the error i get is this

collect2: ld returned 1 exit status

Answer 1

You are compiling a .cpp file with gcc. Rename the file to end with .c so it compiles as C code or compile it with the C++ driver g++. That will link in the stdc++ library providing these functions.

Answer 2

ld is the linker and it is reporting that there is a link problem. The gxx part of the error message hints that it has something to do with a C++ problem which makes the answer Johannes Schaub - litb gives about the root cause correct.
