Building GDAL on Linux

16-Jan-2011

Latest gdal on Ubuntu is 1.7.3 so I am building 1.8.0 to get support for Geospatial PDF files. See http://www.gdal.org/frmt_pdf.html -- there are links to further documentation and sample GeoPDF's at the bottom of this page.

Downloaded RC2 tarball.

This gets me what I need (there are many more options). Poppler is for PDF support

sudo apt-get install libproj-dev libpoppler-dev
./configure --with-python --with-poppler
make
sudo make install

Here we go!

JOY! It works!

Building gdal 1.7.3 so I can have gdal python bindings, so I can reclassify a raster. In another window, I am running a very simple ESRI Spatial Analyst reclassification, but it's taking so long that I can probably build gdal and write a python script to do the same thing before the ESRI tool completes.

(I assume the ESRI tool crashed but as usual, I have no way of knowing.)

I had to add C++ to my system. Compiling.

Oh -- gdal built successfully. Installing it. Done. Updated system path.

Trying to build Python bindings now, what a pain! In the meantime, I clicked "cancel" button, perhaps in a few hours I will know if ArcMap crashed or not. (See comment above about failure of cancel button to cancel...)
