I have been running a gcc compiler for an old tool chain, m68k-elf on an Ubuntu VM for years. With wsl2, I thought I would try to go native. I installed binutils, make, and copied all the installation directories over from a working image.
When I run make, it throws a syntax error. Its a working project so it's not that. It's something else. I'm not into linux so I cant help but to say I will try to follow steps if you can go kinda slow.

[therealkenc]

make is not a repro. You could in the hypothetical entertain posting repro steps leading to your error, but the probability of arriving at a syscall diverge here is.... low.

[TheRealBard]

I dont follow. sycall diverge?

[therealkenc]

sycall diverge?

A problem with WSL1's implementation of the Linux kernel. As opposed to a problem in userspace.

[therealkenc]

I might be able to guess without a repro. Post the result of:

$ file /usr/local/m68k-elf/bin/gcc

[TheRealBard]

file /usr/local/m68k-elf/bin/gcc
/usr/local/m68k-elf/bin/gcc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.2.5, not stripped

I installed the toolchain with guidance from a guy who knows it real well. I installed binutils, then make, then copied the tree of files into place that he had prepared off his own machine. I have it in a .tgz file, but it's like 9mb. not sure if a link to that would be useful. Then try to make a known good project.

[therealkenc]

/usr/local/m68k-elf/bin/gcc: ELF 32-bit LSB executable

That was the guess. This is actually a diverge of sorts; 32-bit binaries are not supported on WSL1. Happily you are on 19041 aka 2004 aka 20H1: you want WSL2.

/dupe #2468 dating back to #228.

Hi! We've identified this issue as a duplicate of another one that already exists in this repository. This specific instance is being closed in favor of tracking the concern over on the referenced thread.

Thanks for your report!

[TheRealBard]

ah.. i had no idea I was on 1.. Strange, I thought it just came with 2004.. they should mark it or something.

[therealkenc]

they should mark it or something

wsl.exe -l -v
