Problems writing MPC programs using eigen,osqp,osqp-eigen in VS2015

[DRETQ]

Can anyone tell me what the problem is?

[S-Dafarra]

Hi @DRETQ, can you describe:

• The version of osqp-eigen and osqp you used
• The command and the compiler you used for compiling the project?
  Thanks!

[DRETQ]

@S-Dafarra The version of osqp-eigen is 0.8.1, the version of osqp is 0.6.3，I used the debug x86 local windows debugger command and the compiler is cmake.

[S-Dafarra]

Given the error message, the problem seems similar to #162 (comment)

Are you 100% sure you did not accidentally used osqp master branch? Because this error is exactly what you get if you are compiling against osqp master on Windows, see #146 and osqp/osqp#576 for the actual issue tracking the problem.

Also, can you report the CMakeCache.txt of both osqp and osqp-eigen to understand if something is going wrong?

One possible attempt is to try using the master version of osqp-eigen given that #163 should have fixed the issue.

One final remark, please avoid pasting screenshots of errors, but rather copy and paste them. This would allow others to find the same solution by searching for the same error online, and would allow me to translate errors more easily.

CMakeCache(osqp).txt
CMakeCache(osqp-eigen).txt
Thanks for your reply, what is the master version of osqp-eigen? I apologize for any inconvenience caused by the use of screenshots.

[S-Dafarra]

Could you do

cd E:/LibraryVS15/osqp-master/osqp
git log -1

and post the output?

Thanks for your reply, what is the master version of osqp-eigen?

You can do

cd E:/LibraryVS15/osqp-eigen-master
git checkout master
git pull

and then compile again

[S-Dafarra]

How did you clone (download) the repo?

[DRETQ]

@S-Dafarra Do you mean how do I download osqp,osqp-eigen, I run the command from cmd to download online

[S-Dafarra]

I run the command from cmd to download online

Just to understand, which command?

From #169 (comment) it seems that you don't have git installed

[DRETQ]

@S-Dafarra Commands used when installing osqp is :git clone --recursive -b release-0.6.3 https://github.com/oxfordcontrol/osqp.git. Configuring eigen,osqp,osqp-eigen on vs2015 should be successful because the official example file MPCExample given is able to run successfully.

[S-Dafarra]

Ok, then it seems you have git installed somewhere. Using the same application you used to do git clone, do also the commands I mentioned in #169 (comment)

[DRETQ]

@S-Dafarra You mean you want me to use git clone instead of git. Here are the results.

[DRETQ]

@S-Dafarra I found inconsistencies in reporting errors on vs2015 and vs2022，the osqp,eigen,osqp-eigen configured in it are the same.

[S-Dafarra]

@S-Dafarra You mean you want me to use git clone instead of git.

No, I meant to run the commands I posted above in a terminal where git can be used

[DRETQ]

@S-Dafarra Where can I run git if cmd doesn't work?

[S-Dafarra]

Apologies, I misunderstood the error message of #169 (comment)

The problem was not that git was not working. The problem was that the system did not go to the directory where you have osqp-eigen. Can you navigate to the folder where you have cloned osqp-eigen and do

git checkout master
git pull

?

[DRETQ]

Where i have cloned osqp-eigen is E:\LibraryVS15\osqp-eigen-master,isn't it? I don't know what you mean.

[S-Dafarra]

Where i have cloned osqp-eigen is E:\LibraryVS15\osqp-eigen-master,isn't it? I don't know what you mean.

Yes, please navigate to that folder and from within that folder execute the commands

git checkout master
git pull

[DRETQ]

@S-Dafarra Isn't that what I did before, with the same output as above?

No, if you look at #169 (comment) you can see that it remained in the folder C:\Windows\system32. I cannot copy the message since you attached (once more) an image

[traversaro]

In command prompt cd only works inside the active drive. So if the current working directory is C:\Windows\system32 if you do:

cd E:\LibraryVS15\osqp-eigen-master

the current working directory will remain in C:\Windows\system32, as the active drive remains C:.

To go to E:\LibraryVS15\osqp-eigen-master, you need to first make E: the active drive by typing E:, and then call cd E:\LibraryVS15\osqp-eigen-master, i.e. :

C:\Windows\system32>E:
E:>cd E:\LibraryVS15\osqp-eigen-master
E:\LibraryVS15\osqp-eigen-master>

See https://stackoverflow.com/questions/17753986/how-to-change-directory-using-windows-command-line or https://stackoverflow.com/questions/11065421/command-prompt-wont-change-directory-to-another-drive for more info.

[DRETQ]

@S-Dafarra What you mean is that I need to do git log -1, git checkout master, and git pull in osqp and osqp-eigen folders respectively, not in windows system32.

[DRETQ]

@traversaro Thanks for the reply, I've remembered

[S-Dafarra]

Where is the source code of osqp-eigen? Maybe E:/LibraryVS15/osqp-eigen-master/osqp-eigen-0.8.1?

[DRETQ]

@S-Dafarra

[S-Dafarra]

Neither E:/LibraryVS15/osqp-eigen-master/osqp-eigen-0.8.1 is a git repository. Where did you clone the repo?

[DRETQ]

@S-Dafarra When installing osqp-eigen, I didn't choose to use the git hub command directly with the osqp install, but instead downloaded the optional installer from the web.

Ok then use git clone to download the repo and try switching to the master branch.

[DRETQ]

@S-Dafarra This is a problem with debug x86 when debugging, it doesn't seem to be a problem if you use debug x64

[S-Dafarra]

Ah good catch. To be honest I don't think we test in CI x86 builds, let alone VS2015

[DRETQ]

@S-Dafarra Yes, I've asked before and no one has used it on VS2015. And have a new question, I have defined the sparse hessian matrix as a square matrix in my program, why does the output say this：
osqpeigen::data::sethessianmatrix the hessian matrix has to be a n*n size

[traversaro]

Hello @DRETQ, please:

• Use separate issues for each question (otherwise it is quite difficult for anyone to read issue if we mix different problems)
• If you have a problem on a code, please report the code you are compiling and running, and the complete error, ideally in text form instead of copy&pasting images.

Thanks!
