Linux app builder hangs with daqmxbase 1.5.0-f2

[Ryan_V[DE]]

BR,

I've confirmed that this is a known issue in 7.0 and the only workaround is to upgrade to 7.1. On a side note, some people are able to successfully build applications after a restart. I apologize for this inconvenience, but upgrading appears to be your only option. Good luck!

Hi all, I've the same problem with LV7.1/DaqMX1.5.

I need to read voltages from a PCI-6023E/6024E  card.

With the box "Disconnect type definitions and remove unused polymorphic VI instances" checked, app builder hangs and I must kill LV.
With the same control unchecked the build hangs for a while (one minute or so), then returns an error:

    Error 1003 at .../LabVIEW Data/app/internal llb/67xx--Board Config.vi

    Possible reasons
    LabVIEW: the VI is not executable.

- Application runs fine in LV environment
- The same app is compiled with no problems on Windows
- Other apps that don't use DaqMX are compiled on Linux.

Any Idea?

Thanks for support.

Regards.

GV,

There are several things that can cause this error. Do you have two VIs with the name 67xx--Board Config.vi? If you open this VI directly, is the run arrow broken? You should try a forced recompile (ctrl+shift+run arrow) on your main VI to see if that breaks your run arrow. If it does, then you can find the source of the problem. Please have a look at this KnowledgeBase article for more information.

Hope this helps,

Thanks for the answer.-

Do you mean in the appbuilder vi list? I have only one instance of that vi (67xx--Board Config.vi) there; but my application gets voltages (AI) and controls a digital line (dig output); with all the sub vi requested by the DaqMX libraries it's (for me at least) pretty complex and I can't track how many times that vi is called.

I've extracted the vi (67xx--Board Config) from the library, and tried to run alone; the vi is executable (run arrow not broken); "ctrl+shift+run arrow" doesn't break the run arrow, and vi remains executable (tested either in normal and debug mode).
Building this vi behaves the way it does with my app: hangs forever or returns 1003 error; after build failure vi is still executable.
In the block diagram, there are two sub vi (board reset and channel config), a for loop and 2 invoke node.
Each sub vi executes and build successfully.


Have you any other idea?

Thanks.

Regards.

GV,

Have you tried a mass compile (Tools->Advanced->Mass Compile) on your vi.lib folder (/usr/local/lv71/vi.lib)? What linux distribution are you using? Have you been able to compile any of the DAQmx shipping examples?

Thanks,

[gaimppi]

I tried a mass compile, but I'm not sure of the results...
The compiler ends with no message (neither 'error' nor 'done') and the folder I selected seems totally unaffected; no new file were created, but I didn't use mass compile before, and I don't know exactliy what MC does.

The OS is Scientific Linux 3.0.2; I have no administrator rights, so when I try to compile examples, I get a 'File permission error'; if I copy examples iin my folder the build behavior is the same of my app (hang or error 1003).

Waiting for the admin to make some other test with administrator rights.

Thanks.

GV,

I would certainly try testing with administrator privelages. Additionally, your Linux distribution is not one supported by National Instruments. If you can't get things to work with Scientific Linux, I would try another distro. For more information on supported distributions and other frequently asked questions, please check here.

Hope this helps,
