Where is arrayfire/lib64 and libafcu?

Question

After I build and install arrayfire, and I read the complete documentation in http://www.arrayfire.com/docs/createprojects.htm#createprojects_linux, bur I could not find the arrayfire/lib64 in my computer, so how to set up Environment Variable AF_PATH?

export AF_PATH=/home/arrayfire
export LD_LIBRARY_PATH=$AF_PATH/lib64/:$LD_LIBRARY_PATH

And I also didn't find libafcu.so, so there is problem when add the flags described in the hyperlink above:

 g++ *.cpp -lafcu

I wonder if there is any thing I have misunderstand? This is my first time trying to programe in linux.

Thank you

Answer 1

I couldn't get the examples to compile because of the same issue you mentioned. Instead of -lafcu, link against libafcuda.so by using -lafcuda. It seems that the latest commit in the master branch has changes a few things here and there.

If you do make install after the compilation, the dynamic library files will be copied in /usr/local/lib (under Ubuntu 14.04) (you'll have libafcpu.so and libafcuda.so). Thus, set your LD_LIBRARY_PATH accordingly.

Answer 2

Just replace -lafcu with -lafcuda and there is no directory $AF_PATH/lib64 anymore, but when change the library directory to $AF_PATH/lib, the problem could be solved.
