GMP ready and packaged.
Compiled with "-O2 -g -fomit-frame-pointer -march=i486 -mcpu=i686"
Shared library *only* (it *either* support static *xor* shared... I
opted for the latter)
Fine decision, IMO.
As usual the source package contains my cryptographic signature on patch
and script and original package signature on original package.

sdesc: "GMP is a free library for arbitrary precision arithmetic"
ldesc: "GMP is a free library for arbitrary precision arithmetic,
operating on signed integers, rational numbers, and floating point
numbers. There is no practical limit to the precision except the ones
implied by the available memory in the machine GMP runs on. GMP has a
rich set of functions, and the functions have a regular interface."
category: Math Libs
requires: cygwin
1. I'd prefer if the sdesc were a little more specific: it's a GPL
library (e.g. free as in speech), not BSD or LGPL (free as in beer).
2. As far as the source packaging goes, it looks fine to me (built
okay). You probably want to fix this:
configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.
3. I guess from cgf, this is okay:
-march=i486 -mcpu=i686
which translates to 'use 486 instruction set, but tune for optimum
performance on 686'
4. It looks like the binary is compiled for cygwin-1.5.3+ -- or at
least, the README implies that.
5. Didn't ssh at one time or other require gmp? Could cygwin's ssh
distro benefit from this package -- or was that the non-free ssh?
6. Are you sure about the requires? I got a dependency on
cygreadline5.dll -- for the demo programs which you don't ship...Might
it be a good idea to ship some of those? (course, you have to install
by hand -- and note rename of calc.exe)
cd <builddir>/demos
make factorize.exe isprime.exe pexpr.exe primes.exe qcn.exe
/bin/sh ../libtool --mode=install install -s -m 755 \
factorize ${instdir}${prefix}/bin/
/bin/sh ../libtool --mode=install install -s -m 755 \
isprime ${instdir}${prefix}/bin/
/bin/sh ../libtool --mode=install install -s -m 755 \
pexpr ${instdir}${prefix}/bin/
/bin/sh ../libtool --mode=install install -s -m 755 \
primes ${instdir}${prefix}/bin/
/bin/sh ../libtool --mode=install install -s -m 755 \
qcn ${instdir}${prefix}/bin/
cd <builddir>/demos/calc
make calc.exe
/bin/sh ../../libtool --mode=install install -s -m 755 \
calc /desktop/foo-test/gmp-4.1.2/.inst/usr/bin/gmp-calc
7. Also, the README doesn't mention the following build-requires:
bison
flex
m4
(gcc, binutils, of course)
8. Any thoughts on --enable-cxx ? --enable-mpfr ?
9. GMP uses very old-school libtool-1.4. I know it *works* -- but have
you considered following the instructions in doc/configuration to update
to the newer autotools ?
10. Finally, you might think about splitting this into multiple packages
-- it's better to do so at first, than go thru the "split hell" later.
Unless you're pretty sure there will never be a cyggmp-4.dll.
I'd suggest:
libgmp3 - contains cyggmp-3.dll
libgmp-devel - contains import, libtool lib, includes
perhaps named gmp-devel, instead
gmp - everything else: docs, info, demo progs, etc
11. (I lied) /usr/info/dir is in the package. It shouldn't be. See
next message.
