Issue presented here: PX4/PX4-Autopilot#2419

Hello everyone! I am working on implementing a tool to assess the complexity of CPU architecture porting. It primarily focuses on RISC-V architecture porting.In fact, it can be estimated on average across various architectures. As part of my dataset, I have collected the eigen project. I would like to gather community opinions to support my assessment. I appreciate your help and response! Based on scanning tools, the porting complexity is determined to be moderate, with a moderate amount of code related to the CPU architecture in the project.Even if I have already obtained the transplant, I only focus on the workload and difficulty of the entire transplant process, including the past and future. It would require a professional person ,to handle this task.(referring to the overall workload from adapting the project to a specific architecture to achieving full functionality on that architecture). Is this assessment accurate? I look forward to your help and response.

im using the latest vs version.
#include "Eigen/Dense"
Eigen::Matrix4f mat;
mat.rol(1);

i tried to use blockmethod in vs ,but the vs intellisense threw a lot of error;
navigating to the related file blockmethod.h,theres so many red errors, somthing like "block " is not a template, “Derived” is not an identifier...

how can i fix this?

I am using PyICP github repo. I built the Sophus from this commit (commit a0fe89a323e20c42d3cecb590937eb7a06b8343a) Reference.
I am using Ubuntu 22 and used virtual environment (venv with python version 3.7.14) to build the PyICP repo, minisam and Sophus repo.

Finally when I run the command python3 main_icp_slam.py it runs in this error.

I am not sure is it caused by Sophus, Eigen, Venv or minisam.

Let me know if anymore information is needed.

Thanks, for any and all the help.

Hello
Good time
In the code blocks for this code
It gives this error. Do you know what to do for this problem?

code: #include <Eigen/Cholesky>
error: error: Eigen/Cholesky: No such file or directory|

Problem:

When building the project, an error message is encountered: "‘std::optional’ is only available from C++17 onwards". This error occurs because the project uses the std::optional feature, which is available in C++17 and later versions, but the project is not configured to use C++17.

Solution:

To resolve this issue, set the C++ standard to C++17 in the project's CMakeLists.txt file by adding the following lines:

set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS OFF)

These lines configure the project to use C++17, make it a required standard, and disable compiler-specific extensions. After adding these lines to the CMakeLists.txt file, re-run the CMake command to configure the project. The project should now be compiled using C++17, and the error related to std::optional should be resolved.
