Pascal Dupuis - 2012-01-23

Hello,
I would like to give MathGL 2.0 a try. Under Fedora 16, I installed all the
required the -devel packages. mathgl compiles with a few warning, but then
installing the octave package fails with
failed to load: /$HOME/octave/mathgl-2.0.0/i386-redhat-linux-gnu-
api-v45+/mathgl.oct: undefined symbol: mgl_data_data_
a 'nm -C' on mathgl.oct shows this file contains the undefined symbol
mgl_data_data_, which is mentioned in include/mgl/data.h, but no
implementation is found in mgl.so. Any idea ?

Also, if I use mkoctfile to generate the .oct package, I have different
undefined symbols ???

TIA

Pascal

Thank you, it is my error -- I declare this function in header file, but
forgot to implement. I fix this bug in SVN version. However, swig shouldn't
use these (C-only) functions by default. Can you send me the list of undefined
symbols and commands which you are using for generating *.oct?
