Sementation Violation on Samples

[arcfide]

I am having some trouble with getting copperhead up and running. I don't see a mailing list or some other method, so I am submitting the issue here. Here is the output of a backtrace on the python process that gives me the segmentation violation:

(gdb) run black_scholes.py
Starting program: /usr/bin/python black_scholes.py
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?

This is on a Slackware64 14.0 box running on a Geforce GTX 675m card with Cuda 5.0. I have been able to run the Cuda examples and samples without problems so far. My installation of copperhead went as follows:

1. Install Thrust over Cuda 5.0 headers.
2. Install Scons.
3. Install numpy
4. Enable GCC 4.6.3 (Slackware64 14.0 uses GCC 4.7 by default)
5. Enable Cuda.
6. Run python setup.py install

This all seemed to go through without too many problems once I installed the Thrust, numpy, and Scons dependencies. Running python setup.py test seems to run and no errors are reported, but the last line of output is 'running tests'.

After doing this, I note that the example given on the homepage, the sample programs (I ran black_scholes.py), and any of the tests give me the same segmentation violation. I have tried running the homepage sample, the black_scholes.py example, and the test_all.py program inside of tests/. Each of these gives the same sort of backtrace as above, but the black_scholes.py program is given above. I assume that I am correct in trying to run them by running python black_scholes.py and so on.

I am not a Python programmer, so I could be really messing something up here, but I would appreciate whatever assistance you could provide in setting this up.

I should also note that the Boost library is installed by default in Slackware and presumably is compiled using the GCC 4.7 compiler family.

Hello,

I cannot tell for sure what is going on in your environment, despite I already saw some similar problems. It's clear to me that you are aware of several tricks involved in the build process. So, I will point out a blog entry I've written which, I hope, eventually will provide some detail you may be missing.

I hope it helps.
