need source for libLVMesa.so.4

[JohnNavratil]

Are the any other sources for libLVMesa.so.4 other than /usr/local/natinst/LabVIEW-8.0/linux/libLVMesa.so.4, which I do not have?  I downloaded mesa4.tar.gz, which contains mesa30lv.zip and mesa30.zip (not 4).  Did a 'make linux-elf' and and got libMesaGL.so.3.0 and libMesaGLU.so.3.0 (and links).  Where is the elusive libLVMesa.so.4?

Hi John-

I assume you've already seen the following resources based on the paths and files you referenced:

KB 3SE8TLX5: Why Does LabVIEW for Linux Return Error "symbol lookup error: libOSMesa.so.4: undefined...

Discussion Forum: The libOSMesa nightmare

libOSMesa.so.4 depends on libGL.so.1. Sometimes the libGL.so.1 found in /usr/lib/ does not contain the _glapi_Context function. NI provides a version of this library as well.

cd /usr/local/natinst/LabVIEW-8.2/patchlib/
ln -s libGL.so.1.2 libGL.so.1

running "ls -l" should look something like this:

     total 261
     lrwxrwxrwx 1 root root 12 Oct 12 17:53 libGL.so.1 -> libGL.so.1.2*
     -r-xr-xr-x 1 root root 264864 Jun 15 17:50 libGL.so.1.2*
     lrwxrwxrwx 1 root root 23 Oct 12 18:36 libOSMesa.so.4 -> ../linux/libOSMesa.so.4*
     -r--r--r-- 1 root root 675 Jul 31 11:30 README.NVidia

If this doesn't fix your problem, please reply and attach the output of "ldd -r labview".  Thanks!

The problem is that I don't have LabView.  My /usr/lib contains:

lrwxrwxrwx 1 root root     10 Dec 28 11:21 libGL.so -> libGL.so.1
lrwxrwxrwx 1 root root     12 Sep 14  2006 libGL.so.1 -> libGL.so.1.2
-rwxr-xr-x 1 root root 389588 Jun 26  2006 libGL.so.1.2

But, at any rate, as my goal is to drive a very simple control system using the low level C api, I am no pursuing this problem at the moment.  Of course, I may need to revisit this as my knowledge of the problem advances.
