It 33 # uses STLPort instead of GNU C++. This is useful for anyone wishing to ship 34 # GPL-free code. This cannot build the tests or other parts of Ceres; only the 35 # core libraries. If you need a more complete Ceres build, consider using the 36 # CMake toolchain (noting that the standalone toolchain doesn't work with 37 # STLPort). 38 # 39 # You will have to specify the environment EIGEN_PATH to point to the Eigen 40 # sources when building. For example: 41 # 42 # EIGEN_PATH=/home/keir/src/eigen-3.0.5 ndk-build -j 43 # 44 # It is also possible to specify CERES_EXTRA_DEFINES, in case you need to pass 45 # more definitions to the C compiler. 46 # 47 # IMPORTANT: 48 # 49 # The shared library built at the bottom is fake, broken, and empty. It exists 50 # only to force ndk-build to build the shared library. This shouldn't be 51 # necessary, but if it is missing, then ndk-build will do nothing when asked to 52 # build. The produced .so library is NON-FUNCTIONAL since it has no Ceres 53 # function-level dependencies. Instead, copy the static library: 54 # 55 # ../obj/local/armeabi-v7a/libceres.a 56 # 57 # into your own project, then link it into your binary in your Android.mk file. 58 # 59 # Reducing binary size: 60 # 61 # This build includes the Schur specializations, which cause binary bloat. If 62 # you don't need them for your application, consider adding: 63 # 64 # -DCERES_RESTRICT_SCHUR_SPECIALIZATION 65 # 66 # to the LOCAL_CFLAGS variable below, and commenting out all the 67 # generated/schur_eliminator_2_2_2.cc-alike files, leaving only the _d_d_d one. 68 69 70 # This file is for NDK use only. 71 72 LOCAL_PATH := $(call my-dir) 73 74 EIGEN_PATH := $(EIGEN_PATH) 75 76 CERES_SRC_PATH := ../internal/ceres 77 78 include $(CLEAR_VARS) 79 LOCAL_C_INCLUDES := ../internal \ 80 ../internal/ceres \ 81 ../include \ 82 ../internal/ceres/miniglog \ 83 $(EIGEN_PATH) 84 85 LOCAL_CPP_EXTENSION := .cc 86 LOCAL_CFLAGS := -DCERES_NO_PROTOCOL_BUFFERS \ 87 -DCERES_NO_SUITESPARSE \ 88 -DCERES_NO_GFLAGS \ 89 -DCERES_NO_THREADS \ 90 -DCERES_NO_CXSPARSE \ 91 -DCERES_NO_TR1 \ 92 -DCERES_WORK_AROUND_ANDROID_NDK_COMPILER_BUG 93 94 # On Android NDK 8b, GCC gives spurrious warnings about ABI incompatibility for 95 # which there is no solution.
