Fun with Intel TBB!

Phew! With Linux there's always some amount of configuration/tweaking reqd. before you can build source or make use of a new library...And I must tell you, I luv this challenge! The best example of this is when you want a GNU app or a framework to help you do something more with your Linux box. Most of the time we'll download src code from GNU free s/w websites like sourceforge etc to get started. And then starts the process to configure, make the src and install it. That's not all, sometimes you've to go a step further and comment or fix some simple errors (like casting) in the C files of the app before you can successfully build the app and get the reqd. binaries.
Here I want to capture an experience I had with installing TBB on my Linux box (running SLES 10 with 2.6.16.21 kernel and gcc/++ version 4.1.0)
Let's go step-by-step from here:
1) copy the following tar.gz files to some folder like /tbb/
tbb20_20070927oss_src.tar.gz
tbb20_20070927oss_lin.tar.gz
2) Now, extract everything there itself using tar -zxvf filenames
3) This will give you two folders:
tbb20_20070927oss_src
tbb20_20070927oss_lin
4) From tbb20_20070927oss_lin copy the folder ia32 to tbb20_20070927oss_src directory (it's a 32 bit platform on an intel box)
5) If you're lucky enuf you'll get the libtbb.so and others for your kernel+glibc version in one of the four folders inside: tbb20_20070927oss_src/ia32
6) If not, we need to build the libtbb.so (the crux of everything) for your platform, so "cd /tbb/tbb20_20070927oss_src/src/tbb/"
7) Run "make" here and see if your luck strikes, to get a libtbb.so w/o errors.
8) If not, then try either of these things or both:
(a) If you see a make Error for task.cpp then you may be asked to fix this:
/src/tbb/task.cpp:396: warning: deprecated conversion from string constant
I know you can do this, so I won't fix it for you here ;)
(b) If it still doesn't work then figure out what else is preventing a successful make of libtbb.so and try resolve it.
Lastly, you can try using the libtbb.so from any of the ia32 folders like: tbb/tbb20_20070927oss_src/ia32/cc4.1.0_libc2.4_kernel2.6.16.21/lib
9) Once you've the right version of libtbb.so and libtbbmalloc.so for your platform, create their soft links in /usr/lib/
10) Now, we're ready to make a sample code supplied with TBB src.
Goto sample code folder "cd tbb/tbb20_20070927oss_src/examples/parallel_for/seismic" and do a make here.
11) Again, things are not that straight buddy!
You need to either add to Makefile the include path for files included in Seismic.cpp like /tbb/tbb20_20070927oss_src/include/tbb/parallel_for.h or edit the .cpp file to have absolute path to these .h files
12) After fixing all these make dependencies, you'll be able to build the binary and see it running on your Linux machine with figures telling you no. of fps with parallelism.

Now that we've the machine run this example successfully, why not try our own parallel_for which seems to be a good starting point to go parallel the Intel way!!
