Errors with running executable

[vaku]

Hi all,

I'm having trouble with running an executable under LabView 8.2.1. My system runs CentOS 5.4. I made a simple vi and built it as an executable. When I tried to run it though, it wouldn't run. The following error was generated:

Can't load LabVIEW runtime library /usr/local/lib/liblvrt.so.8.2

/usr/local/lib/LabView-8.2/linux/libOSMesa.so.4: cannot restore segment prot after reloc: Permission denied

The pointer on the first line points to the correct file. libOSMesa.so.4 has permission set to 644.

The vi is a simple data collection using VISA. Any ideas to fix this will be appreciated. Thanks!

Have you installed the runtime engine? Does the system you are trying to run this have visa and lv installed?

Hello,

Can you build and run executables that do not rely on a driver? The readme for LabVIEW for Linux 8.2.1 states: "LabVIEW 8.2.1 runs on Red Hat Enterprise Linux WS 3, SuSE Linux Professional 9.1, and Mandrake Linux 10.0 or later. LabVIEW can run without hardware driver support on any other distributions that provide GNU C Library (glibc, also known as libc.so.6) Version 2.2.4 or later."

Hi,

thanks for the replies. I have the run-time engine installed, or so I thought, because otherwise I wouldn't have those files, right? How would I check for sure that I have the runtime engine and lv? When I tried the compile the vi, there were no errors generated, so I assumed that everything was in order.

I have glibc installed already, version is 2.5-42. Are there specific things I should do to build the executable that doesn't depend on hardware driver support? (FYI, CentOS 5.4 ought to be functionally equivalent to RHEL 5.4... so I am technically running one of the officially-supported distributions)

Hello,

You will need to use whichever package manager application you have to see what is installed on your Linux machine. The steps outlined in the knowledgebase are useful as a general guide: http://digital.ni.com/public.nsf/allkb/2266B58A5061E86A8625758C007A4FE3 .
