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?
Jason,
No, it is the name it gets when built under MSYS by default, nothing
cleverer than that, I'm afraid!
This is a different question entirely, but a heads-up might be worthwhile.
When R 2.11 arrives in three weeks time, there will be a 64-bit Windows
version. Because of the external dependencies on expat, proj4, and GDAL,
rgdal is one of only a very small group of CRAN packages that is not
available as a 64-bit Windows binary. It would be very useful if 64-bit
Windows users got together and figured out how to make a bundle of 64-bit
DLLs that could automate the CRAN Windows build of rgdal also for 64-bit
Windows. R is built with MinGW, so in the MSYS family. I have no access to
such a Windows platform, but have some advice from Brian Ripley, and one
interested helper. The more the merrier!
Roger
Thanks,
Jason

Yes, you are right. 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

/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.
Roger

Ivan

The root cause of the sourceforge issue is in a message posted
2010-03-25
from their admin:
"Update on the current CVS outage that is affecting projects whose UNIX
names start with the letters a, e, h, i, m, o, r, s, w, z.
The work being done on this server may take up to two days to resolve.
We?re
working to resolve this with alacrity and assure maximum stability and
performance."
So access should be back by the end of March.

Roger,
I in fact did my homework, but I've got a C.
As you can see on my previous message I did find the RGDAL Source

B+
at
least, no? If it worked.

That was a dead end.
Correct. When I tried, anonymous checkout from sourceforge was also
blocked - nothing we've done, maybe something sourceforge has done. I
have
changed the main description to:
"WARNING: rgdal is only available for download from CRAN - this
repository
is only used for development and browsing of source code. NEVER use the
very out of date file bundles for download from this site!!! See
http://rgdal.sourceforge.net for link."
Short of migrating to R-forge (which I have done for another R package,
spdep), there isn't much that can be done with sourceforge, I'm afraid
(sourceforge isn't my favorite place to be).
cc: Tim: Any idea why the anonymous checkout fails? Longer term - is
migration to SVN on R-Forge worth considering?
Roger
I download some of those zip packages from rgdal.sourceforge.net but
they
only have binary that requires FWTools installation.
Another dead end.
But you are right I should have search a little more to find the CRAN
page.
So I am downloading rgdal_0.6-2.5.zip now. Let's see how it goes.
That is the current Windows CRAN binary, get rgdal_0.6-25.tar.gz for
the
source. Install the Windows binary within R - do *not* treat the zip
archive as an archive - it is just a frozen binary version of the
source
for Windows.
Roger
Thanks you so very much Roger. Have a nice day.

Please, do your homework!
Google on "R rgdal" gives:
http://cran.r-project.org/web/packages/rgdal/index.html
http://rgdal.sourceforge.net/
where the latter says: "The R contributed package rgdal is available
from
CRAN", that is the first link. On CRAN you will find both the source
tarball
and a Windows 32-bit binary including 1.7.1 with standard drivers and
expat
for reading KML etc.
The sourceforge site is used exclusively as a CVS repository for
developers
- it hasn't been used for software distribution since about 2004; the
CRAN
distribution mechanism is far more robust and "just works".
Refer to show.file(system.file("README.windows", package="rgdal")) if
you
need to build from source for more exotic drivers.
The relevant mailing list is R-sig-geo,
https://www.stat.math.ethz.ch/mailman/listinfo/R-SIG-Geo/, and the
best
point of entrance, the R Spatial task view:
http://cran.r-project.org/web/views/Spatial.html.
Hope this helps,
Roger
