[GRASS-dev] Integrate XDR lib into GRASS?
Hi, here at the FOSSGIS.de conference we tried to compile GRASS for Android. A major obstacle was XDR (e.g., https://svn.r-project.org/R/trunk/src/extra/xdr).

Maybe it would be overkill, but gnulib is designed for such portability issues, maybe grass could use that more generally? http://www.gnu.org/software/gnulib/ I checked that there is some xdr support (from glibc): http://www.gnu.org/software/gnulib/manual/html_node/Glibc-rpc_002fxdr_002eh.html#Glibc-rpc_002fxdr_002eh There is an entry cost, though, and it integrates better when automake is used too.

Unfortunately it will not help: http://www.gnu.org/software/gnulib/manual/html_node/xdrmem_005fcreate.html#xdrmem_005fcreate - Portability problems not fixed by Gnulib: This function is missing on some platforms: Cygwin 1.7.4, mingw, BeOS. ... and MingW is one of the relevant platforms... Indeed, it seems in fact that none of xdr* are really implemented, so that the platforms where the function is missing are merely listed... But if R and grass both need it, that's a hint that it may make sense to add them, even though you don't end up using it! I'll certainly go ask on the gnulib mailing list whether there is specific issue with xdr and gauge the interest there. -- Pat ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
