Computer Stuff

I was trying to compile a C++ program:

gcc a.cpp

Got this:

Undefined first referenced
symbol in file
cerr /var/tmp/ccKpgRuk.o
cout /var/tmp/ccKpgRuk.o
string_char_traits::move(char *, char const *, unsigned int)/var/tmp/ccKpgRuk.o
endl(ostream &) /var/tmp/ccKpgRuk.o
__out_of_range(char const *) /var/tmp/ccKpgRuk.o
ostream::operator<<(ostream &(*)(ostream &))/var/tmp/ccKpgRuk.o
ostream::write(char const *, int) /var/tmp/ccKpgRuk.o
string_char_traits::length(char const *)/var/tmp/ccKpgRuk.o
__length_error(char const *) /var/tmp/ccKpgRuk.o
string_char_traits::copy(char *, char const *, unsigned int)/var/tmp/ccKpgRuk.o
ostream::operator<<(char const *) /var/tmp/ccKpgRuk.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status

This is caused by not linking to the C++ library,

gcc -lstdc++ a.cpp

would fix it.
