问题一:
Ubuntu安装Sophus报错：so2.cpp：error: lvalue required as left operand of assignment. unit_complex_.real() = 1.;
遇到的问题：
/Sophus/sophus/so2.cpp:32:26: error: lvalue required as left operand of assignment
unit_complex_.real() = 1.;
/Sophus/sophus/so2.cpp:33:26: error: lvalue required as left operand of assignment
unit_complex_.imag() = 0.;
解决办法：
找到/Sophus/sophus目录下so2.cpp文件，如下代码：
SO2::SO2()
{
unit_complex_.real() = 1.;
unit_complex_.imag() = 0.;
}
将其修改为：
SO2::SO2()
{
unit_complex_.real(1.);
unit_complex_.imag(0.);
}
问题二：
ros版本plc安装
sudo apt-get install ros-meodicc-pcl-ros
