Unfortunately, you are not asking how C++ (the topic of one of your
newsgroups) works.

You are asking how gcc works - how to compile a C program with it, how to
direct it to included files, etc.

You must ask this question on a single newsgroup or mailing list that covers
gcc, for the best results.

(You also should attend to any Makefile or "configure" files that may have
come with this source.)

Use http://www.google.com and http://groups.google.com to find the best
forum for this question.

void main(void)

I have ohter Makefile.


basically there is gcc test5.c test


since there is only one single test5.c. I think I should to ask expert to
help me out.

Stupidity will never get you very far.
Don't you even read the error messages?

Or is there something inherently difficult about
interpreting what "No such file or directory" means?

FWIW, this is a C++ newsgroup, not a C newsgroup. Of course your
problem has nothing to do with either C or C++...

gcc: test5: No such file or directory
test5.c:9:17: dos.h: No such file or directory

ISO C++ does not have a <dos.h> header, nor do most systems which are
not DOS (e.g., Red Hat).

The function outportb() is not part of C++. Rather, it's part of some
system-specific API. I'm guessing that this code was written to be
built under DOS, but you're now trying to build it under Red Hat. C++
cannot do what you need; you need to use Linux-specific functionality.
Consult a Linux newsgroup for more info on that.

test5.c: In function `main':
test5.c:21: warning: return type of `main' is not `int'

main() must have int as its return type, not void. (And in C, it must
also return a value, e.g., 0).
