Subject: Re: Pre-compiled static go binary fails with "undefined symbol
'syscall'"
OpenBSD recently changed access to its syscalls.
The change which allows upstream Go to build working executables
for current OpenBSD was committed on May 4th.
https://github.com/golang/go/commit/8841f50d98b224ecf5ee27d9b7e6f18ad2c98e46
The kitty binary was built by Go version 1.22.4.
$ strings kitten-openbsd-amd64 | grep go1
...
go1.22.4
Go 1.22.4 was released June 4th.
https://go.dev/doc/devel/release#go1.22.0
It isn't an issue with the Go version used to compile.
The change was upstreamed two months ago, and the Go version used
was released one month ago.
It's an issue with kitty itself.
$ git clone https://github.com/kovidgoyal/kitty .
$ grep -r syscall *
...
kittens/transfer/receive.go:func syscall_mode(i os.FileMode) (o uint32) {
kittens/transfer/receive.go: if err :=
unix.Fchmodat(unix.AT_FDCWD, self.expanded_local_path,
syscall_mode(self.permissions), unix.AT_SYMLINK_NOFOLLOW); err == nil ||
!(errors.Is(err, unix.EINTR) || errors.Is(err, unix.EAGAIN)) {
kittens/transfer/send.go: "syscall"
kittens/transfer/send.go: stat, ok := stat_result.Sys().(*syscall.Stat_t)
kittens/transfer/send.go: stat, ok :=
st.Sys().(*syscall.Stat_t)
...
Kitty uses syscalls in a way which OpenBSD no longer supports.
Send the maintainer of Kitty to look at this code:
https://github.com/golang/go/blob/master/src/syscall/syscall_openbsd_libc.go#L19
If they're willing to do the work, they'll have enough information
to figure out how to fix the software.
