dos2unix fails to change permissions when creating project from template

[juschri]

Hello, I have searched all over for an answer to my problem, and while I've found similar questions none of the answers have worked. I have followed the instructions in "The Nios II Embedded "Hello World" Lab: For the DE10-LiteDevelopment Kit" successfully up to the point where you create a new project in Nios II - Eclipse.

When I fill in the wizard and press Finish I get an error popup that says Failed to execute: wsl dos2unix create-this-bsp; ./create-this-bsp --cpu-name cpu --no-make

I also see the following message printed in the eclipse console window:

dos2unix: Failed to change the permissions of temporary output file ./d2utmpfnPN2u: Operation not permitted

I've tried launching eclipse from the Nios II command shell in several ways.

1. Running Nios II Command Shell.bat and executing
   • ./eclipse-nios2.exe
2. Running Nios II Command Shell.bat and executing
   • sudo ./eclipse-nios2.exe
3. Running Nios II Command Shell.bat as Administrator and executing
   • ./eclipse-nios2.exe
4. Running Nios II Command Shell.bat as Administrator and executing
   • sudo ./eclipse-nios2.exe

I tried playing around with using elevated command shell and elevated eclipse-nios2 because of the permissions message as well as an answer that said to launch eclipse from the Nios II Command Shell.

I've also made sure to apt install wsl, dos2unix, and make.

It might also be important to know that I am using Quartus Prime Lite v20.1.0 Build 711, and it's installed in C:\intelFPGA_lite\20.1

I also followed the instructions here

to install eclipse in the nios2eds/bin directory

Hi Eliath,

I see it has been 2 months since you replied to Justin's question but I don't see a solution.  Have you found one? I have this issue with Quartus lite v20.

I also ran into this problem. I did some debugging and the problem is that the dos2unix command tries to change the UNIX filesystem permissions of the temporary file it creates; this fails for me in WSL.

You need to tell WSL that it should allow these kinds of operations on the filesystem. You can do this as follows:

1. Start your Ubuntu 18.04 LTS prompt
2. Create/edit a file '/etc/wsl.conf'
3. Add the following to '/etc/wsl.conf':

   [automount]
   options = "metadata"

4. Save the file.
5. Reboot your computer.

I have no idea why this works for some people but not others, but this worked for me and fixed the dos2unix permissions error; at which points I was able to create the BSP and everything else in Nios II EDS worked fine.

Can you please provide how you did it? Is it in the command line? I can't seem to find anything

@NickWilliams solution worked for me. I followed the instructions on

https://ajeet.dev/how-to-use-windows-subsystem-for-linux/

to create the wsl.conf file. The exact steps I took were:

From within Ubuntu 18.04 LTS (which I already had installed for Windows Subsystem for Linux) I executed the command

explorer.exe .

In the explorer window that opened I went up 2 directories to Ubuntu-18.04

Next I opened the etc directory and created a new file titled "wsl.conf"

Next I opened this with a text editor and edited it to say

[automount]
options = "metadata"

as per @NickWilliams  suggestion.

I saved this file, then restarted my computer.

After restart I reopened my project in quartus, used the tools menu to open "Nios II Software Build Tools for Eclipse" Then following the instructions in the lab tutorial Eclipse was finally able to create my project without errors.

Hi @juschri,

The link you provided to create the file lead me to spam webpage (I think).

Could you explain more how exactly you entered the directory "/etc/" ?

this one >> "In the explorer window that opened I went up 2 directories to Ubuntu-18.04".

Thank you,

[juschri]

Hello,

I don't know why that link doesn't work anymore. I don't know how to find the page I referenced anymore.

This link explains how to do it though.

https://www.howtogeek.com/426749/how-to-access-your-linux-wsl-files-in-windows-10/

Inside WSL if you execute the command "explorer.exe ." it will open explorer in the current directory which is your WSL directory. Make sure you don't leave out the space and the period.

From there all you have to do is use the up arrow in the top left corner of the explorer window to reach the root directory and then you can enter the /etc directory.

Once there if you right click in the window you can create a new file.

name it "wsl.conf"

and follow the rest of the instructions above.

I don't know that it will help but my Eclipse build template command started working after I noticed the last line of text above the prompt after running the command "sudo apt update" in the Ubuntu command shell, the first of 4 command lines found in the "Intel FPGA Software Installation and Licensing" guide section 2.3.1.  The text referred to items that needed to be "Upgraded"  The command "sudo apt upgrade" worked for me.  I then re-ran the remaining three command lines and looked for anything else that needed to be upgraded.  There were none.  After that I was suddenly able to create Eclipse project templates, but I had tried everything else I could find before that point and the process woudl fail with the error message failed to execute dos2unix.

Hope it helps you.
