[GRASS-user] libgrass_gmath

    Despite (or perhaps because of) downloading and installing new 
wxPython, gdal, fftw, and others I have forgotten, compiling 
grass7_trunk generated numerous errors.  libgrass_gmath.7.0.svn.so 
compiled successfully, but then whether I set --with-fftw or 
--without=fftw libgrass_gnath generated numerous errors related to 
missing references in fftw.  E.g. in r.gwflow

/libgrass_gmath.7.0.svn.so: undefined reference to `fftw_execute'
/libgrass_gmath.7.0.svn.so: undefined reference to `fftw_plan_dft_2d'
/libgrass_gmath.7.0.svn.so: undefined reference to `fftw_destroy_plan'

   I noticed that the routines generating the errors are routines I 
don't call, so despite the errors I tried make install and it worked!
However, I still have the problem that v.dissolve doesn't work.

Oh well, at least I can get back to work, Dave
