Quickstart
 | 
						|
 | 
						|
In the root library folder execute:
 | 
						|
 | 
						|
$] mkdir build
 | 
						|
$] cd build
 | 
						|
$] cmake ..
 | 
						|
$] make check (optional, runs unit tests)
 | 
						|
$] make install
 | 
						|
 | 
						|
Important Installation Notes
 | 
						|
----------------------------
 | 
						|
 | 
						|
1)
 | 
						|
GTSAM requires the following libraries to be installed on your system:
 | 
						|
 - BOOST version 1.43 or greater (install through Linux repositories or MacPorts)
 | 
						|
 - Cmake version 2.6 or higher
 | 
						|
 - Support for XCode 4.3 command line tools on Mac requires CMake 2.8.8 or higher
 | 
						|
 | 
						|
Optional dependent libraries:
 | 
						|
 - If TBB is installed and detectable by CMake GTSAM will use it automatically.
 | 
						|
   Ensure that CMake prints "Use Intel TBB : Yes".  To disable the use of TBB,
 | 
						|
   disable the CMake flag GTSAM_WITH_TBB (enabled by default).  On Ubuntu, TBB
 | 
						|
   may be installed from the Ubuntu repositories, and for other platforms it
 | 
						|
   may be downloaded from https://www.threadingbuildingblocks.org/
 | 
						|
 | 
						|
Tested compilers:
 | 
						|
 | 
						|
- GCC 4.2-4.7
 | 
						|
- OSX Clang 2.9-5.0
 | 
						|
- OSX GCC 4.2
 | 
						|
- MSVC 2010, 2012
 | 
						|
 | 
						|
Tested systems:
 | 
						|
 | 
						|
- Ubuntu 11.04 - 13.10
 | 
						|
- MacOS 10.6 - 10.9
 | 
						|
- Windows 7, 8, 8.1
 | 
						|
 | 
						|
Known issues:
 | 
						|
 | 
						|
- MSVC 2013 is not yet supported because it cannot build the serialization module
 | 
						|
  of Boost 1.55 (or earlier). 
 | 
						|
 | 
						|
2)
 | 
						|
GTSAM makes extensive use of debug assertions, and we highly recommend you work
 | 
						|
in Debug mode while developing (enabled by default). Likewise, it is imperative
 | 
						|
that you switch to release mode when running finished code and for timing. GTSAM
 | 
						|
will run up to 10x faster in Release mode! See the end of this document for 
 | 
						|
additional debugging tips.
 | 
						|
 | 
						|
3)
 | 
						|
GTSAM has Doxygen documentation. To generate, run 'make doc' from your
 | 
						|
build directory.
 | 
						|
 | 
						|
4)
 | 
						|
The instructions below install the library to the default system install path and
 | 
						|
build all components. From a terminal, starting in the root library folder, 
 | 
						|
execute commands as follows for an out-of-source build:
 | 
						|
 | 
						|
$] mkdir build
 | 
						|
$] cd build
 | 
						|
$] cmake ..
 | 
						|
$] make check (optional, runs unit tests)
 | 
						|
$] make install
 | 
						|
 | 
						|
This will build the library and unit tests, run all of the unit tests, 
 | 
						|
and then install the library itself.
 | 
						|
 | 
						|
- CMake Configuration Options and Details
 | 
						|
 | 
						|
GTSAM has a number of options that can be configured, which is best done with
 | 
						|
one of the following:
 | 
						|
 | 
						|
  ccmake      the curses GUI for cmake
 | 
						|
  cmake-gui   a real GUI for cmake
 | 
						|
 | 
						|
Important Options: 
 | 
						|
 | 
						|
CMAKE_BUILD_TYPE: We support several build configurations for GTSAM (case insensitive)
 | 
						|
  Debug (default)  All error checking options on, no optimization. Use for development.
 | 
						|
  Release          Optimizations turned on, no debug symbols.           
 | 
						|
  Timing           Adds ENABLE_TIMING flag to provide statistics on operation 
 | 
						|
  Profiling        Standard configuration for use during profiling
 | 
						|
  RelWithDebInfo   Same as Release, but with the -g flag for debug symbols
 | 
						|
 | 
						|
CMAKE_INSTALL_PREFIX: The install folder. The default is typically /usr/local/
 | 
						|
To configure to install to your home directory, you could execute:
 | 
						|
$] cmake -DCMAKE_INSTALL_PREFIX:PATH=$HOME ..
 | 
						|
 | 
						|
GTSAM_TOOLBOX_INSTALL_PATH: The Matlab toolbox will be installed in a subdirectory
 | 
						|
of this folder, called 'gtsam'.
 | 
						|
$] cmake -DGTSAM_TOOLBOX_INSTALL_PATH:PATH=$HOME/toolbox ..
 | 
						|
 | 
						|
GTSAM_BUILD_CONVENIENCE_LIBRARIES: This is a build option to allow for tests in 
 | 
						|
subfolders to be linked against convenience libraries rather than the full libgtsam. 
 | 
						|
Set with the command line as follows:
 | 
						|
$] cmake -DGTSAM_BUILD_CONVENIENCE_LIBRARIES:OPTION=ON ..
 | 
						|
  ON (Default)   This builds convenience libraries and links tests against them. This 
 | 
						|
  				 option is suggested for gtsam developers, as it is possible to build 
 | 
						|
  				 and run tests without first building the rest of the library, and 
 | 
						|
  				 speeds up compilation for a single test. The downside of this option 
 | 
						|
  				 is that it will build the entire library again to build the full 
 | 
						|
  				 libgtsam library, so build/install will be slower.
 | 
						|
  OFF            This will build all of libgtsam before any of the tests, and then 
 | 
						|
  				 link all of the tests at once. This option is best for users of GTSAM, 
 | 
						|
  				 as it avoids rebuilding the entirety of gtsam an extra time. 
 | 
						|
 | 
						|
GTSAM_BUILD_UNSTABLE: Enable build and install for libgtsam_unstable library. 
 | 
						|
Set with the command line as follows:
 | 
						|
$] cmake -DGTSAM_BUILD_UNSTABLE:OPTION=ON ..
 | 
						|
  ON             When enabled, libgtsam_unstable will be built and installed with the 
 | 
						|
                 same options as libgtsam.  In addition, if tests are enabled, the 
 | 
						|
                 unit tests will be built as well.  The Matlab toolbox will also
 | 
						|
                 be generated if the matlab toolbox is enabled, installing into a 
 | 
						|
                 folder called "gtsam_unstable".
 | 
						|
  OFF (Default)  If disabled, no gtsam_unstable code will be included in build or install. 
 | 
						|
 | 
						|
Check
 | 
						|
 | 
						|
"make check" will build and run all of the tests. Note that the tests will only be 
 | 
						|
built when using the "check" targets, to prevent "make install" from building the tests
 | 
						|
unnecessarily. You can also run "make timing" to build all of the timing scripts. 
 | 
						|
To run check on a particular module only, run "make check.[subfolder]", so to run
 | 
						|
just the geometry tests, run "make check.geometry". Individual tests can be run by
 | 
						|
appending ".run" to the name of the test, for example, to run testMatrix, run 
 | 
						|
"make testMatrix.run". 
 | 
						|
 | 
						|
MEX_COMMAND: Path to the mex compiler. Defaults to assume the path is included in your 
 | 
						|
shell's PATH environment variable. mex is installed with matlab at 
 | 
						|
$MATLABROOT/bin/mex
 | 
						|
 | 
						|
$MATLABROOT can be found by executing the command 'matlabroot' in MATLAB
 | 
						|
 | 
						|
Debugging tips:
 | 
						|
 | 
						|
Another useful debugging symbol is _GLIBCXX_DEBUG, which enables debug checks
 | 
						|
and safe containers in the standard C++ library and makes problems much easier
 | 
						|
to find.
 | 
						|
 | 
						|
NOTE:  The native Snow Leopard g++ compiler/library contains a bug that makes
 | 
						|
it impossible to use _GLIBCXX_DEBUG.  MacPorts g++ compilers do work with it though.
 | 
						|
 | 
						|
NOTE:  If _GLIBCXX_DEBUG is used to compile gtsam, anything that links against
 | 
						|
gtsam will need to be compiled with _GLIBCXX_DEBUG as well, due to the use of
 | 
						|
header-only Eigen.
