Vector point/line profiling tool. See v.profile.html file for full description. v.profile requires GRASS 6.4 (r34499) or GRASS 7 (r34592 - not tested). To install v.profile, one needs to provide MODULE_TOPDIR variable for make command (MODULE_TOPDIR=/path/to/GRASS) or change MODULE_TOPDIR in supplied MAKE file to point to GRASS source base. If GRASS source is located in /home/user/soft/grass-6.4, then set MODULE_TOPDIR to /home/user/soft/grass-6.4. Before compiling this module, it's required to configure GRASS (it must have include/Make/Module.make file). Short version: svn co https://svn.osgeo.org/grass/grass-addons/vector/v.profile v.profile cd v.profile #nano Makefile # altrenative - edit MODULE_TOPDIR setting MODULE_TOPDIR='/path/to/grass-source' make make install
