ubuntu安装openMVS遇到的问题

问题1：

/home/zll/library/openMVS/libs/MVS/PatchMatchCUDA.cu(267): error: calling a __host__ function("Eigen::MatrixBase< ::Eigen::Matrix<float, (int)3, (int)3, (int)0, (int)3, (int)3> > ::inverse() const") from a __device__ function("ComputeHomography") is not allowed

/home/zll/library/openMVS/libs/MVS/PatchMatchCUDA.cu(267): error: identifier "Eigen::MatrixBase< ::Eigen::Matrix<float, (int)3, (int)3, (int)0, (int)3, (int)3> > ::inverse const" is undefined in device code

2 errors detected in the compilation of "/home/zll/library/openMVS/libs/MVS/PatchMatchCUDA.cu".
make[2]: *** [libs/MVS/CMakeFiles/MVS.dir/build.make:317：libs/MVS/CMakeFiles/MVS.dir/PatchMatchCUDA.cu.o] 错误 1
make[2]: *** 正在等待未完成的任务....

解决方法：

Eigen3.3.9不行，换Eigen3.4
