Package: pari
Version: 2.5.0
Hello Bill,
I have had a chance to do some more research into the environment on the
HPux rx4640 Itanium /HPux 11iv3 platofrm in which I am trying to install
pari 2.5.0.
The gmplib.org documentation site in the section
http://gmplib.org/manual/ABI-and-ISA.html#ABI-and-ISA for IA-64 shows
two possibilities: IA-64 under HP-UX and other IA-64 systems, basically
Linux implementations.
The HP-UX specifics show that GMP can have either
an ABI=32 environment where pointers, ints and longs are 32 bits and GMP
uses a 64 bit long long for a limb or
an ABI=64 environment where pointers and longs are 32 bits and GMP uses
a long for a limb.
The initial GMP statement showing 2 possible HP-UX ABI environments says
that peformance is the same in both.
When I built the gcc 4.5.3 environment at our site, I did not specify a
special ABI for GMP, mpfr, mpc, etc when building them so that their ABIs
are the default ABI=32.
In the PARI GP version 2.5.0 config/ directory there is a program
gmp_version.c
#include <stdio.h>
#include <gmp.h>
void f(void) { mpn_gcdext(NULL,NULL, NULL, NULL, 0, NULL, 0); }
main()
{
if (sizeof(mp_limb_t) == sizeof(long))
printf("%s", gmp_version);
else
printf("unsupported");
}
The code will not return a gmp_version for the HP-UX / GMP ABI=32
environment where sizeof(mp_limb_t) would need to match sizeof(long long).
The code will return a gmp_version for the Linux environments where longs
are 64 bits.
If the gmp_version.c code is modified to
#include <stdio.h>
#include <gmp.h>
void f(void) { mpn_gcdext(NULL,NULL, NULL, NULL, 0, NULL, 0); }
main()
{
if (sizeof(mp_limb_t) == sizeof(long long))
printf("%s", gmp_version);
else
printf("unsupported");
}
the ./Configure process returns
...
Given the previous choices, sizeof(long) is 4 chars.
The internal word representation of a double is l[0], l[1].

Building for: Itanium running hpux (portable C/GMP kernel) 32-bit version

...
Checking for optional libraries and headers...
...Found libgmp in /usr/local/GNU/lib
...Found gmp header in /usr/local/GNU/include
Using GNU MP, version 5.0.2
...
which would seem to be correct for our site. I realize that just
bending the ./Configure process to pass for our site's GMP environment
doesn't mean that doing that won't introduce other problems during the
build and use of pari later on. I will try a build and check to see what
the consequences are. Perhaps a more elegant patch could be put into
gmp_version.c (and pari, if necessary) to accomodate the HP-UX / GMP
peculiarity for IA-64 platforms. My other alternative is to build a
separate environment for ABI=64 GMP and its associated libraries so that
it functions essentially like the Linux IA-64 environments. Since I
currently don't need a separate ABI=64 GMP environment for anything else
besides pari, I guess I would prefer that pari change, if possible.
The build, /usr/local/bin/gmake gp, of pari 2.5.0 on HP-UX 11iv3 with
the change to gmp_version.c does fail with the following:
...
gcc -c -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer -I. -I../src/head
ers -fPIC -o hash.o ../src/language/hash.c
../src/language/hash.c:171:1: error: conflicting types for 'compound'
/usr/include/math.h:379:23: note: previous declaration of 'compound' was here
gmake[1]: *** [hash.o] Error 1
gmake[1]: Leaving directory `/DreamLand/JunqueYard_gccN/pari-2.5.0/Ohpux-ia64'
gmake: *** [gp] Error 2
Thanks for your assistance
Bill
