug-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-ErrorHandling-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Fibers-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Util-L1-1-0.dll C:\Windows\system32\API-MS-Win-Core-Profile-L1-1-0.dll C:\Windows\system32\API-MS-Win-Security-Base-L1-1-0.dll C:\cygwin64-fresh\usr\local\lib\cygpaho-mqtt3a.dll.1.0 and it seems that the library is there. I have installed all the produced libraries in the /usr/local/lib and I have added the /usr/local/lib to the PATH. I am not sure what might be the problem, is it something related to the output or something else? I am open to any suggestions of how to pinpoint the problem. Thank you in advance. Regards, Stavros P.S. I have attached the cygcheck.out for more info of the system.
