First error message arises in step 4: > "TSocket::write_partial() send() <Host: my_host Port: 9090>Broken pipe" I strongly suggest placing communication service in its own thread. Then you could manage connection without having to worry about blocking timeouts caused by GUI operations. They will run asynchronously. > On a Linux box the client program runs perfectly. Only by coincidence, I suppose. > On the windows box the program works, if i initalize Qt before the > connection to the server is made (step 2 before step 1). But that is not > acceptable for me, because afterwards other widgets and buttons are created > and i can not close and create the connection at each point. I suppose, the server dropping connection by timeout. But I'd urge you to investigate this further. > For the tests I used the examples from the Apache Thrift Tutorial. Please include examples as text/plain attachments, if they are longer than a few lines. -- With best regards, Andrey Repin Wednesday, March 25, 2020 14:08:25 Sorry for my terrible english... -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
