Fslbuild.py error:/usr/bin/env: ‘python3\r’: No such file or directory

josephzhou1 — Sun, 26 Dec 2021 07:56:33 GMT

I fellow fully the steps to build gtec-demo-framework but cant , error come out in the last step :

3.Build and the application.

FslBuild.py --Variants [WindowSystem=FB]

WindowSystem can bet set to either FB, Wayland, Wayland_IVI, X11 be sure to pick the right one. If the app doesn't require a WindowSystem the --Variants [WindowSystem=FB]can be omitted.

how can i build it pls ?

BTW how come NXP not have Xwayland Distro here , but yocto build got Xwayland very confuse leh??

also here you guys use -e not Distro , why not the same ???

Are you building on a supported Ubuntu version?

Does the ubuntu environment have python3 installed?

Best regards, René

josephzhou1 — Mon, 27 Dec 2021 01:25:16 GMT

YES i do use Ubuntu 20-04.

ubuntu no issues nor my yocto SDK toolchain .

my end all ok , i go google it i found out it is your NXP Fslbuild.py got issues it is DOS type of cos cnt use under Ubuntu / UNIX lah. see below:

dos is "\n\r"

unix is "\n" only left \r so error come out .

(Example :

$ cat test.py 
#!/usr/bin/env python3
print("ok")

$ ./test.py 
/usr/bin/env: ‘python3\r’: No such file or directory
$ dos2unix test.py 
dos2unix: converting file test.py to Unix format ...
$ ./test.py 
ok

)

i try it comments out line #1 Shebang line in your file Fslbuild.py , then ok but again line #32 got "\r" again and also many .py file all DOS TYPe in your release. i cnt do all manual jobs like this lah , see

the Shebang line

#!/usr/bin/env python3

There are no platform specific endings in our github release it works as any other github release.

1. the tar and zip release are encoded with unix line endings

2. the github checkout per default checks out with the platform specific endings (or whatever your configured it for).

So if you downloaded it from github via a clone its your git settings that are incorrect (or if you cloned on windows and tried to use it under unix).

I suggest you read this -> https://docs.github.com/en/get-started/getting-started-with-git/configuring-git-to-handle-line-endings

We have verified that cloning and building from github works properly on cleanly installed windows and ubuntu machines so it is something in your configuration that is incorrect. You also need to ensure you never clone on windows and try to use it on ubuntu or the other way around as you will encounter errors like the one you have.

hi all

I HAVE FELLOWED RENE'S WAY (git clone the repo in Ubuntu only ), to build it successfully and scp it binary to imx8 target , it is great , it can be run. thanks rene

but ,

it is still some warnings come out , it is not 100% see belows, please advices why it is happened and how to overcome it to make it 100%, i thanks AS NXP also wanto to be 100% rite?

thanks anyway.

The warnings are currently expected and can be safely ignored.

We will get around to removing them but we did review them and deemed them safe to ignore.
