NCSDK make install: "Error in line 170"

[idata]

I am starting a new thread for this, because I was able to collect additional information and pinpoint the error to a specific line of code in the bash script.

After installing Raspbian Stretch on a Raspberry Pi 3B, I clone the NCSDK repository and run make install.

It does not matter if I run it normally or using sudo, I always get the same error: Error in line 170.By stopping script execution and adding some debug echoes, I was able to verify that indeed the following line of code is responsible for the error:PREV_INSTALL_INFO='$SUDO_PREFIX find /opt /home -name $INSTALL_INFO_FILENAME -print 2> /dev/null'

Running something like

sudo find /opt /home -name .ncsdk_install.info -print 2> /dev/nullin the console does not generate any kind of error.

Deleting this line and the following if-fi statement before continuing execution will make the script run normally until it is finished, so in my eyes this is an actual bug, but I wouldn't know where to add a bug report.

I'm looking forward to any kind of help.

Note: Please keep in mind I only have little experience with Linux.

OK, Let's calm down and step by step.

I think that if you are logged in as "pi" for general users it will work.

I installed it over 5 times and I never failed, so I think it's not a NCSDK's bug.Execute the following command at the terminal.What is displayed on ???

$ whoami ??? <--- What is displayed?

$ echo $EUID ??? <--- What is displayed?

And, Execute the following command at the terminal.

What is displayed on ???

$ sudo -V

Point is an if statement of "/opt/movidius/NCSDK/install-ncsdk.sh" line 117.

The "if" statement should be TRUE.

When it is 「$EUID = 0」<--- Already super user

other than that 「$EUID != 0」 <--- General user or Other

[idata]

What does this tell me?

By the way, it's line 170, not 117.

@MarkusA380

Thank you for your reply.

By the way, it's line 170, not 117.

Yes, I know. The 170th line is a script that expects "SUDO_PREFIX =" sudo "" in line 118 to be stored.

PREV_INSTALL_INFO=`$SUDO_PREFIX find /opt /home -name $INSTALL_INFO_FILENAME -print 2> /dev/null`

$INSTALL_INFO_FILENAME /opt/movidius/.ncsdk_install.info

ncsdk_path=/opt/movidius ncs_lib_path=/usr/local/lib ncs_inc_path=/usr/local/include ncs_bin_path=/usr/local/bin

I checked whether the parameters were assigned properly or not.

Umm…It seems there is no problem.

I'm sorry.A good idea does not come out soon.

[idata]

Thank you. I hope someone will find a fix.

@PINTO, @Tome_at_Intel , because I use this Raspberry for nothing else, I could offer a RDP connection so one of you or someone else could see the problem live and do some research on why it happens. I would reset the device to a fresh install and exactly to the point where the error occurs.

@MarkusA380

Can I check only one at the last if allowed.

Could you tell us the result of the command below?

$ echo $LANG

[idata]

@PINTO Of course, today I fubar'd my Raspbian-installation (partially on purpose), so it will take about one more day until I have reset the installation and test it. At that point I can provide ip and login credentials for XRDP, too.

Hello,

I'm just getting started. I've cloned the latest and end up with the same message on Ubuntu 16.04.

Quite annoying right out of the gate with this:

Installation failed. Error on line 170

[idata]

The NCSDK git repo 'make install' pulls down a file to /opt/movidius and runs an installer there. I dug into the installer found at /opt/movidius/NCSDK/install-ncsdk.sh

Line 170 dealt with previous installs of the SDK which I didn't have, so I forged ahead with commenting this chunk out.

It at least got through the installation process. I haven't tried examples yet to prove it worked.

I got exactly the same error when installing on RPI3B+

Can anyone help?

Hi @xou822

You might have other _unsuccessful_ installations of the NCSDK on the Pi - is this the first time you've attempted to install the NCSDK?

Best Regards,

I also encountered this problem while installing NCSDK.

If you execute the line as it is written, 2> /dev/null/ will suppress any errors that arise (by sending them to /dev/null). Try executing the line of code responsible for the error (i.e. line 170 in /opt/movidius/NCSDK/install-ncsdk.sh) but without redirecting stderr to /dev/null.

sudo find /opt /home -name .ncsdk_install.info -print

Examine any errors which arise from executing this command and resolve them.

In my case it was a corrupted directory path in /home which was causing the find command to give an "Input/output error". I rebooted (which somehow fixed the corrupted path) and removed the directory which was causing the issue (although I might not have needed to, I didn't think to test it). Then I executed sudo make install again in the ncsdk directory cloned from GitHub and install was successful.

Hope this helps
