Error compiling Protonect in qtcreator

[ttsesm]

Hi guys, many thanks for your efforts to provide us the library. I have followed and finished successfully the procedure for installing libfreenect2 library in windows 8 through the README. Moreover, if I run the built Protonect.exe from command line it gives me without problem the output from the 4 views. However, I tried now to compile and run the Protonect example by copying the source and another one of mine through qtcreator and while it compiles if I try to run it, it gives the following error:

[Info] [Freenect2Impl] enumerating devices... [Info] [Freenect2Impl] 12 usb devices connected [Info] [Freenect2Impl] found valid Kinect v2 @1:6 with serial 014947350647 [Info] [Freenect2Impl] found 1 devices [Info] [Freenect2DeviceImpl] opening...

[Error] [RgbPacketStreamParser] packetsize or sequence doesn't match! [Info] [Freenect2DeviceImpl] started The program has unexpectedly finished.

also in the terminal of qtcreator I am getting the following message:

can you understand what might be the problem. Thank you for your time.

Update: ok it seems that I am getting the above error also when I run the Protonect.exe example that it has been built with the libfreenect2 library. However, this does not seem to prevent from showing the output. Any clues about what is happening? From what I noticed from my example is also that it cannot acquire the serial number of the device though from the above output it says that it found it.

Also another question is which libraries do I need to include in my project? is it libfreenect2.lib enough or I need also glfw3dll.lib, libusb-1.0.lib, turbojpeg.lib, OpenCL.lib, and opengl32.lib as well in addition with the corresponding include folders. Sorry for the naive questions but I am trying to be sure and limit down the possible causes.

The program has unexpectedly finished.

For this error, you can run Protonect from Visual Studio and catch the error.

I don't see anything wrong in your qtcreator messages. Protonect itself depends on libfreenect2.lib and glfw3dll.lib (if you use OpenGL viewer here).

Hi @xlz, thanks for the reply. After following your advice and trying to deploy Protonect in Visual Studio line by line it seems that the following line causes the problem:

std::string serial = freenect2.getDefaultDeviceSerialNumber();

running the debugger it gives me the following message:

Unhandled exception at 0x00007FFD8D8AD164 (msvcr120d.dll) in Protonect.exe: 0xC0000005: >Access violation reading location 0xFFFFFFFFFFFFFFFF.

Protonect.exe!std::allocator::deallocate(char * _Ptr, unsigned int64 formal) Line 574 C++

I do not know does that gives you any clue what might be the problem?

---

Update:

Also another thing that I noticed is that even if I pass manually the serial number std::string serial = "014947350647"; the following code:

if (pipeline)
    {
        /// [open]
        dev = freenect2.openDevice(serial, pipeline);
        /// [open]
    }
    else
    {
        dev = freenect2.openDevice(serial);
    }

    if (dev == 0)
    {
        std::cout << "failure opening device!" << std::endl;
        return -1;
    }

gives me failure opening the device.

[xlz]

Unhandled exception at 0x00007FFD8D8AD164 is probably just failure to get the serial number string. I think there is some known bug here that does not parse the string correctly, but it's not the problem for you.

Anyway, you are having usb problems. You can set environment variables LIBUSB_DEBUG=3, and run Protonect.exe 014947350647 and see what is the error.

[ttsesm]

Hi @xlz setting the environment variable LIBUSB_DEBUG=4 as you said I got the following output:

$ ./Protonect.exe 014947350647 hello world! Environment variables: LOGFILE= Usage: C:\Users\userKinect\Documents\Visual Studio 2013\Projects\Protonect\x64\Debug\Protonect.exe [gl | cl | cpu] [] [-noviewer] [Info] [Freenect2Impl] enumerating devices...

do you see something wrong?

[ttsesm]

But I was wondering why the Protonect.exe compiled together with the library in the beginning runs without a problem and the customized project from visual studio or qtcreator using the compiled libfreenect2 driver does not. If it is a usb problem as you say I should had problem in both cases, shouldn't I?

[xlz]

I thought you reported

it seems that I am getting the above error also when I run the Protonect.exe example that it has been built with the libfreenect2 library

?

OK, it seems it is not a usb problem. "failure opening device" happened because the default serial number was different than expected. It is still something wrong with std::string.

I think it is this http://stackoverflow.com/questions/2322095/why-does-this-program-crash-passing-of-stdstring-between-dlls

Hi @xlz thanks for the feedback and the link. Just for verification in the beginning I was getting the following error:

[Error] [RgbPacketStreamParser] packetsize or sequence doesn't match!

only in the customized project. But afterwards in both cases but I guess it might had to do with the problem explained in the link you pointed me out.

Now regarding the actual issue changing from debug mode to release mode in my custom visual studio project seems to solve the problem. However, does that mean that I cannot compile my custom projects in debug mode? Actually if I understood correctly this is happening because libfreenect2 is compiled in release mode right? Will I need to recompile libfreenect2 in debug mode?

[xlz]

You were using Release mode qt libraries with Debug mode libfreenect2 and that was the problem. If you want to use Debug mode lilbfreenect2, you will need Debug mode qt libraries.

Hi @xlz thanks for the feedback. Well, problem seems to be solved so I will close it. Thanks again for the help.
