Building NetCDF with CMake
|
|
**************************
|
|
|
|
This document describes how to use CMake to configure and build the
|
|
NetCDF-C libraries across different platforms.
|
|
|
|
************
|
|
Introduction
|
|
************
|
|
|
|
We have recently introduced CMake support into the NetCDF trunk. Using
|
|
CMake, it is possible to build the NetCDF libraries natively on
|
|
Windows using Visual Studio. CMake also provides an alternative build
|
|
system to autotools. CMake works on Unix, Linux and Windows system,
|
|
and will generate files for a variety of build systems.
|
|
|
|
- Operating System: Any/All: Unix Makefiles, CodeBlocks, Eclipse CDT
|
|
- Windows: Borland Makefiles, MSYS Makefiles, MinGW Makefiles, Visual
|
|
- Studio Projects (Versions 6+) Linux: Ninja, KDevelop3 OSX: Xcode

Requirements for building with CMake
|
|
************************************
|
|
|
|
1. NetCDF (4.2.x) with CMake support:
|
|
a) Subversion: svn co
|
|
http://svn.unidata.ucar.edu/repos/netcdf/trunk netcdf
|
|
2. CMake 2.8.8+ for your platform of choice. http://www.cmake.org
|
|

Out-of-source Builds
|
|
********************
|
|
|
|
The CMake build system discourages 'in-source' builds. Instead, a
|
|
build directory is created and used to contain the output of the build
|
|
process. From the command line, this may be achieved as follows:
|
|
|
|
developer@dummy-machine:/netcdf$ mkdir build_dir
|
|
developer@dummy-machine:/netcdf$ cd build_dir
|
|
developer@dummy-machine:/netcdf/build_dir$ cmake ..
|
|
|
|
|
|
Compiling and Testing the NetCDF Libraries and Utilities
|
|
********************************************************
|
|
|
|
CMake provides different 'Generators'; these define the build system
|
|
which will be used to build the NetCDF libraries. On Unix/Linux, the
|
|
default generator is 'Unix Makefiles':
|
|
|
|
developer@dummy-machine:/netcdf/build_dir$ cmake ..
|
|
developer@dummy-machine:/netcdf/build_dir$ make
|
|
developer@dummy-machine:/netcdf/build_dir$ make test
|
|
|
|
On windows, the default generator is for Visual Studio based
|
|
builds. CMake is invoked the same way: C:\netcdf\build_dir>cmake ..
|
|
|
|
The resulting project files can be opened in Visual Studio, or you
|
|
can compile from the command line using CMake as an intermediary:
|
|
|
|
C:\netcdf\build_dir>cmake --build .
|
|
|
|
Note: If you want to use a different generator than the default, you
|
|
would specify it with the '-G' flag.
|
|
|
|
Common NetCDF/CMake Options
|
|
*********************
|
|
|
|
- ENABLE_NETCDF_4 (On by Default)
|
|
- ENABLE_DAP (On by Default)
|
|
- BUILD_SHARED_LIBS (Off by Default for Windows,
|
|
On by Default for Unix/Linux)
|
|
- ENABLE_DLL (Windows Only, Off by Default)
|
|
- CMAKE_PREFIX_PATH (Specify list of
|
|
|
|
This is just a partial list of options available. To see a full list
|
|
of options, run 'cmake -L' from the command line, or use a CMake GUI.
|
|
|
|
To specify an option with CMake, you would use the following syntax:
|
|
|
|
developer@dummy-machine:/netcdf/build_dir$ cmake .. -D"ENABLE_NETCDF_4=ON"
|
|
-D"BUILD_SHARED_LIBS=ON" -D"USE_HDF5=OFF"
|
|
|
|

CMake is a very robust build system. For additional syntax and
|
|
options, see the CMake website, FAQ and Wiki available at
|
