|  | # Builds Ceres for Android, using the standard toolchain (not standalone). It | 
|  | # uses STLPort instead of GNU C++. This is useful for anyone wishing to ship | 
|  | # GPL-free code. This cannot build the tests or other parts of Ceres; only the | 
|  | # core libraries. If you need a more complete Ceres build, consider using the | 
|  | # CMake toolchain (noting that the standalone toolchain doesn't work with | 
|  | # STLPort). | 
|  | # | 
|  | # You will have to specify the environment EIGEN_PATH to point to the Eigen | 
|  | # sources when building. For example: | 
|  | # | 
|  | #   EIGEN_PATH=/home/keir/src/eigen-3.0.5 ndk-build -j | 
|  | # | 
|  | # It is also possible to specify CERES_EXTRA_DEFINES, in case you need to pass | 
|  | # more definitions to the C compiler. | 
|  | # | 
|  | # IMPORTANT: | 
|  | # | 
|  | # The shared library built at the bottom is fake, broken, and empty. It exists | 
|  | # only to force ndk-build to build the shared library. This shouldn't be | 
|  | # necessary, but if it is missing, then ndk-build will do nothing when asked to | 
|  | # build. The produced .so library is NON-FUNCTIONAL since it has no Ceres | 
|  | # function-level dependencies. Instead, copy the static library: | 
|  | # | 
|  | #   ../obj/local/armeabi-v7a/libceres.a | 
|  | # | 
|  | # into your own project, then link it into your binary in your Android.mk file. | 
|  | # | 
|  | # Reducing binary size: | 
|  | # | 
|  | # This build includes the Schur specializations, which cause binary bloat. If | 
|  | # you don't need them for your application, consider adding: | 
|  | # | 
|  | #   -DCERES_RESTRICT_SCHUR_SPECIALIZATION | 
|  | # | 
|  | # to the LOCAL_CFLAGS variable below, and commenting out all the | 
|  | # generated/schur_eliminator_2_2_2.cc-alike files, leaving only the _d_d_d one. | 
|  | # | 
|  | # Similarly if you do not need the line search minimizer, consider adding | 
|  | # | 
|  | #   -DCERES_NO_LINE_SEARCH_MINIMIZER | 
|  | # | 
|  | # Changing the logging library: | 
|  | # | 
|  | # Ceres Solver ships with a replacement for glog that provides a | 
|  | # simple and small implementation that builds on Android. However, if | 
|  | # you wish to supply a header only version yourself, then you may | 
|  | # define CERES_GLOG_DIR to point to it. |
