compilation terminated."

please help me is there any lib file is missing or any other

thanks in advance
Working as root?

iostream.h is deprecated. It's part of the old I/O Stream library and was replaced by the C++98 standard.

The replacement is
#include <iostream> 
thanks for the response. initially i got an error as

../../include/../base_class/ error: ‘memcpy’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]
In file included from /usr/include/string.h:642:0,

from ../../include/../base_class/,
/usr/include/i386-linux-gnu/bits/string3.h:49:1: note: ‘void* memcpy(void*, const void*, size_t)’ declared here, later in the translation unit
make[2]: *** [matrix_i_t.o] Error 1
make[1]: *** [inst_tmpl] Error 2
make: *** [base_class] Error 2

please help me
Include <cstring> before using memcpy.
