Can I use shared libraries such as lvanlys.dll for matrix inversion on a sbRIO device?

I tried FTP transfer the dll file to the RIO device. the RT MPU.vi can run without error. But the library does not appear to be called.

Since the sbRIO RT controller is running VxWorks, you can only call .out files through the Call Library Function Node. Here are a few good resources pertaining to your question that you may find helpful:

Daniel,

Thank you for your reply. I do find the .out file in the ~/ni-rt/system/ folder. However, when I try to call it using the call library function node, call lvanlys.out for example, I still get the "Failed to load shared library lvanlys.*:CxInvMatrixLUDri_head:C. Ensure that the library is present on the RT target..." error message. Any idea why this is happening?

Are you able to call any .out files on the RT controller? Or is it just the lvanlys.out file that is giving us trouble?

I worked through the examples online and I can call the fib.out library that I create and transfer to the ni-rt/system folder. However, I cannot call the .out files that is originally in that folder, such as the lvanlys.out.
