Error while running raspi function to connect to external Raspberry Pi 3.

How can I solve the following issue? Thanks :)

Answer 1

[Carroll Guertin]

ssh or use command line in pi's desktop

Run these commands:

sudo apt-get update
sudo apt-get install libnanomsg-dev libasound2-dev

[Ahmed Bouzidi]

thanks man, this worked for me, ty :)

[francois crafford]

Thank you so much this also worked for me.

[Ege Gediksiz]

This also worked for me.

Answer 2

[afagh mohagheghi]

Same issue here, tried everything suggested, it did'nt work, any suggestions?

[Carroll Guertin]

Hi afagh,

What is the error message now?

Did the "nanomsg/nn.h" error go away?

Answer 3

[David]

Hi,

Did you solve the problem? I'm facing the same issue here. I have installed the required packages through MATLAB Support Package for Raspberry Pi Hardware. The set up seemed to be completed, but when I try to create de raspi object with raspi() I get the same error than you do.

[Carroll Guertin]

Hi David,

Did you run the "apt-get" commands that I posted in a previous comment?

Different error? Did the "nanomsg/nn.h" error go away?

If so, what is the error message now?

- Carroll

[David]

Hi Carroll,

Yup, I ran the commands and both packages are up-to-date. I do see the "nanomsg/nn.h" error.

I am using a Raspberry Pi 3 B+ with Raspbian Stretch and MATLAB-related packages installed with this. I use MATLAB R2018a.

This is the message error I get.

Thanks for your help!

i have same issue. can anyone help

Thanks in advance

[Carroll Guertin]

The apt-get commands had worked for me.

Have people run the "Hardware Setup" app?

That is suppose to install all necessary packages.

Hello guys, Did anybody solve this I have been trying for ages. Please write something here if you found a solution. I don't even have to know the solution. It is enough for me to know that there is a solution for this.

[Carroll Guertin]

Hi Osman, Have you tried the apt-get commands and/or the "Hardware Setup" app that I wrote about in other comments?

[Osman Ertunc]

Yes, I’ve tried it. It gives the same error. Is there any other solution that you could suggest. Genuinely, I am stuck. Also when I try with matlab raspbian image SD card keeps changing the partition. I can’t see what I wrote to SD card. I’ve formatted it in FAT32. But I can’t format it in FAT even with format applications. Currently, I am using 16gb raspberry manufactured SD Card. Any suggestion is fine please let me know!!
