Hi there, I trying to enable domain events callbacks under a cross compiled (mingwin under fedora12 env) libvirt 0.7.4 (I haven't been able to compile more recent versions under mingwin) dll. Here a little sample of code I'm trying to write : #include "stdafx.h" #include "windows.h" #include "libvirt.h" #include "virterror.h" static int domain_event(virConnectPtr conn, virDomainPtr dom, int evt, int detail, void *opaque) { bool test = true; return 0; } int _tmain(int argc, _TCHAR* argv[]) { virConnectPtr conn = virConnectOpen("qemu+tcp://192.168.220.198/session"); // Set Callback int cbresult = virConnectDomainEventRegister(conn, domain_event, NULL, NULL); // Lookup Domain virDomainPtr dom = virDomainLookupByName(conn, "Test1"); // Start Domain int startDom = virDomainCreate(dom); if (startDom != 0) { virErrorPtr e = virGetLastError(); bool test = true; } // Wait Sleep(60000); // Stop Domain int StopDom = virDomainDestroy(dom); if (StopDom != 0) { virErrorPtr e = virGetLastError(); bool test = true; } return 0; } I'm able to connect to the host and I'm able to start the domain, but when I enable callback with "virConnectDomainEventRegister", it fails, I have a message "unmarshalling msg" coming from the "remoteDomainReadEvent" method of remote_driver.c in libvirt. I think about a problem near __stdcall or __cdecl calls or this kind of thing, but I'm not sure. Any clues ? Best regards, Arnaud Champion
