我没有写cmaklist,而是直接手动编译g++ cMatrix.cpp NavFunc.cpp main.cpp -o main,但还是报错...尝试了很多方法依然不行.
希望可以得到你的帮助 @YibinWu

void getIMUparas(IMU_ConstPara * IMU, cv::FileStorage fs, cv::FileNode IMU_paras)
{
cv::FileNodeIterator it1 = IMU_paras.begin();
cv::FileNodeIterator it = ++IMU_paras.begin();
cv::FileNodeIterator it2 = --IMU_paras.end();
std::vector leverarm, odo_std;
标粗的代码出现以下问题：一元“--”:“cv::FileNodeIterator”不定义该运算符或到预定义运算符可接收类型的转换
请问是否遇到过同样的问题，如果遇到过，是如何解决的。感谢。

How to run? Do you have cmakelists?
