openclprof1.0 segfault on linux 64bit


I wanted to do some profiling of a kernel of mine, but I can’t figure out how the opencl profiling tool works: after I unzipped it, it crashes if I try to launch it.

[codebox]fedechicco@fedechicco-desktop:~/NVIDIA/openclprof1.0/bin$ echo $LD_LIBRARY_PATH


fedechicco@fedechicco-desktop:~/NVIDIA/openclprof1.0/bin$ ./openclprof

Segmentation fault



The whole thing is immidiate.

I’m working with ubuntu Karmic and the latest nvidia driver for OpenCL

[codebox]fedechicco@fedechicco-desktop:~/NVIDIA/openclprof1.0/bin$ uname -a

Linux fedechicco-desktop 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:02:26 UTC 2010 x86_64 GNU/Linux

fedechicco@fedechicco-desktop:~/NVIDIA/openclprof1.0/bin$ cat /proc/driver/nvidia/version

NVRM version: NVIDIA UNIX x86_64 Kernel Module 195.17 Mon Oct 26 06:19:11 PST 2009

GCC version: gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9)


Thank you!

I have gentoo kernel 2.6.33 64 bit
Nvidia driver 190.53-r1

cuda is working fine (with sudo)
openclprof gives segmentation fault

190.29 is the only driver opencl profiler could work with.
