OSX, rgdal, GDAL drivers and HDF4

Hello,

This is my attempt to look before I leap into installing GDAL on OSX. (You can probably hear my pitiful groaning and knee-knocking in the background.)

I want to read many HDF4 files for which I do not have the GDAL HDF4 driver installed.  I used William Kyngesburye's nice framework (http://www.kyngchaos.com/software:frameworks) to install GDAL but it came without the HDF4 driver.

Reading this somewhat dated exchange... 

http://r-sig-geo.2731867.n2.nabble.com/Read-HDF-files-td6750856.html

... I think I understand that if I want the HDF4 driver I must build GDAL on my system manually.  Is my understanding correct, or is there another (easier) way to read HDF4 files directly in R?

Thanks!
Ben

Have you tried with the homebrew project? HDF4 isn?t a default supported
driver, but it?s easy enough to add:

 brew install hdf4
 # prefer hdf4 links over NetCDF
 brew link --overwrite hdf4
 brew install gdal --complete --enable-unsupported --with-hdf4

 # check what drivers are installed, list should include ?hdf4?:
 gdal-config --formats

I?d use that as a starting point.

Cheers,
Shaun
