Roger, Pardon me for interrupting with a question I've had for a while but not asked you.
On Windows at least, it appears that rgdal renames the GDAL shared library (e.g. gdal16.dll) to an rgdal-specific name (e.g. libgdal-1.dll). On windows, this has the advantage of avoiding DLL name collisions, allowing rgdal to coexist with other libraries that also load GDAL using its traditional name (e.g. gdal16.dll). Is that why rgdal renamed the shared library? Or was it done for another reason?

The source code is on rgdal_0.6-25.tar.gz, I know, but the instructions to build on Windows are on the rgdal_0.6-25.zip package on README.windows, where it says: > > --- > The R Windows binary rgdal package is built against an FWTools Windows binary, using VC++. > > Notes: > > Building rgdal.dll in rgdal/src: > > cl /MT /Ox /EHsc /D "WIN32" /c /I E:\rsb\R\R-2.2.1pat\include /I C:\Programfiler\FWTools1.0.0a7\incl > ude *.cpp > > link /dll /out:rgdal.dll /def:RGDAL.def gdal-bindings.obj ogr_geom.obj ogr_proj.obj ogrsource.obj E: > \rsb\R\R-2.2.1pat\lib\Rdll.lib /libpath:"C:\Programfiler\FWTools1.0.0a7\lib" gdal_i.lib > --- > > So I am trying to change it a little bit in order to build against GDAL 1.7.1 (or trunk). > > How does that sounds to you? Good idea? Ivan, No, the README.windows file is of course in the source tarball, in the inst directory (as usual for R packages). If you install the Windows binary, you'll see that it includes GDAL 1.7.1, that is the message reporting the GDAL runtime version shown when the package is loaded. The only reason for doing anything at all is if you need drivers not already provided for your own purposes. Then you might need to review the README.windows file and, for example, build against current FWTools or OSGEO4W distributions. Please do check the drivers first with ogrDrivers() and gdalDrivers() in R after loading the package.
