ch4-Sophus编译报错

报错信息：

error: lvalue required as left operand of assignment
   unit_complex_.real() = 1.;
                          ^~
error: lvalue required as left operand of assignment
   unit_complex_.imag() = 0.;
                          ^~
CMakeFiles/Sophus.dir/build.make:65: recipe for target 'CMakeFiles/Sophus.dir/sophus/so2.cpp.o' failed

解决方法：修改Sophus下的so2.cpp文件

将下面这个修改一下：

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

修改为：

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

可能的解决方案：在Ubuntu虚拟机中运行OpenGL程序时，可能会遇到一些限制，因为虚拟机可能无法直接访问主机系统的显卡硬件。这可能导致OpenGL实现不支持较高版本的GLSL。要解决这个问题，您可以尝试以下方法：
- 启用3D加速：确保您的虚拟机软件（如VirtualBox、VMware等）已启用3D加速。这通常可以在虚拟机设置的显示或图形部分找到。启用3D加速后，虚拟机将尝试使用主机系统的显卡来提供更好的OpenGL支持。
- 安装虚拟机工具：确保您已安装了虚拟机软件提供的增强工具（如VirtualBox Guest Additions、VMware Tools等）。这些工具通常包含了针对虚拟机优化的图形驱动程序，可以提高OpenGL性能和兼容性。
- 使用软件渲染(我是通过这个解决的)：如果您无法启用3D加速或安装虚拟机工具，您可以尝试使用软件渲染。这将使用CPU而不是GPU来渲染OpenGL图形，性能可能较差，但可以提供更广泛的GLSL支持。在Ubuntu中，您可以安装Mesa的软件渲染器，例如llvmpipe。要安装llvmpipe，请运行以下命令：
```
sudo apt-get install libgl1-mesa-swx11
```
- 安装完成后，您可以通过设置LIBGL_ALWAYS_SOFTWARE=1环境变量来强制使用软件渲染：文章来源地址https://www.toymoban.com/news/detail-621762.html
```
export LIBGL_ALWAYS_SOFTWARE=1 
```
