Some users have reported problems with the CD that comes with that
book.  Those problems may now be fixed, but you should consider
downloading the latest version of DJGPP from http://www.delorie.com

You need to run a dos box under Windows.  Look for the shortcut on the
start menu to MS-DOS Prompt and use that.

Notepad is ok for emergencies but you will soon be tired of it, and it
has the problem of saving the file as hello.cpp.txt if you are not
careful.  Download RHIDE or do a web search for a programmers editor.

Type all the commands in the DOS box:

c:
cd \
gxx -Wall hello.cpp -o hello

GCC produces .o files, but the above command compiles and links in one
go so there is no intermediate object file.

Check that hello.cpp does actually exist.  Use the dir command for
this because Windows Explorer can hide file extensions and does not
always show filenames with the correct case.

Hope that helps,

Jason.
