Re: Problems in installing Octave General package

[Guido Walter Pettinari]

Hi Carlo,

thank you for your help. I managed to install the package by following  
the indications found in http://www.supermegaultragroovy.com/blog/2009/09/17/installing-octave-packages-in-snow-leopard/ 
. The solution is to add the following snippet

CFLAGS="-m32 ${CFLAGS}"
FFLAGS="-m32 ${FFLAGS}"
CPPFLAGS="-m32 ${CPPFLAGS}"
CXXFLAGS="-m32 ${CXXFLAGS}"
LDFLAGS="-m32 ${LDFLAGS}"

in the file Octave.app/Contents/Resources/bin/mkoctfile-3.2.3 just  
after the "set -e" line. The problem was that in Snow Leopard  
compilers try always to build in 64bit, while libraries shipped with  
Octave are 32 bit. The -m32 flag forces the compiler to build 32bit  
programs.

Cheers,

Guido
