Dear all

I am a Mac user.  When I upgraded to Mac OS 11 BigSur, I started having
problems with �rgdal� and �sf�.

I managed to get "sf" to run on MacOS 11.0.1 by recompiling most of the
required packages. Here's the recipe:

1. Remove all spatial software from brew (if you installed it). Rgdal does
    not like "brewed" stuff (I believe Roger prefers wine). Seriously, it
    appears that rgdal looks for libraries in their default places and not
    in the "Cellar" libraries used by "brew".

2. Install Xcode 12.3beta (downloaded from Apple Developers). This is the
    latest version of XCode which is compatible with MacOS BigSur.

3. Install "wget" using brew:

"brew install wget".

4. Download the libraries below from their sources:

(a) sqlite-autoconf-3330000.tar.gz from "https://www.sqlite.org/download.html".
(b) tiff-4.1.0.tar.gz from "https://download.osgeo.org/libtiff/"
(c) proj-7.2.0.tar.gz from "https://proj.org/download.html#current-release"
(d) libgeotiff-1.6.0.tar.gz from "https://download.osgeo.org/geotiff/libgeotiff/"
(e) geos-3.8.1.tar.bz2 from "https://trac.osgeo.org/geos"
(f) gdal-3.2.0.tar.gz from "https://gdal.org/download.html"

5. In the order given above, unpack each library and then execute the
    following commands:
% ./configure
% make
% sudo make install

6. Now you are ready to compile "rgdal" and "sf" from source. Using the R
    console,do:

> install.packages("rgdal", type = "source�)
> install.packages("sf", type = "source")

7. After those steps, both "rgdal" and "sf" are working on MacOS BigSur.

Hope this helps Mac users.

Best
Gilberto
