[arch-general] C++ program compiliation failed

I have three c++ files: main.cpp, and querystring.{h,cpp}

querystring.h contains the definition for the QueryString class
and querystring.cpp contains the implementation.

querystring.cpp and main.cpp both have the statement #include "querystring.h"

Now when I run the compiler, I get a weird error-

$ g++ main.cpp querystring.cpp -o out
/tmp/ccxJ7C28.o: In function `main':
main.cpp:(.text+0x3e): undefined reference to `QueryString::QueryString()'
collect2: ld returned 1 exit status

How am I supposed to compile the program? i.e. in general a multifile
program having .hs and .cpps
