Installation failure

[Richard Gomes]

Hello,

I'm having trouble to install copperhead.
It's not finding boost-python library, despite I'm pretty sure I'm passing the correct arguments.



siteconf.py:

BOOST_INC_DIR = "/opt/cuda-dev/boost-1.48.0/include"
BOOST_LIB_DIR = "/opt/cuda-dev/boost-1.48.0/lib"
BOOST_PYTHON_LIBNAME = "boost_python"
CUDA_INC_DIR = "/usr/local/cuda/include"
CUDA_LIB_DIR = "/usr/local/cuda/lib"
NP_INC_DIR = "/usr/lib/python2.7/dist-packages/numpy/core/include"
TBB_INC_DIR = None
TBB_LIB_DIR = None
THRUST_DIR = "/usr/local/cuda/include/thrust/"



Python and boost-python

Could you please help me understand what I'm doing wrong?

Thanks

I've run into problems like this before due to stale SCons caches.  Can you try deleting your .scons_temp directory, the .sconsign.dblite database, and your config.log, and then rebuilding?  If that fails, please attach the config.log file that is produced by SCons.

Best,

bryan

Hello Bryan

Thanks a lot for your help.

On the spot, by the way.
I've deleted the directories you pointed out and it now works fine.

I just wanted to point out that configuration of THRUST_DIR is confusing.
I had to specify the directory which contains the "thrust" directory, not the "thrust" directory itself.
So, I had to enter

THRUST_DIR = "/opt/cuda-dev"

because I have actually thrust include files under directory /opt/cuda-dev/thrust/
This is my configuration, in case others find this thread useful:

BOOST_INC_DIR = "/opt/cuda-dev/boost-1.48.0/include"
BOOST_LIB_DIR = "/opt/cuda-dev/boost-1.48.0/lib"
BOOST_PYTHON_LIBNAME = "boost_python"
CUDA_INC_DIR = "/usr/local/cuda/include"
CUDA_LIB_DIR = "/usr/local/cuda/lib"
NP_INC_DIR = "/usr/lib/python2.7/dist-packages/numpy/core/include"
TBB_INC_DIR = None
TBB_LIB_DIR = None

THRUST_DIR = "/opt/cuda-dev"

I've also built Boost from sources into a separate directory (as can be seen from the configuration above) in order to avoid any sort of trouble in case system's Boost libraries change for whatever reason.

I believe that these points would be highly helpful in the installation instructions, including the trick related to SCons you mentioned.

Again, thanks a lot for your help and for Copperhead.

Cheers :)

Edit:

My architecture is AMD64.

It required a small change:

CUDA_LIB_DIR = "/usr/local/cuda/lib64"

... and a full recompilation:

$ rm -r -f .sconf_temp/ .sconsign.dblite config.log
$ python setup.py clean
$ python setup.py install

I've succesfully executed a couple of examples.

Thanks
