I install the library CUnit but I don't know how compile the program:

cunit.c:30:10: fatal error: CUnit/Basic.h: No such file or directory

The code you're tryhing to compile is not written correctly.  You'll
have to take this up with whoever wrote it.

In this particular line of code, my guess is the second == was supposed
to be = instead, to assign the result of fopen to the variable temp_file.

I have no idea what this code is even trying to do.  "Simulate a write
but without any actual data, just to make sure the file descriptor
still exists"?!  Why would that even be a thing?

Funny.

This, I cannot diagnose without digging through the whole source tree.

Remainder snipped.  The debian-user mailing list is not the place to
get help fixing a broken C or C++ program.  Please take it up with
the author or maintainer.
