using the shared object

• Cannot bind to the shared object created with LabVIEW 2009

  I have problems referring to a shared library built from a LabVIEW VI under RHEL 5 with LabVIEW 2009.

  To illustrate the problem, I created a VI with a digital input and output that corresponds to a certain number. Then, I created a draft specification of build to create a shared library with a feature that makes use of this VI square. The shared object is created successfully (square.so).

  When I try to compile a test application written in C, that connects to this library, I get errors in the following link:

  cc  -I/usr/local/natinst/nidaqmxbase/include -I/usr/local/natinst/LabVIEW-2009/cintools build/square.so  test.c   -o test/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(float&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(double&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(double&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_ostream >& std::basic_ostream >::_M_insert(double)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(float&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_ostream >& std::basic_ostream >::_M_insert(double)@GLIBCXX_3.4.9'collect2: ld returned 1 exit statusmake: *** [test] Error 1
  

  Running ldd reveals that liblvrtdark.so.9.0 is used for the execution of labview.

  In order to investigate on what could be the cause of the problem, I have compiled the nidaqmx basic examples, and I don't have an error. Current running ldd as reveals that he uses liblvrtdark.so.8.2 for the view of laboratory, time of execution.

  My suspicion is that some components of labview are being compiled with gcc 3.4 while others are being compiled with gcc 4.1 (which is the default compiler in RHEL 5).

  Any ideas how I could fix the build errors?

  Thanks in advance for your suggestions.

  PS.

  I enclose a tar file with the source files and here are the details of the ldd:

  Hi mimi,

  I'm happy to report that I managed to get the code to work. I have included some of the steps I experienced the problem in case it might help improve the documentation or future generations.

  In response to your question about the "error 1" reported by do, it's just an indication that detected a compiler error (it probably resembles the return code of the compiler).

  The errors ' undefined reference... @GLIBCXX_3.4.9 "have been narrowed down. The generated labview shared library, the square.so, links to /usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6 which is a symlink to usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6.0.9. I decided to compare this version of libstdc ++ that included with RHEL:

  strings /usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6 | grep GLIBCXXGLIBCXX_3.4GLIBCXX_3.4.1GLIBCXX_3.4.2GLIBCXX_3.4.3GLIBCXX_3.4.4GLIBCXX_3.4.5GLIBCXX_3.4.6GLIBCXX_3.4.7GLIBCXX_3.4.8GLIBCXX_3.4.9GLIBCXX_FORCE_NEW
  

  strings /usr/lib/libstdc++.so.6 | grep GLIBCXXGLIBCXX_3.4GLIBCXX_3.4.1GLIBCXX_3.4.2GLIBCXX_3.4.3GLIBCXX_3.4.4GLIBCXX_3.4.5GLIBCXX_3.4.6GLIBCXX_3.4.7GLIBCXX_3.4.8GLIBCXX_FORCE_NEW
  

  So libstdc ++ RedHat does not include a string for GLIBCXX_3.4.9.

  With this in mind, I was able to get my test application to compile using the version of LabVIEW libstdc ++ using the following makefile:

  .PHONY: all cleanCPPFLAGS=-I/usr/local/natinst/nidaqmxbase/include -I/usr/local/natinst/LabVIEW-2009/cintoolsLDFLAGS=build/square.so \        /usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6 \        -Wl,--rpath -Wl,/usr/local/lib/LabVIEW-2009/patchlib/
  
  all: test
  
  clean:        rm -f test *.o
  

  When you try to run the application, I got the following error:

  ./test: error while loading shared libraries: /usr/local/lib/liblvrtdark.so.9.0: cannot restore segment prot after reloc: Permission denied
  

  But apparently, it's because of SELinux prohibiting the use of libraries shared with moving text.
  This can be disabled by running /usr/sbin/setenforce 0 as root.

  The test application now works!

  See you soon,.

• How to use the Credential object?

  I had an obligation to create a password confirmation form in vCO. I detailed what I came here:

  http://www.jonathanmedd.NET/2015/01/presenting-a-password-confirmation-form-in-VCO-VRO.html

  It has been suggested in the comments that:

  "A better solution would be to use an entry of type 'credential' (which includes natively password confirmation checking)."

  Although the credential object solves the problem of the confirmation of the password very well, she introduced a new show that I fight to manipulate its contents when you work in the workflow using as input.

  I tried to use the credentials object once before, but he had problems with the password property. Once the workflow, the password property is not currently available. The API Explorer for the password property indicates "[obsolete] passwords are not available in the script". For example, I want to use the credentials with the "Execution of the Guest program" workflow, I need to provide a username (String) and the password (SecureString), but just picking on the properties username and password of the credentials object does not. I can confirm in the workflow using the method checkPassword that the password matches a known value. However, when you try to use the password property and assign a different workflow requiring password authentication always fails.

  Does anyone have examples of use of the object of identification information on the work plan with the password in the workflow in script tasks or other work streams?

  Thank you :-)

  I didn't know that this was the case.

  It was definitely a fix to avoid someone making a server.getCredential () in a workflow to steal user passwords.

  If the credential object can only serve to set methods taking as parameter.

  You will need to find a forum for MS Word, since it is the software you are trying to manipulate in the present.  If you think that the treatment/creation of the PDF file plays a role, then you should ask in the forum for the software that you use to create the PDF file.

• Deploy and use the shared library in VeriStand for several VCD

  Hello world

  I'm using LabVIEW 2011 SP1 and VeriStand 2011 SP1.

  We have developed many custom features that use a shared code (C++ and LabVIEW code).

  For now, there is a copy of the C++ shared in each custom device dll.

  The problem is when we change the C++ dll and we forget to copy a new one to each custom devices, the oldest one that can be used by each custom devices.

  We would like to do is not to have only a single dll shared in a specific folder.

  My questions are how we can deploy this dll to a specific shared folder in VeriStand?

  Is there a specific folder that we can use to do this?

  Is it possible to deploy using the measurement and Automation Explorer?

  If someone has an idea, you are welcome!

  Best regards

  CFOE

  You can display this question in another forum that I don't think there's anything directly to do with NI VeriStand.

• ATEs by using the shared but sequence having separate databases

  They just showed me two ATEs that use a common test sequence stored on a network server.  It is desirable that both connect their results to different data bases MS Access, but changing the connection string Expression to an ETA updates the Database Options on the other.

  Is it possible to share a movie file, but newspaper results from each ATE in different databases?

  

  Hi Jim,.

  To do this, you can add the ProcessModel DatabaseOptions callback sequence to the same sequence as your MainSequence file, and then programmatically set the Parameters.DatabaseOptions.ConnectionString based on who ATE called the shared sequence. This assumes that your shared movie file uses a process template.

• Publish a queue using the shared variable

  I have a 2D table queue and I would like to publish (the reference) in a shared variable, so that I can pay the items in the queue in an another vi. I tried to create a queue control and used the custom of the shared variable control option, but it gives me an error "invalid data type.

  You try to read from the queue to another computer? Passing the reference to the queue on the network to a another computer will not allow the application to read data from the queue. The queue data is stored only locally.

  I honestly don't know why you get an error trying, however. Other options to access a queue in the world on the same machine are to use a Global Variable, rather than a shared Variable, or to get your reference queue by using a well-known name who know the other parties of the request.

• Taskflow have model (using the view object instances) of two data sources

• using the JavaScript object and flow

  Two problems:

  Problem 1

  I'm trying to understand the best way to manage a service on the attached form (the form is under construction and messy!).

  There is a requirement to attach files to the form. I have it understood, but would like to cope better. There are about 8 places to attach files, and each time I move things around I need to change the code for each button, so I think that function in a script object implementation is the way to go (let me know if there is a better way!).

  I think I've learned how to work the script objects, but have not tried this although there are has a few pieces I could not understand yet.

  The way it works now, it's you click on the button to fixation, attach a file and the file name is entered in the field surrounding the button - there is a separate field around each button (see subform "subProjectInfo.subAttach" on page 2). What I can't understand, it is if I put this in a function/script object, how do I get the name of the file in the appropriate box? I have to return the data back to the button, I guess, which can then fill in the field?

  
  Problem 2

  At the bottom of the same page (2) is a subform (subProjectInfo.subMilestones) with a table in full expansion. I followed the example in the purchase order example, but I can't get the headers to repeat correctly. When it breaks to a new page, the header above is repeated whenever a row is added.

  Extra bonus question!

  I hope one of you more knowledgeable guys can take a look at the structure of the form and let me know what it feels like to a 'best practices' point of view - use of subforms, that sort of thing. I use a lot of subforms to wrap things and have been wondering about the performance, that kind of thing. This is the most complex form, I've done so far and want to make sure that I'm going down the correct road!

  Hi Jono,

  Hopefully, I've solved your problem 2, I deleted simoly repeat for each item in the MilestoneHeader.GeaderRow [0]. And now it is only repeated for new pages.

  When I have time, I'll try to check your problem 1.

  In the package where the VO is defined, there should be a file server.xml file that contains all the BC4J objects. You can then add this file to your project in JDeveloper and it will add all the your defined in the file.
