How to include <algorithm> header of stl in gcc?

[Pritam Gharat]

Hi,

    I am using sets of stl in gcc. I need to perform operations like set 
union, set intersection and set difference for my analysis. These 
functions are defined in the header <algorithm>. However, when I include 
this header in my file, I get the following error:

/home/pritam/GCC_BUILDS/gcc_4.7/install/lib/gcc/i686-pc-linux-gnu/4.7.2/../../../../include/c++/4.7.2/cstdlib:76:8:

make: *** [pointsto-callstrings.o] Error 1


How can I resolve this problem?
