查了一下，大致说是ceres-solver和eigen3不兼容引起的，跑vins-mono时不能使用最新的ceres版本。
没办法，只好先卸载掉先前的2.0.0版本。
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
然后到这里下载1.14.0的版本，
wget ceres-solver.org/ceres-solver-1.14.0.tar.gz
https://ceres-solver.googlesource.com/ceres-solver
cd ceres-solver-1.14.0
mkdir build
cd build
cmake ..
make -j4
make test
sudo make install
编译ceres_curve_fiiting
cd到ceres_curve_fiiting文件夹下
mkdir build
cd build
cmake ..
make
./curve_fitting
编译结束！
