Building PostGIS using Visual C++

Posted on by

I don’t like MinGW. I’ve been dreaming about building PostGIS using Visual C++ – the native development toolset for Windows platform – without being forced to install Unix-like environment inside Windows. Finally, I’ve got motivated enough and decided to make my dreams reality, so here is the story.

First, I collected all run-time dependencies required by PostGIS. I intentionally used the word run-time to indicate I’m not going to install MinGW neither Cygwin or any other GCC-for-Windows package. GNU make is also not required.

I use PostGIS source code from trunk in the Subversion repository.

Dependencies

There are only 3 software packages required:

  1. PostgreSQL 8.3.6 – official Win32 binaries and source code
  2. GEOS – build from sources, it’s safe to grab SVN trunk
  3. PROJ.4 – also build from sources and also from SVN trunk

I installed the PostgreSQL 8.3.6 without PostGIS extensions, as I’m going to provide my own :-), using default location c:\Program Files\PostgreSQL\8.3. The source code of PostgreSQL 8.3.6 went to d:\dev\postgresql\postgresql-8.3.6.

Short note on directories layout using for projects downloaded directly from repositories. Root path of source tree of each project have the same layout: D:\dev\PROJECT\_svn\trunk. For Visual Studio projects, these paths are defined as macros in postgis.vsprops (Visual C++ Property Sheet), so it should be easy to redefine them without any need to hack other project settings like Additional Include Directories and others.

libgeotiff 1.2.5 has been released.

Libgeotiff is an open source library normally hosted on top of libtiff for reading, and writing GeoTIFF information tags.

As officially announced, the new version includes a few bug fixes and improvements, coordinate systems dictionaries have been updated to EPSG 6.17 dataset.

There is also a new feature called Simple Tags Interface to make it easier to use libgeotiff to process geotiff tags in other file format. This new interface is used in libLAS to support LAS files georeferencing.

Packages of libgeotiff 1.2.5 are hosted on OSGeo Download server:

A week ago, Frank Warmerdam proposed to make GeoTIFF a subproject of OSGeo MetaCRS project, because of a few reasons:

  • libgeotiff is primary about CRS management
  • it is too small project to join OSGeo on it’s own
  • EPSG handling provided by libgeotiff is foundational number of FOSS4G projects (GDAL, QGIS, PROJ.4 and PostGIS, libLAS)

Motion: Libgeotiff as a MetaCRS sub-project was not waiting long and eventually has gained full acceptance from Project Steering Committee of MetaCRS, means passed.

Since July 28, 2008 GeoTIFF project is now a part of MetaCRS initiative lead by OSGeo community.
