Hello there)
Currently I am experiencing some difficulties with compiling abinit 7.6 under raspberry pi (yep, i do understand that this task is practically useless).
The problem is that RPi has an ARM11 like cpu, which based on deprecated armv6 arch (v7 arch supported just great, no problem with ARM CortexA9 and so on).

Code: Select all

./configure yields following:
Summary of important options:

  * C compiler      : gnu version 4.6
  * Fortran compiler: gnu version 4.6
  * architecture    :   ( bits)

  * debugging       : basic
  * optimizations   : standard

  * OpenMP enabled  : no (collapse: ignored)
  * MPI    enabled  : no
  * MPI-IO enabled  : no
  * GPU    enabled  : no (flavor: none)

  * TRIO   flavor = none
  * TIMER  flavor = abinit (libs: ignored)
  * LINALG flavor = netlib-fallback (libs: ignored)
  * ALGO   flavor = none (libs: ignored)
  * FFT    flavor = none (libs: ignored)
  * MATH   flavor = none (libs: ignored)
  * DFT    flavor = none

So, it seams that linalg libs from tarballs are not usable. Open-BLAS could not be compilled from src for v6 arch.
What would you advise?

Hi,

LINALG flavor = netlib-fallback
...
So, it seams that linalg libs from tarballs are not usable.

why did you say that ?
the build system said that external linalg library is not available and therefore, it use the linalg library provided by abinit (= netlib and fallback)
PS : I have tested this, and it works...

but, on my raspberry under Debian 7, I have installed :

Code: Select all

apt-get install gfortran
apt-get install liblapack-dev

and I use this shell script to configure :

Code: Select all

#!/bin/bash
#
export CC=gcc
export CFLAGS="-O2"
export CXX=g++
export CXXFLAGS="-O2"
#
export F77=gofrtran
export FFLAGS="-O2 -g"
export FC=gfortran
export FCFLAGS="-O2 -g"
#
./configure \
     --with-trio-flavor=none \
     --with-dft-flavor=none \
     --with-linalg-flavor=netlib \
     --with-linalg-libs="-L/usr/lib -llapack -lblas"

but, due to a buggy version of gcc 4.6.3 under "Debian 4.6.3-14+rpi1" , you must also apply two patches on code :

1) in src/incs/abi_common.h

you can start the compilation with : make
now, you have time to drink 3 beers and eat two pizza :lol:

when, it finished, you can start some checks :

Code: Select all

root@pi:~/WorkSpace/abinit-7.6.2/tests# ./runtests.py fast

I succeeded also with the same recipe with a UDOO ( quad raspbery version : http://shop.udoo.org/eu/product/udoo-quad.html )

Yep, it seams i took too much beer that day) Moreover, in attempt to use OpenBlas - alternative linalg lib, I actually found a bug. It fixed now.

So, thanx, and best wishes!
