在Code::块中使用CGAL
Using CGAL with Code::Blocks
我试着运行这段代码，但是我得到了很多undefined reference错误。
这是错误日志:

为什么我得到undefined reference错误?
如果你正在使用ros，你需要在cmake文件中添加你正在使用的库。
在您的情况下，只需在编译时在文件名后添加-lCGAL -lgmp -frounding-math。
我在使用CMake编译CGAL示例时遇到了类似的链接错误。我可以用
解决它 target_link_libraries(example CGAL::CGAL)而不是使用CMake变量
target_link_libraries(example ${CGAL_LIBRARIES})
