问题：

Sophus/sophus/so2.cpp: In constructor ‘Sophus::SO2::SO2()’:
Sophus/sophus/so2.cpp:32:26: error: lvalue required as left operand of assignment
32 | unit_complex_.real() = 1.;
| ^~
Sophus/sophus/so2.cpp:33:26: error: lvalue required as left operand of assignment
33 | unit_complex_.imag() = 0.;
| ^~

解决

1.找到sophus/so2.cpp
2.注释掉

 unit_complex_.real() = 1.;
 unit_complex_.imag() = 0.;

改为

unit_complex_.real(1.);
unit_complex_.imag(0.);

即

SO2::SO2()
{
  //unit_complex_.real() = 1.;
  //unit_complex_.imag() = 0.;
  unit_complex_.real(1.);
  unit_complex_.imag(0.);
}
