This means one of two things happened:
a) you used pkunzip and streambuf.h got truncated to streambu.h (hence gxx
couldn't find it). Use Winzip to preserve long filenames. Solution? Try
reinstalling DJGPP only using WinZIP this time. But if you did that...
b) LFN is turned off in your DJGPP distribution. The latest version comes with
it enabled, older ones (maybe the one on the CD) may have it disabled. To find
out which version you've got, type gcc --version at the DOS prompt. If it's less
than 2.81, you might have to do the following:
Go to your DJGPP base directory (like C:\djgpp for example). Edit djgpp.env.
You'll see a line close to the beginning of the file like this:
+LFN=x
Where x is either y or n. Make sure it's y. You definitely want that enabled.
Save your change, then try compiling again, and see what happens.
It should work.

Oh wait, I'm guessing a) is not the case, if you copied it right off the CD.
Then do what I suggest in b).
