problem in C++

I tried to include some assembly code into C++ but I didn't worked.
In Windows all is just fine but with this code in test.cpp:

#include <iostream>

using namespace std;

int main()
{
char *a="this is a message";
int len=strlen(a);
_asm{
//some assembly code
}
return 0;
}

when "g++ -o test test.cpp" I receive an error telling me he doesn't know what "_asm" is.
Could someone tell me how could I correct this?

Thanks!

If I'm not mistaken, _asm is a VC++ macro so g++ has no idea what you're talking about. To do this, just put the asm code in a .asm file, use nasm to assemble the code to a .o file and then use g++ -c to compile your c++ code and then use g++ -o outfile obj1.o obj2.o asmbleycode.o cpluspluscode.o main.o (etc...whatever, howevery many files you have) to make the final executable binary
