Labview crashed on Mac OS X Sierra: 'nextEventMatchingMask should only be called from the Main Thread!'

[qizheng_square]

Thank you for taking time looking into this issue.

My testing environment has mac only, so I have to stay with OS X. I need to get the company approval on Budget to switch to Windows.

[mterz]

Sorry it has taken me awhile to get back. I did not have my Mac with me. What software are you using for your coding?

[qizheng_square]

Are you asking about the IDE? If so, I am using the Xcode command line tools.

[DET-POLITO]

Dear all, I am expariencing the same problems. You can use this to reproduce the error. Hope this can help. My compute is a MacBook Pro 15" just bought with Sierra and Nidaqmx base 15.

I used the examples provided by NI in the ai subfolder with an USB 6216 which is correctly recognized by lsdaq

NI USB-6216: "Dev1"    (USB0::0x3923::0x733B::0166EF64::RAW)

The example compiles without problems

gcc -O2 -arch x86_64 -F/Library/Frameworks -Wno-format  -framework nidaqmxbase -framework nidaqmxbaselv acquireNScan.c -o nScan

but when I run it I get the error

Do you have any luck resolving this issue. After upgrading to sierra, the previous compiled examples are working, however if I compile new ones they crash with the same error:

No, no luck at all. so I stopped using NI's product. I suggest to use MCC DAQ, which uses open-source libusb and libhid, and works way better.

[swapcool]

Hey I am facing the same error on my macos high sierra 10.13.3

Any solutions?

And what is the alternative API for macos?

mcd daq does not seem to have macos support

[Brian.D]

If you are using NI-DAQmx Base 15, Mac OS X 10.13.13 is not officially supported (see the description tab): http://www.ni.com/download/ni-daqmx-base-15.0/5648/en/.

What version of LabVIEW are you using? LabVIEW 2017 SP1 does support Mac OS 10.13.

Lastly, even though you are encountering a similar issue, you may gain more visibility by creating a new forum post.

I have the same problem with High Sierra. This simple program produces the same error message.

#include <stdio.h>
#include <NIDAQmxBase.h>
  
  int main(void) {
      TaskHandle task;
      int ret_code;
  
      ret_code = DAQmxBaseCreateTask("", &task);
      printf("ret_code = %d\n", ret_code);
      return 0;
  }

Result:

I have found some additional information. If the same code is compiled with -arch i386, then I get a warning but it does not crash and appears to work.

Here is the warning:

2019-02-18 14:15:18.868 Essai32[4872:81953] pid(4872)/euid(501) is calling TIS/TSM in non-main thread environment, ERROR : This is NOT allowed. Please call TIS/TSM in main thread!!!

Any idea why the discrepency between 32-bits and 64-bits libraries ?
