Hi, I wrote a very small shared library (.so) with Eclipse (2014 toolchain), that basically acts as a wrapper for a more complex one, but I'm encountering problems with calling in from within LabVIEW RT on a Linux RT target - specifically, the cRIO 9068. First of all: the library has been copied to /usr/local/lib, and ldconfig has been properly set up. Most important, I also wrote a C program (using Eclipse as well) that calls the only function currently implemented in the shared library: this work flawlessly both under Eclipse and by logging directly on the cRIO with a Putty terminal. So I assume the shared library itself is ok and can be called from external code/programs. Now, going back to LabVIEW (2014 here btw). Here's where things get tricky, I guess. At first I had the problems listed here --> http://forums.ni.com/t5/LabVIEW/How-to-create-a-c-shared-library-so-for-linux-real-time-for/td-p/3025687 that prevented me from actually running any code on the RT target. Then I modified the Call Library Function Node: various tutorials suggest putting name_of_library.* in the library name or path text box, but this unfortunately doesn't seem to work so I had to put the actual name and extension, too. But this still produced the error below ("the function name cannot be found" etc.) So I check the "Specify path on diagram" box, and add /usr/local/lib as a parameter to the Call Library Function Node: now the VI can run and is actually transferred to the RT target... but the output error cluster returns error 7, which is a "File not found" kind of error. However, I believe this error message is misleading: indeed, if I try to remotely debug this shared library under Eclipse, I am actually able to pause it... and when I press the Pause button on the debugger, the RT target VI suspends execution, then it continue as soon as I press the Resume button, I'm stuck... I tried searching NI forums and Google as well, but I haven't still found a solution. Any ideas on what's going on? By the way, I can add more details if needed.

Problem solved, it was misconfiguration of the Call Library Function Node that prevented the actual libray (.so) from being called.
