Thread: [matplotlib-devel] installation on AIX with XLC compiler

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi,
the more recent information on installing matplotlib on AIX with XLC 
compiler are pretty dated (5 years ago), so I'd like to let you know 
what I did to have it on my machine. This is matplotlib-v1.1.0 on 
AIX-v5.3 and xlc-v10.1

Some code is worth 1000 words, so here it is, just a couple of comments:

- Note that similar problems occurred when installing scipy: 
http://projects.scipy.org/scipy/ticket/1299

- if I understand C++ Standard (ISO/IEC 14882), section 14.6.4.2, you 
should apply my patch1 below to the mainline (trunk).

#!/bin/bash

cat >xlC <<-"xlC-script-fooling"
      #!/bin/bash
      echo "Davide's xlC - parameters:" $*
      tbr=""

       # getting rid of wrong cc_r first argument
       # note that $1 becomes $params[0]
       [ "$1" = "cc_r" ] && tbr=0

       # getting rid of other unwanted arguments
       params=( "$@" );

       for i in ${!params[*]}; do
             # you don't link to stdc++ with XL compilers
             [ "${params[$i]}" == "-lstdc++" ] && tbr="$tbr $i"
       done

       for i in $tbr; do
             unset params[$i]
       done

       # -qmkshrobj is to create shared objects with XLC
       set -- "-qmkshrobj ${params[@]}"
