E.5 SQLite3 E.5. SQLite3 SQLite3 is used to manage the projections database and store persistent data such as spatial bookmarks. Download the latest (3.x) version of SQLite from http://www.sqlite.org/ (9). Untar the distribution and: ./configure make make install Note: SQLite 3.x is included on Mac OS X 10.4. E.6. GDAL/OGR The GDAL and OGR libraries provide support for raster and vector data formats. QGIS makes use of both of these libraries (which come bundled in one distribution). Note: A GNU/Linux binary of GDAL is available athttp://www.gdal.org. If you choose to install the binary you will also need to download and unpack the source tree since QGIS needs the header files in order to compile. To install GDAL/OGR from source: 1. Download the GDAL distribution from http://www.gdal.org (3). You should use the latest version of GDAL if possible. The minimum recommended version for use with QGIS 0.8 is 1.3.1. 2. Untar the distribution tar xfvz /path/to/gdal-x.x.x.tar.gz 3. Change to the gdal-x.x.x subdirectory that was created by step 2 cd gdal-x.x.x 4. Configure GDAL ./configure Since GDAL/OGR supports a lot of different formats you should check to website (see (3) for other dependencies required by GDAL/OGR. It may possible that you need more libraries and its header-files installed in order to get a specific format linked into GDAL/OGR. QGIS 0.8 User Guide 99
E.7 GRASS 5. Build and install GDAL: make sudo make install 6. In order to run GDAL after installing it is necessary for the shared library to be findable. This can often be accomplished by setting LD_LIBRARY_PATH to include /usr/local/lib. On Linux, you can add /usr/local/lib (or whatever path you used for installing GDAL) to /etc/ld.so.conf and run ldconfig as root afterwards. 7. Make sure that gdal-config (found in the bin subdirectory where GDAL was installed) is included in the PATH. If necessary, add the path to gdal-config to the PATH environment variable. export PATH=/path/to/gdal-config:$PATH 8. Check the install by running: gdal-config --formats If you’ve had problems during the installation, refer to this manual, where the whole process is described with some more detail: http://www.gdal.org/gdal_building.html Note: In order to get GRASS-support into QGIS you need to compile the GRASS-plugins for GDAL and OGR as well. Please see section E.8 for more details. E.7. GRASS If you want QGIS to support GRASS vector and raster layers, you must build GRASS prior to proceeding. Follow the directions on the GRASS website carefully to at least version, 6.0.x, better version 6.x.x from CVS. Additional information and the build instructions can be found at http://grass.itc.it. The GRASS software is available for download at http://grass.itc.it/download/index.php. E.8. gdal-GRASS-plugins To enable GRASS raster-support in QGIS, the GDAL-plugin for GRASS needs to be built. You need the header-files from GRASS and GDAL/OGR in order to build the plugins. QGIS 0.8 User Guide 100
