QGIS, like a number of major projects (eg. KDE 4.0), uses CMake
(http://www.cmake.org) for building from source.
Following a summary of the required dependencies for building:
Required build tools:
- CMake >= 2.8.6
- Flex >= 2.5.6
- Bison >= 2.4
-
Required build dependencies:
- Qt >= 4.7.0
- Proj >= 4.4.x
- GEOS >= 3.0
- Sqlite3 >= 3.0.0
- GDAL/OGR >= 1.4.x
- Qwt >= 5.0 & (< 6.1 with internal QwtPolar)
- expat >= 1.95
- QScintilla2
-
Optional dependencies:
- for GRASS plugin - GRASS >= 6.0.0 (libraries compiled with exceptions support on Linux 32bit)
- for georeferencer - GSL >= 1.8
- for postgis support and SPIT plugin - PostgreSQL >= 8.0.x
- for gps plugin - gpsbabel
- for mapserver export and PyQGIS - Python >= 2.3 (2.5+ preferred)
- for python support - SIP >= 4.12, PyQt >= 4.8.3 must match Qt version, Qscintilla2
- for qgis mapserver - FastCGI
- for oracle provider - Oracle OCI library
-
Indirect dependencies:
Some proprietary formats (eg. ECW and MrSid) supported by GDAL require
proprietary third party libraries. QGIS doesn't need any of those itself to
build, but will only support those formats if GDAL is built accordingly. Refer
to http://gdal.org/formats_list.html ff. for instructions how to include
those formats in GDAL.
