ubuntu1604安装ceres库

提前安装engin3

编译ceres时：error: ‘integer_sequence’ is not a member of ‘std‘错误

视觉slam十四讲第六章中，按照上安装的ceres库版本，以及网上大多数教程安装的版本都会和eigen3（3.3.7）有冲突，编译时会报如下错误：

这里换成1.14.0版本的ceres问题得以解决;
1.先删除之前的ceres-solver：

sudo rm -r /usr/local/lib/cmake/Ceres
sudo rm -rf /usr/local/include/ceres /usr/local/lib/libceres.a
sudo rm -r /usr/local/share/Ceres

2.下载ceres-solver-1.14.0

wget ceres-solver.org/ceres-solver-1.14.0.tar.gz

3.解压

tar xvf ceres-solver-1.14.0.tar.gz

4.编译

cd ceres-solver-1.14.0
mkdir build
cd build
cmake ..
make -j4
make test

5.安装

sudo make install

6.编译ceres_curve_fiiting
cd到ceres_curve_fiiting文件夹下

 mkdir build
   cd build
   cmake ..
   make
   ./curve_fitting

 

成功编译！
