arduino-cli: not found. Sopine A64 on OpenWrt OS

[NamlaZz]

I am unable to install any version of arduino-cli beyond 0.5.0-showports.

This is what I get when installing through curl the latest version of arduino-cli. Note that /root/bin/ is already appended to my $PATH.
root@s200:~# curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh

sh: /root/bin/arduino-cli: not found

However when installing version 0.5.0-showports or older it works:
root@s200:~# curl -fsSL https://raw.githubusercontent.com/arduino/arduino-cli/master/install.sh | sh -s 0.5.0-showports

arduino-cli Version: 0.5.0-showports Commit: 3d7717e installed successfully in /root/bin

Version 0.5.0-showports does not contain all the functionalities that I need for the project, most importantly the serial monitor. Attached below are system information for my OS.

Linux version 5.10.96 (builder@buildhost) (aarch64-openwrt-linux-musl-gcc (OpenWrt GCC 11.2.0 r18729-8c1d5129ee) 11.2.0, GNU ld (GNU Binutils) 2.37)

Hi @NamlaZz. Thanks for your report.

What do you get if you run this command?:

ls /root/bin/arduino-cli

[NamlaZz]

Running this command after failure to install is shown as below:

sh: /root/bin/arduino-cli: not found
Failed to install arduino-cli
root@s200:~# ls /root/bin/arduino-cli
/root/bin/arduino-cli

I'm pretty sure the installation script is failing at this command:

arduino-cli/install.sh

Line 205 in 12d488f

APPLICATION_VERSION="$("$EFFECTIVE_BINDIR/$PROJECT_NAME" version)"

What do you get if you run this command?:

/root/bin/arduino-cli version

[NamlaZz]

this is what I get when I run the command:
root@s200:~# /root/bin/arduino-cli version
-ash: /root/bin/arduino-cli: not found

What shell are you using? Do you have a /tmp folder on your system?

I think the problem is the missing glibc in your OS (since it's built on musl)
AFAIK the cli shouldn't have any CGO dependency on Linux so, if compiled with CGO_ENABLED=0 it should also run on your setup.

Would you mind testing the attached binary? It's the cli compiled with GOOS=linux GOARCH=arm64 CGO_ENABLED=0 go build
arduino-cli-cgo-disabled.zip

For reference, this is the output on file on both binaries

file ./arduino-cli-official                     
./arduino-cli: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, Go BuildID=v0P18lFJNQ4WeE4mt508/fNlonX00LtFjhF7tzJe9/SC8S6mPmPVKw-PyFgZrm/GTK9qrY1RiFtclTFe8Ot, not stripped

So the difference is indeed statically linked vs dynamically linked

it's Almquist shell, I have /tmp folder

I SCPed the file into /root/bin and indeed it works, I tried running the below command to check the version.
root@s200:~# arduino-cli version
arduino-cli Version: 0.0.0-git Commit: Date:

A new release of Arduino CLI is available: 0.0.0-git → 0.21.1
https://arduino.github.io/arduino-cli/latest/installation/#latest-packages

although not indicated it appears that I have a working version of 0.20 or 0.21 of arduino-cli. What can I do to bypass this problem for future releases?

[facchinm]

My suggestion for the @arduino/team_tooling is to compile with CGO_ENABLED=0 for all the platform where it's possible (probably every platform except MacOS)
