<undefined reference> problem while compiling a binary for Arm from Linux

[cheer-Yuan]

Hello,

I am trying to compile a program of ARM with tinygo from Linux, when I enter the following command :

GOARCH=arm tinygo build -o <OutputName> ./main.go

I got :

/usr/lib/gcc-cross/arm-linux-gnueabihf/9/../../../../arm-linux-gnueabihf/bin/ld: /tmp/tinygo859602615/main.o: in function `syscall.Seek':
/usr/local/go/src/syscall/syscall_linux_arm.go:60: undefined reference to `syscall.seek'

The relevant codes indicated here above are :

// Underlying system call writes to newoffset via pointer.
// Implemented in assembly to avoid allocation.
func seek(fd int, offset int64, whence int) (newoffset int64, err Errno)

func Seek(fd int, offset int64, whence int) (newoffset int64, err error) {
	newoffset, errno := seek(fd, offset, whence)
	if errno != 0 {
		return 0, errno
	}
	return newoffset, nil
}

I have just use

sudo apt-get install arm-linux-gnueabihf

to install this package.

However,

GOARCH=arm go build -o <OutputName> ./main.go

works without any problem.
Using CGO_ENABLED="0" flag doesn't change anything.
I have searched on the Internet and found no similar issues. Thank you for any possible information.

Environment :

Linux 5.4.0-73-generic #82-Ubuntu SMP Wed Apr 14 17:39:42 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
go version go1.16.3 linux/amd64
CGO_ENABLED="1"

Also seems to affect i386. See log
https://github.com/tinygo-org/tinygo/runs/4687146838?check_suite_focus=true
from #2457

I have a local branch to implement Go assembly. It's not complete (only works on amd64 and arm64 now) but once finished that branch should fix this issue.

[dkegel-fastly]

May be fixed already by #2571 in 0.22?

Please try 0.22 or dev and see if that works better.

This is fixed now, see #2571.
