Thanks for the note.  It seems that "make" on your system didn't
expand the "$PWD" (current directory) variable.

This should be moot, since the game will eventually be set up with
autoconf/automake, and there'll be a "make install" step, which will
copy all of the data to somewhere like "/usr/local/..." or "/usr/share/..."

All of the complaints you see are pretty standard.

I want the main 'tuxmath' directory to remain fairly clean even after
you build (with "make"), so I stored all of the source files in "src/"
and have all of the object (".o") files get built into an "obj/"
directory.

Some versions of tar, however, don't 'mkdir' directorys which, in the
tar archive, are empty.  So, I make sure that "obj" is 'mkdir'd every
step of the way, hence the constant "cannot make directory `obj'" warnings.
(Notice they are ignored :) )

There are also many warnings (thanks to "-Wall" switch to 'gcc') about
things being "defined, but not used" in ".h" files.  These are definitions
of string constants which are used in the accompanying ".c" files, but
not at all in the ".h" files, which GCC is complaining about.

I'm not really all that good at writing C programs that aren't all in
on gigantic C file (see my numerous other games :) ), so I don't know the
best way to rid this warning.

Tips?

Anyway, other than these warnings and errors (which I get too ;) ),
and the odd lack of "$PWD" variable in "make", it sounds like it built
and ran for you, which is good! :)

Out of curioisity, what model and version of 'make' are you running?
(Is it "gmake", or?)

And what OS/architecture?  (Sounds like probably RedHat on Intel?)

Thanks!!!
