libgis (and thus all of GRASS) requires zlib. If you use --without-opengl, --without-x11, --without-wxwidgets and --without-tcltk, that eliminates a lot of dependencies at the expense of NVIZ, vdigit, xganim, and ximgview. For the GUI, wxPython will need some of those libraries, but you aren't hard-coding dependencies on specific versions into the package. If you still want NVIZ, building --without-ffmpeg may significantly reduce the number of dependencies. Building --without-cairo gets rid of a few more, as does --without-blas/lapack and --without-fftw (both of these add dependencies to the gmath library, which is used by ~34 modules). The PNG driver can be built --without-png; the GUI only needs PNM output, which doesn't require any libraries. Once you've done all of that, you're left with PROJ, GDAL, and whatever libraries GDAL requires. The main issue is that GDAL can require an almost open-ended set of libraries, depending upon which options it was built with. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
