My pc:
Linux 3.4.113-sun8i #4 SMP PREEMPT Wed Nov 22 13:45:28 CET 2017 armv7l GNU/Linux

[SteveL-MSFT]

@wojtulab what OS are you using with the arm32 build? Currently only Raspbian Stretch is supported.

[wojtulab]

oh, ok... its Armbian based on Debian (jessie):
ARMBIAN 5.36 user-built Debian GNU/Linux 8 (jessie) 3.4.113-sun8i

[SteveL-MSFT]

Unfortunately we are only currently support Raspbian Stretch. Maybe we can look into this post 6.0.0

Same here also fails on 6.1.0 Preview 2
But i tried it on a Xiamo Mi Vacuum, so no surprise.

@dantraMSFT should we consider just outputting a warning if Logging can't be enabled?

Still trying to wrap my head around it...

strace reveals, pwsh is reading the library:

open("/mnt/data/powershell/6.0.2/libpsl-native.so", O_RDONLY|O_CLOEXEC) = 56
read(56, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\4\27\0\0004\0\0\0"..., 512) = 512
read(56, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1480) = 1480

close(56)                               = 0
open("/mnt/data/powershell/6.0.2/libpsl-native.so", O_RDONLY|O_CLOEXEC) = 56
read(56, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\4\27\0\0004\0\0\0"..., 512) = 512

read(56, "A0\0\0\0aeabi\0\1&\0\0\0\0057-A\0\6\n\7A\10\1\t\2\n\3\22"..., 49) = 49
close(56)                               = 0
open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 56
close(56)                               = 0
open("/mnt/data/powershell/6.0.2/libpsl-native.so", O_RDONLY|O_CLOEXEC) = 56
read(56, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0(\0\1\0\0\0\4\27\0\0004\0\0\0"..., 512) = 512
read(56, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 1480) = 1480
read(56, "A0\0\0\0aeabi\0\1&\0\0\0\0057-A\0\6\n\7A\10\1\t\2\n\3\22"..., 49) = 49
close(56)  

So I guess it's more a "can't load the library" issue, and the "file not found" is misleading...
I also tried to add the pwsh directory to my ldconfig without success.

@SteveL-MSFT: Yes, we should, either a warning or error record. I created https://github.com/PowerShell/PowerShell/issues/6858 for this.

[iSazonov]

If I understand correctly this library (psl-native) was needed because of the limitations of .Net Core 1.0. Now we are on .Net Core 2.1 and maybe could review the code and could migrate to C#.

[SteveL-MSFT]

@iSazonov I agree that we should review whether this library is still needed
