Hello DTN!

I've been running iqconnect.exe just fine under wine, with an X11server for gui, until recently it stopped working. When I investigated, I see it throwing an exception inside zeromq.cpp:

Assertion failed: Socket operation on non-socket (C:\Source\IQClient\Shared\third_party\zeromq\zeromq-4.0.5\src\select.cpp:170

It appears there may be a bad cast in the code -- see the stackoverflow below.

Or perhaps there is another reason for this?

Please advise. Thank you.

Given ZeroMQ API / C++ binding documentation recommends to do so, one ought follow a practice to:

To obtain a ØMQ socket for use in a zmq_pollitem_t structure, you should cast an instance of the socket_t class to (void *).

comment:
I've always thought that this is a nasty little thing in the C++ bindings. It relies on the first member variable in the zmq::socket_t class being the C zm\
q socket. If you edit the definition of zmq::socket_t to change the member variable order it breaks stuff, badly. –

Good to know, thanks for user3666197's answer. Although cast an object to a void* pointer making me feel weired zmq reference with an example –

comment:
Instead of C-style casting you can use socket_t::operator void*() explicitly –

Ah. I see from the zeromq socket.cpp line number indicated that problem has nothing to do with the stack overflow issue which is distinct and so should be ignored; from reading the zeromq source:
https://github.com/zeromq/libzmq/blob/538e5d47421f45d88a8b3b005ed9ee4026623a7b/src/select.cpp#L170

Anyway. I'm on ubuntu 18.04 using Wine 3.6.1, specifically:

ii fonts-wine 3.0-1ubuntu1 all Windows API implementation - fonts
ii libkwineffects11:amd64 4:5.12.9.1-0ubuntu0.1 amd64 KDE window manager effects library
ii libwine-development:amd64 3.6-1 amd64 Windows API implementation - library
ii libwine-development:i386 3.6-1 i386 Windows API implementation - library
ii playonlinux 4.3.4 all This program is a front-end for wine.
ii wine-development 3.6-1 all Windows API implementation - standard suite
ii wine32-development:i386 3.6-1 i386 Windows API implementation - 32-bit binary loader
ii wine64-development 3.6-1 amd64 Windows API implementation - 64-bit binary loader
ii winetricks 0.0+20180217-1 all package manager for Wine to install software easily

nevermind. I'm not sure what the root cause was, but it seems to be related to X11 stuff under wine and not to iqconnect.

root cause was: Xvfb-run will fill up the /tmp/X$i-lock files and then quietly send your X session into garbage land. I now avoid Xvfb-run and just figure out a free DISPLAY for Xvfb myself and then everything works again. Avoid Xvfb-run is my recommendation; its a garbage bash script. Just use Xvfb directly.
