These pages describe how to install PROJ on your computer without compiling it yourself. Below are guides for installing on Windows, Linux and Mac OS X. This is a good place to get started if this is your first time using PROJ. More advanced users may want to compile the software themselves.
Installation from package management systems¶
PROJ is also available via cross platform package managers.
The conda package manager includes several PROJ packages. We recommend installing
conda install -c conda-forge proj
conda you can also install the PROJ grid packages. Here’s how to install
the proj-datumgrid-europe package:
conda install -c conda-forge proj-datumgrid-europe
Available is also the

The simplest way to install PROJ on Windows is to use the OSGeo4W software distribution. OSGeo4W provides easy access to many popular open source geospatial software packages. After installation you can use PROJ from the OSGeo4W shell. To install PROJ do the following:
If you have already installed software via OSGeo4W on your computer it is likely that PROJ is already installed.
Run the OSGeo4W setup program.
Select “Advanced Install” and press Next.
Select “Install from Internet” and press Next.
Select a installation directory. The default suggestion is fine in most cases. Press Next.
Select “Local package directory”. The default suggestion is fine in most cases. Press Next.
Select “Direct connection” and press Next.
Choose the download.osgeo.org server and press Next.
Find “proj” under “Commandline_Utilities” and click the package in the “New” column until the version you want to install appears.
Press next to install PROJ.
You should now have a “OSGeo” menu in your start menu. Within that menu you can find the “OSGeo4W Shell” where you have access to all the OSGeo4W applications, including proj.
For those who are more inclined to the command line, steps 2–10 above can be accomplished by executing the following command:
C:\temp\osgeo4w-setup-x86-64.exe -q -k -r -A -s https://download.osgeo.org/osgeo4w/ -a x86_64 -P proj
How to install PROJ on Linux depends on which distribution you are using. Below is a few examples for some of the more common Linux distributions:
On Debian and similar systems (e.g. Ubuntu) the APT package manager is used:
sudo apt-get install proj-bin
On Fedora the dnf package manager is used:
sudo dnf install proj
On Red Hat based system packages are installed with yum:
sudo yum install proj
Mac OS X¶
On OS X PROJ can be installed via the Homebrew package manager:
brew install proj
PROJ is also available from the MacPorts system:
sudo ports install proj
Compilation and installation from source code¶
The classic way of installing PROJ is via the source code distribution. The most recent version is available from the download page.
You will need that and at least the standard proj-datumgrid package for a successful installation.
The following guides show how to compile and install the software using the Autotools and CMake build systems.
SQLite3 >= 3.11 (headers, library and executable)
GNU make for autotools build or CMake >= 3.5
FSF’s configuration procedure is used to ease installation of the PROJ system.
The Autotools build system is only available on UNIX-like systems. Follow the CMake installation guide if you are not using a UNIX-like operating system.
The default destination path prefix for installed files is
Results from the installation script will be placed into subdirectories
man/man3. If this default path prefix
is proper, then execute:
If another path prefix is required, then execute:
In either case, the directory of the prefix path must exist and be writable by the installer.
Before proceeding with the installation we need to add the datum grids. Unzip
the contents of the proj-datumgrid package into
unzip proj-datumgrid-1.7.zip -d proj-5.0.1/data/
The installation will automatically move the grid files to the correct location.
Alternatively the grids can be installed manually in the directory pointed to
PROJ_LIB environment variable. The default location is
With the grid files in place we can now build and install PROJ:
make make install
The install target will create, if necessary, all required sub-directories.
Tests are run with:
The test suite requires that the proj-datumgrid package is installed in
With the CMake build system you can compile and install PROJ on more or less any platform. After unpacking the source distribution archive step into the source- tree:
Create a build directory and step into it:
mkdir build cd build
From the build directory you can now configure CMake and build the binaries:
cmake .. cmake --build .
On Windows, one may need to specify generator:
cmake -G "Visual Studio 15 2017" ..
If the SQLite3 dependency is installed in a custom location, specify the paths to the include directory and the library:
cmake -DSQLITE3_INCLUDE_DIR=/opt/SQLite/include -DSQLITE3_LIBRARY=/opt/SQLite/lib/libsqlite3.so ..
Alternatively, the custom prefix for SQLite3 can be specified:
cmake -DCMAKE_PREFIX_PATH=/opt/SQLite ..
Tests are run with:
The test suite requires that the proj-datumgrid package is installed
