undefined symbol error
by Chris
Hey Andreas,
I am having a similar issue that Kambiz Tavabi was having. Here is the error
(I have pycuda on anaconda2 just like Kambiz)
File "main_class.py", line 17, in <module>
import pycuda.gl as cuda_gl
File
"/home/uchytilc/anaconda2/lib/python2.7/site-packages/pycuda-2016.1.2-py2.7-linux-x86_64.egg/pycuda/gl/__init__.py",
line 2, in <module>
import pycuda._driver as _drv
ImportError:
/home/uchytilc/anaconda2/lib/python2.7/site-packages/pycuda-2016.1.2-py2.7-linux-x86_64.egg/pycuda/_driver.so:
undefined symbol: _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEED1Ev
The weird thing is that I have some files that are having this problem and
some that are not, with identical import statements.
import sys
from OpenGL.GL import *
from OpenGL.GLUT import *
from OpenGL.GLU import *
from OpenGL.GL.ARB.vertex_buffer_object import *
from OpenGL.GL.ARB.pixel_buffer_object import *
import pycuda.gl as cuda_gl
import pycuda.driver as cuda_driver
The files that are experiencing this issue are all files that run this
import statement right at the top in the main.py file, the one I initialize
from. The one that doesn't hit this error has the import statements in a
second file that is being imported with an __init__.py file. Not sure if
this is pure coincidence or not but I figured it was worth bringing up.

Installation on Ubuntu 14.04

Hi,
I'm trying to install pyCuda 2016.1.2 on Mint 17.3 (same as Ubuntu 14.04),
I follow the procedure found at
https://wiki.tiker.net/PyCuda/Installation/Linux/Ubuntu, but I keep having
the same error
In file included from src/cpp/cuda.cpp:1:0:
src/cpp/cuda.hpp:14:18: fatal error: cuda.h: No such file or directory

Fixed in git, but not yet released:

Thanks for the report,

CUDA driver compute mode
by Kambiz Tavabi
Following TB from test_driver.py with 2016.1.2 build on OS X 10.11 with
CUDA 8 V8.0.61; was able to workaround by changing
if drv.Context.get_device().compute_mode == drv.compute_mode.*EXCLUSIVE*:
to
if drv.Context.get_device().compute_mode == drv.compute_mode.
*EXCLUSIVE_PROCESS*:
in test_dirver.py
Is this expected?

In theory it's possible.
But according to Debian Policy 2.2.1 package must not require software
not present in Debian for execution.
https://www.debian.org/doc/debian-policy/ch-archive.html#s-main
Currently there is no OpenCL ICD for ppc64 in Debian - so I cannot
upload PyOpenCL for that architecture.
It would be much easier to just build PyOpenCL for all architectures,
but to be following Policy I need to manually maintain list of
architectures for which we have ICDs.
Best regards.

Quick update.
PyOpenCL from 2016-11-30 (commit
19015994653dffe2ee407271e19a46e1d6a62796) is in Debian testing,
for architectures amd64, arm64, armhf, i386, and amd64 and i386
for kFreeBSD. There is no release-critical errors against it
which means that this version of PyOpenCL should be in Debian Stretch.
As for PyCUDA, the version in Debian is from 2016-10-24,
commit 50457813cfe3eb359a230c4e1e546ccdef9947f8.
It's only available for amd64. I tried to build package
for ppc64el, but wasn't able to properly configure cross-compiler.
As Debian is in deep freeze now, I won't upload new versions
of packages Stretch release. Using this time I'll try to
make ppc64el PyCUDA - but it's not something I'll focus on entirely.
If you have questions or suggestions regarding packages,
please let me know.
Best regards.
