Dear Mr. Bernard,
Bonjour!
I am trying to set up miniupnpc with qt, following http://mayaposch.wordpress.com/2011/09/18/setting-up-miniupnpc-with-qt/, as you mentioned in a previous topic.
I am using Qt5.8.0 (qt-opensource-windows-x86-mingw530-5.8.0), in win7 x64.
I have downloaded miniupnpc-1.9.20150917.tar.gz and upnpc-exe-win32-20150918.zip，and extracted them to C:\miniupnpctest\miniupnpc-1.9.20150917 and C:\miniupnpctest\upnpc-exe-win32-20150918.
I put the below in the qt main.cpp,
| Code: |
#include <miniupnpc.h>
|
| Code: |
const char * multicastif = 0;
const char * minissdpdpath = 0;
struct UPNPDev * devlist = 0;
unsigned char ttl = 0;
int error = 0;
devlist = upnpDiscover(2000, multicastif, minissdpdpath, 0, 0, ttl, &error);
|
In the qt *.pro,
| Code: |
INCLUDEPATH += C:\miniupnpctest\miniupnpc-1.9.20150917
LIBS += C:\miniupnpctest\upnpc-exe-win32-20150918\libminiupnpc.a
LIBS += -liphlpapi
|
and result in error:
| Code: |
error: undefined reference to `_imp__upnpDiscover'
|
It seems that the link to *.a was wrong.
How could I fix this problem?
(I also took a try to copy libminiupnpc.a to C:\Qt\Qt5.8.0\5.8\mingw53_32\lib or C:\Qt\Qt5.8.0\Tools\mingw530_32\lib, and change *.pro to be LIBS += -lminiupnpc, but it result in the same error.)
Thank you!
Yours sincerely,
Jason |

I have set up qt creator 2.1.0, qt 4.7.4 in C:\Qt, in winxp, and set ENV. PATH to be C:\Qt\qtcreator-2.1.0\mingw\bin. and make all above work well.
I have compiled miniupnpc-1.6 succesfully in c:\miniupnpc-1.6, by using mingw32make.bat, with the mingw mentioned above.
I put the code in the qt main.cpp
| Code: |
#include "dialog.h"
#include <QApplication>
#include <QDebug>
#include <miniupnpc.h>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Dialog w;
w.show();
const char * multicastif = 0;
const char * minissdpdpath = 0;
struct UPNPDev * devlist = 0;
int error = 0;
devlist = upnpDiscover(2000, multicastif, minissdpdpath, 0, 0, &error);
if (devlist)
{
qDebug() << "devlist true!" << endl;
struct UPNPDev * dev;
dev = devlist;
while (dev)
{
if (strstr (dev->st, "InternetGatewayDevice"))
break;
dev = dev->pNext;
}
if (!dev)
dev = devlist; /* defaulting to first device */
qDebug("UPnP device :\n"
" desc: %s\n st: %s\n",
dev->descURL, dev->st);
}
else
{
qDebug() << "devlist false!" << endl;
}
return a.exec();
}
|
In the test1.pro:
| Code: |
QT += core gui
TARGET = test1
TEMPLATE = app
INCLUDEPATH += C:\miniupnpc-1.6\
LIBS += C:\miniupnpc-1.6\libminiupnpc.a
LIBS += -liphlpapi
SOURCES += main.cpp\
dialog.cpp
HEADERS += dialog.h
|
But it still result in:
| Code: |
error:undefined reference to `_imp__upnpDiscover'
|
and I copied "libminiupnpc.a" to C:\Qt\qtcreator-2.1.0\mingw\lib, and change the *.pro to be
| Code: |
INCLUDEPATH += C:\miniupnpc-1.6\
LIBS += -lminiupnpc
LIBS += -liphlpapi
|
and result in the same error.
This is quite strange, could anyone help me?
Thank you very much! |

work well in winxp, win7 and linux, with different version of qt.
just code:
| Code: |
DEFINES += STATICLIB
INCLUDEPATH += F:\vmshare\miniupnpc-1.6-success
LIBS += F:\vmshare\miniupnpc-1.6-success\libminiupnpc.a
LIBS += -liphlpapi
LIBS += -lws2_32

just define MINIUPNP_STATICLIB if you link against the static library

DEFINES += STATICLIB help my simple test qt project compiled successfully and work well, but it didn't work with my complicated qt project, meeting problems like "miniupnpc.c:-1: error: undefined reference to `in6addr_any'.
Thanks to your replies, I took a try to define MINIUPNP_STATICLIB, and It works very well.
I don't know why it work well, hope I can find it out someday.
Thank you again! |
