trouble linking INTEL tbb library

Question

I read these threads:

Getting Thread Building Blocks (Intel TBB) running on Linux with gcc

unable to link Intel TBB library with libtbb in /usr/lib

g++ can't find headers even when it's specified

g++ cannot find header file

g++ can't find headers but I did include them

but still get this error:

   piCalc.cpp:8:17: fatal error: ttb.h: No such file or directory
 #include "ttb.h"

My code to calculate pi starts with

#include <iostream>
#include "ttb.h"
#include "parallel_for.h"

Running Ubuntu 14.04 with nvidia and cuda installed. To install TBB, I started with :

sudo apt-get install libtbb-dev

and it said

Reading package lists... Done
Building dependency tree       
Reading state information... Done
libtbb-dev is already the newest version.
The following package was automatically installed and is no longer required:
  libxine2-bin
Use 'apt-get autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So I thought I was good to go. So, I tried:

g++ piCalc.cpp -ltbb -o pi 

and get the error. So I downloaded the archive from intel and decompressed it to my home directory into a directory named tbb.

Issuing ls gives:

CHANGES  COPYING  README  bin  doc  examples  include  index.html  lib  piCalc.cpp

Notice piCalc.cpp is in the tbb directory. Also, tbb.h is located at /include/tbb So I changed the include statements to

#include <iostream>
#include "/include/tbb/ttb.h"
#include "/include/tbb/parallel_for.h"

libtbb.so and libtbb.so.2 are located at lib/intel64/gcc4.4

My terminal command was issued thusly:

g++ piCalc.cpp  -o pi -I include/tbb -L lib/intel64/gcc4.4 -ltbb

as well as

g++ piCalc.cpp  -o pi -I include/tbb/ -L lib/intel64/gcc4.4/ -ltbb

as well as

g++ piCalc.cpp  -o pi -I /include/tbb -L /lib/intel64/gcc4.4 -ltbb

and the same error occurs

piCalc.cpp:8:30: fatal error: /include/tbb/ttb.h: No such file or directory
 #include "/include/tbb/ttb.h"

I tried absolute paths with this:

g++ piCalc.cpp -I /home/stefan/tbb/include/tbb -L /home/stefan/tbb/lib/intel64/gcc4.4 -ltbb -o pi

Still same error.

I tried changing my code to:

#include <iostream>
#include </home/stefan/tbb/include/tbb/ttb.h>
#include </home/stefan/tbb/include/tbb/parallel_for.h>

and get this:

stefan@HN5:~/tbb$ g++ piCalc3.cpp -I /home/stefan/tbb/include/tbb -L /home/stefan/tbb/lib/intel64/gcc4.4 -ltbb -o pi
piCalc3.cpp:8:46: fatal error: /home/stefan/tbb/include/tbb/ttb.h: No such file or directory
 #include </home/stefan/tbb/include/tbb/ttb.h>
                                              ^
compilation terminated.

Basically the same error but more verbose since I used the absolute path in the terminal command.

I thought maybe the LD_LIBRARY_PATH variable was important. CUDA messes with the LD_LIBRARY_PATH variable so I exported the intel libs and now printenv shows:

LD_LIBRARY_PATH=/home/stefan/tbb/lib/intel64/gcc4.4:/usr/local/cuda-7.5/lib64:

still getting the error.

Here is the verbose error:

stefan@HN5:~/tbb$ g++ piCalc.cpp -o pi -v -I/home/stefan/tbb/include/tbb -L/home/stefan/tbb/lib/intel64/gcc4.4 -ltbb

I also get this error if I copy the include/tbb folder which has all the .h files into the /usr/local/include folder. I also tried brackets instead of quote for the include files in the source.

Since my brain is in a deep rut by now, I am hoping someone can help me by pointing out what I am missing.

Answer 1

FINALLY, I figured it out so I am posting here so anyone else might benefit.

1. Download the Intel libraries from here
2. Extract the folder and rename it to tbb
3. Move that folder into /usr/local
4. In source use: #include <tbb/tbb.h>
5. g++ test.cpp -o program -ltbb
