[Gcl-devel] compiling gcl on Sharp Zaurus with gcc 2.95.3 and --enable-gmp=no

[Larry Clapp]

Greetings, all,

Today I tried my hand at configuring and compiling gcl on the Sharp
Zaurus, a Linux-based PDA.  I could only configure it if I said
"--enable-gmp=no", since the only gcc I have (at least, at the moment)
is 2.95.3.  GMP requires (at least) 2.95.4.

gcl won't compile with --enable-gmp=no, even on my Debian GNU/Linux
machine.  It crashes like so:

> % make
> (cd bin; make all)
> /big2/usr/src/gcl-2.5.3-arm/bin
> make[1]: Entering directory `/big2/usr/src/gcl-2.5.3-arm/bin'
> make[1]: Nothing to be done for `all'.
> make[1]: Leaving directory `/big2/usr/src/gcl-2.5.3-arm/bin'
> make mpfiles
> make[1]: Entering directory `/big2/usr/src/gcl-2.5.3-arm'
> make[1]: *** No rule to make target `mp/@MPI_FILE@', needed by `mpfiles'.  
> Stop.
> make[1]: Leaving directory `/big2/usr/src/gcl-2.5.3-arm'
> make: *** [unixport/saved_gcl] Error 2

So, thinks I, it would appear that the --enable-gmp=no doesn't fix the
makefile so as to not actually require gmp.  I commented out the "make
mpfiles" in the $(PORTDIR)/saved_gcl target, and got this:

> % make
> (cd bin; make all)
> /big2/usr/src/gcl-2.5.3-arm/bin

protoize.h, line 72, says

    extern object make_integer (__mpz_struct *u);

... except with --enable-gmp=no, main.c doesn't include whatever
defines __mpz_struct.

I tried commenting out the make_integer prototype, just to see what'd
happen (it seems ill advised; make_integer sounds like an important
operation), and it still crashes a bit further down the road.

Can anyone give me some hints on how to compile with --enable-gmp=no,
or should I rather try to get 2.95.4 compiled for that platform?

Or, if gcl requires gmp, why does it have an option to disable it?

Thanks for any help you can provide.
