Third-Party Library Installation
Important Notes Specific to GTSAM
==================
GTSAM uses CCOLAMD to get a good elimination ordering for the linear solving.
CCOLAMD can be downloaded from Tim Davis's website:
http://www.cise.ufl.edu/research/sparse/ccolamd/
The package should be installed to the default C++ search path. To link properly
with the installed library, pass the following argument to ./configure (described
in the next section):
--with-ccolamd-lib=YOURPATH_TO_LIBCCOLAMD
1)
GTSAM uses CCOLAMD to find good variable elimination orders. You can download
it from Tim Davis's website: http://www.cise.ufl.edu/research/sparse/ccolamd/
Then, pass the following arguments (paths are just examples) to ./configure:
--with-ccolamd-inc=/usr/local/include
--with-ccolamd-lib=/usr/local/lib
For interneal usage of people **at Georgia Tech**, check out the "CCOLAMD" project
from the SVN server, and run "make install". The library will be installed
in $HOME/lib/ and $HOME/include/CCOLAMD by default. No additional configure argument
is needed for configure in this case.
2)
GTSAM makes extensive use of debug assertions, even for checking input of
the functions you will call. These assertions are disabled when NDEBUG is
defined. Thus, we strongly recommend compiling GTSAM and your own code without
this symbol during debugging.
After debugging, GTSAM will run much faster when compiled with NDEBUG defined,
so that debug checks are disabled.
Another useful debugging symbol is _GLIBCXX_DEBUG, which enables debug checks
and safe containers in the standard C++ library. We suggest testing your code
with this symbol defined, as it will make problems much easier to find.
NOTE: The native Snow Leopard g++ compiler/library contains a bug that makes
it impossible to use this symbol. The MacPorts g++ compilers work fine with it
though.
3)
Putting the above together, here are some sample ./configure commands for
compiling gtsam:
For Debugging (native Snow Leopard g++ compiler):
./configure CXXFLAGS="-fno-inline -g -Wall" \
LDFLAGS="-fno-inline -g -Wall" --enable-blas --enable-lapack \
--with-toolbox=$HOME/toolbox/
For Debugging (Linux or MacPorts g++ compilers):
./configure CXXFLAGS="-fno-inline -g -Wall -D_GLIBCXX_DEBUG" \
LDFLAGS="-fno-inline -g -Wall" --enable-blas --enable-lapack \
--with-toolbox=$HOME/toolbox/
For Performance:
../configure CXXFLAGS="-DNDEBUG -O3" LDFLAGS="-O3" --enable-blas \
--enable-lapack --with-toolbox=$HOME/toolbox/
