[libvirt] can not connect hypervisor using libvirt-0.9.11 on windows

Hi,ALL: I compiled the libvirt-0.9.11 source code with mingw on windows according to the website: https://github.com/photron/msys_setup Then I wrote a simple test case ,as below: #include <stdio.h> #include <stdlib.h> #include "libvirt/libvirt.h" int main(int argc,char **argv) { virConnectPtr conn; conn = virConnectOpen("qemu+tcp://192.168.1.6/system"); if (conn = NULL) { fprintf(stderr,"Failed to open connection to qemu+tcp://192.168.1.6/system"); return 1; } virConnectClose(conn); return 0; } When linked to the dll just compiled , it came out with error : NOTE: you should run 'diskperf -y' to enable the disk statistics libvir: RPC error : Unable to set close-on-exec flag: No such file or directory libvir: error : invalid connection pointer in virConnectClose When using gdb to debug the testcase , break the function virConnectOpen , then step ,the error info was: Program received signal ?,Unknown signal. 0x7c92e4ff in ntdll!LdrAlternateResourcesEnabled () from C:\WINDOWS.0\system32\ntdll.dll Any suggestion would be appreciated !
