Any pointers in the right direction would be appreciated.

Well, this is the Intel C++ Compiler forum, and your question seems to be how do you get lambda's working. It seems to work fine with the switch mentioned in the other thread, "-std=c++0x":

[cpp]$ icc -c lambda1.cpp 
lambda1.cpp(43): error: expected an expression
  [&](){ par_ms(beg, mid, A); }, 
  ^

lambda1.cpp(44): error: expected an expression
  [&](){ par_ms(mid, end, A); } 
  ^

compilation aborted for lambda1.cpp (code 2)
$ icc -std=c++0x -c lambda1.cpp 
$ 
[/cpp]

That was with the 11.1 compiler.

I agree that it will work with the Intel compiler. I'm working with gcc.
A person who replied to the other thread said that lambda's will be supported only from gcc 4.5 onward (which isn't available for download as yet).
Is that true?

It's true. The replies in this thread say so: http://software.intel.com/en-us/forums/showthread.php?t=71088page/1/#106781

I don't know where you're going with it, but gcc 4.5 source and pre-built versions are available. It's a pre-release; I think gcc-4.4.3 is the most recent release. For example, gfortran wiki has gfortran and g++ builds for several of the usual platforms.

Could you point me to any links where I could download it from?
