Shawn B. You are right:
My sistem has NVIDIA(r) graphics driver installed. In other  machine running fedora 4 and the NVIDIA(r) graphics driver I also found the same problem, but in a third machine with fedora 4 and without NVIDIA(r) graphics driver labview 8 installes and start.
Do you know what to do to have labview and NVIDIA(r) graphics driver running simultaneously?
Thanks: saltamontes.

hi there,

we can confirm this:

system1: SuSe 9.2 with NVIDIA(r) graphics driver: LabVIEW 8.0 won't start
system2: SuSe 9.3 without NVIDIA(r) graphics driver: LabVIEW 8.0 starts

system1: SuSe 9.2 with generic graphics driver: LabVIEW 8.0 starts

so it's not the Linux' version, it's the graphics driver.

thx all

Thanks saltamontes, and chris for confirming this.  At this point I am not aware of a way to use both the NVIDIA(r) driver and LabVIEW simultaniously.  We can notify NVIDIA of the problem with hopes that they will fix it in their next version of their driver, and I can pass this on to our LabVIEW developers who may be able to find a solution for the next version of LabVIEW.

Hi guys,
I have the same problem. I'm trying to install LabVIEW 8 on Mandrakelinux 10.1 official. LabVIEW is installed in the default /usr/local without any errors.
When I try to run it, I get about the same error as mentioned earlier ( undefined symbol _glapi_get_proc_address).
When I run
ldd -r libOSMesa.so*
in the appropriate directory I get a list of undefined symbols (sin, cos, pow, sqrt, _glapi_Dispatch, and so on) eventhough there is no NVIDIA based graphics card inside my pc.
Does anyone have a clue how to solve this?
Thanks,
Tom

hi there

please check the "LabVIEW for Linux" Readme-file for supported Linux distributions and versions and let us know (don't got our linux system at hand rigth now to check it by myself)

Hello,
Mandrakelinux 10.1 official is fully supported by NI.

Hi,

After some research, I found a solution for this problem... Because the librairies with the graphic card (either ATI or NVIDIA) don't work, I just used the following command line to start labview

LD_LIBRARY_PATH="/usr/lib/opengl/xorg-x11/lib/" labview

This forces labview to start with the libraries in the Xorg package and not the ones provided by the card driver...

I wish this can help...

Hi,
I managed to solve it. There seems to be a conflict in the libGL.so.1 that Mandrake provides.
The file /usr/X11R6/lib/libGL.so.1 should not point to /usr/X11R6/lib/libGLwrapper.so.0.2.0
This is the case when the package libMesaGL1-5.0.2-8mdk is installed from the Mandrake 10.1 CD's.
Uninstalling it restores this link to /usr/X11R6/lib/libGL.so.1.2 and everything seems to work well (even hardware acceleration through DRI) and LabVIEW can start up.
Furthermore, in the file
/usr/local/lv80/linux/README.Mesa
I found some info regarding this, but the line "...are available on the LabVIEW 6i CD-ROM in the /redist/mesa-src
directory." makes me suspicious regarding the validity of the contents of this file...
Other usefull info or remarks are still welcome!
Tom
