matplotlib-devel Mailing List for matplotlib

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[@]}"
