mpir on 32-bit

[kcrisman]

See http://ask.sagemath.org/question/1713/error-installing-package-mpir-240p6

Will this probably need an spkg upgrade to fix?  It's nice that people are finding the answer on ask.sagemath, but...

We are now at MPIR 2.6.0, so it would be nice to know if this upgrade alone fixes the problem.

I have problems in compiling sage 5.7. The build stops during the build
of the mpir-2.6.0.p0 package.

spkg/logs/mpir-2.6.0.p0.log is pasted at http://paste.debian.net/237529/

The problem seems related to some 32bit architecture (hence i send my
message on this thread) :

Building a 32-bit version of MPIR.
Building MPIR with the C++ interface and (also) static libraries.
** Building with "fat binary" support for 32-bit CPUs **
[...]
configure: error: ABI=32 is not among the following valid choices: standard
Error configuring MPIR (with CFLAGS unset).

The machine is running Debian wheezy,
Linux 3.2.0-4-686-pae #1 SMP Debian 3.2.35-2 i686 GNU/Linux

I used the following sage variables :
- SAGE_FAT_BINARY='yes'
- SAGE_BINARY_BUILD='yes'
- SAGE_CHECK="yes"
- MAKE="make -j2"

I had no problem building 5.6 on the same machine with the same
configuration. I will try to 'export ABI=standard' as suggested in
ask.sagemath.

Ciao,
Thierry

Exporting ABI='standard' globally allows the mpir spkg to be built but
then gap-4.5.7.p3 cannot be built since it also uses the ABI variable
for which the value 'standard' does not make sense (it only accepts
ABI=32 or ABI=64).

I created a ticket at http://trac.sagemath.org/sage_trac/ticket/14172

Ciao,

Ill report this on mpir group.

That included MPIR 2.4.0.

This seems to be an upstream bug (actually, a regression) in MPIR 2.6.0,
which apparently doesn't allow ABI=32 specifically on
core[-pc-linux-gnu] (i.e., on old Intel Core CPUs, predecessors of the
Core2 processors).

(Setting ABI=standard [only] when installing the MPIR spkg is just a
work-around.)
