I added the few lines of code of G_alloc_matrix() inside my code, since otherwise it would indeed require the whole suite of advanced math libraries to be able to use it, and in this case I just needed a trusted Grass way to allocate to images in memory for a small module (gipe/i.eb.h_SEBAL01).
I would go to move those G_alloc_(i)(f)matrix() to libgis somewhere, as they dont particularly require anything to work. 2008/8/2 Glynn Clements <[EMAIL PROTECTED]>: > > Glynn Clements wrote: > >> > I am trying to keep temporary files in DCELL **G_alloc_matrix(nrows,ncols) >> > >> > on compilation I get an undefined reference to that function... >> > >> > Checked in gis.h it is referring to gisdefs.h which has the definition. >> > I just svn up on trunk with full distclean and full recompile, still same. >> >> Contrary to what you would naturally assume from the headers, >> G_alloc_matrix() is actually in the gmath library, so you need to add >> $(GMATHLIB) to LIBES. > > I'm wondering whether those functions (matrix/vector alloc/free) > really belong in the gmath library.
