Windows环境下编译Ceres

本文主要是介绍Windows环境下编译Ceres，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. 下载ceres稳定版本ceres-solver-1.14.0

2. 解压进入jni目录，修改Application.mk文件

#APP_BUILD_SCRIPT := $(call my-dir)/Android.mk
#APP_PROJECT_PATH := $(call my-dir)APP_CPPFLAGS += -fexceptions
APP_CPPFLAGS += -frtti
APP_OPTIM := release# Use libc++ from LLVM. It is a modern BSD licensed implementation of
# the standard C++ library.
APP_STL := gnustl_static
APP_ABI := arm64-v8a

3. 修改Android.mk文件

# Builds Ceres for Android, using the standard toolchain (not
# standalone). It uses LLVM's libc++ as the standard library. It is a
# modern BSD licensed implementation of the standard c++ library. We
# do this to avoid any licensing issues that may arise from using
# GCC's libstdc++ which is licensed under GPL3.
#
# Building
# --------
#
# 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.
#
# Using the library
# -----------------
# 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 increase the
# size of the binary. If you don't need them for your application,
# consider adding:
#
#   -DCERES_RESTRICT_SCHUR_SPECIALIZATION
#
# to the LOCAL_CFLAGS variable below.
#
# 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.LOCAL_PATH := $(call my-dir)# Ceres requires at least NDK version r9d to compile.
#ifneq ($(shell $(LOCAL_PATH)/assert_ndk_version.sh "r9d" $(NDK_ROOT)), true)
#  $(error Ceres requires NDK version r9d or greater)
#endif#EIGEN_PATH := $(EIGEN_PATH)
EIGEN_PATH := $(LOCAL_PATH)/../eigen
# Ceres requires Eigen to build.

3. 下载Eigine并配置到Android.mk中，jni的上级目录运行ndk-build.bat
