ceres下载
在ubuntu18.04版本中安装2.2.0版本存在很多问题,下载2.1.0或者更早的1.14.0可以跳过很多麻烦。
法1:在官网installation的Getting the source code章节,直接点击"the latest stable release"。
法2:在ubuntu的bash中使用wge下载:[适合于下载指定的版本]
bash
wget http://ceres-solver.org/ceres-solver-2.2.0.tar.gz
wget http://ceres-solver.org/ceres-solver-2.1.0.tar.gz
wget http://ceres-solver.org/ceres-solver-1.14.0.tar.gz

mkdir build
cd build
# 执行cmake, 这里设置了ceres的安装目录是/usr/local/ceres,可根据个人情况指定
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PRE_FIX=/usr/local/ceres ..
# -j3是使用3个cpu core来编译,根据个人CPU的个数给定,也可以去掉-j3
make -j3
# make test不是必须的
make test
# Optionally install Ceres, it can also be exported using CMake which
# allows Ceres to be used without requiring installation, see the documentation
# for the EXPORT_BUILD_DIR option for more information.
sudo make install
