It uses LLVM's libc++ as the standard library. It is a 34 # modern BSD licensed implementation of the standard c++ library. We 35 # do this to avoid any licensing issues that may arise from using 36 # GCC's libstdc++ which is licensed under GPL3. 37 # 38 # Building 39 # -------- 40 # 41 # You will have to specify the environment EIGEN_PATH to point to the 42 # Eigen sources when building. For example: 43 # 44 # EIGEN_PATH=/home/keir/src/eigen-3.0.5 ndk-build -j 45 # 46 # It is also possible to specify CERES_EXTRA_DEFINES, in case you need 47 # to pass more definitions to the C compiler. 48 # 49 # Using the library 50 # ----------------- 51 # Copy the static library: 52 # 53 # ../obj/local/armeabi-v7a/libceres.a 54 # 55 # into your own project, then link it into your binary in your 56 # Android.mk file. 57 # 58 # Reducing binary size 59 # -------------------- 60 # This build includes the Schur specializations, which increase the 61 # size of the binary. If you don't need them for your application, 62 # consider adding: 63 # 64 # -DCERES_RESTRICT_SCHUR_SPECIALIZATION 65 # 66 # to the LOCAL_CFLAGS variable below. 67 # 68 # Changing the logging library 69 # ---------------------------- 70 # Ceres Solver ships with a replacement for glog that provides a 71 # simple and small implementation that builds on Android. However, if 72 # you wish to supply a header only version yourself, then you may 73 # define CERES_GLOG_DIR to point to it. 74 75 LOCAL_PATH := $(call my-dir) 76 77 EIGEN_PATH := external/eigen 78 CERES_INCLUDE_PATHS := $(CERES_EXTRA_INCLUDES) 79 CERES_INCLUDE_PATHS += $(LOCAL_PATH)/internal 80 CERES_INCLUDE_PATHS += $(LOCAL_PATH)/internal/ceres 81 CERES_INCLUDE_PATHS += $(LOCAL_PATH)/include 82 CERES_INCLUDE_PATHS += $(LOCAL_PATH)/config 83 84 # Use the alternate glog implementation if provided by the user. 85 ifdef CERES_GLOG_DIR 86 CERES_INCLUDE_PATHS += $(CERES_GLOG_DIR) 87 else 88 CERES_INCLUDE_PATHS += $(LOCAL_PATH)/internal/ceres/miniglog 89 endif 90 CERES_SRC_PATH := internal/ceres 91 92 93 include $(CLEAR_VARS) 94 LOCAL_C_INCLUDES := $(CERES_INCLUDE_PATHS) 95 LOCAL_C_INCLUDES += $(EIGEN_PATH) 96 97 LOCAL_SDK_VERSION := 17 98 LOCAL_NDK_STL_VARIANT := c++_static 99 100 LOCAL_CPP_EXTENSION := .cc 101 LOCAL_CFLAGS := $(CERES_EXTRA_DEFINES) \ 102 -DCERES_NO_LAPACK \ 103 -DCERES_NO_SUITESPARSE \ 104 -DCERES_NO_THREADS \ 105 -DCERES_NO_CXSPARSE \ 106 -DCERES_STD_UNORDERED_MAP 107 108 # The default relase optimization level is O2, but we want O3. 109 LOCAL_CFLAGS += -O3 -w 110 111 # Set the logging max level to 1. 112 LOCAL_CFLAGS += -DMAX_LOG_LEVEL=-1 113 114 # On Android NDK 8b, GCC gives spurrious warnings about ABI incompatibility for 115 # which there is no solution.
