How to build for arm64

[cwegener]

I've tried to cross-compile for GOARCH=arm64 but the resulting build fails to execute on arm64 when using dynamic CGO linking due to GLIBC version mismatches of my build host and the target host.

And with static CC compiler flags, the resulting binary segfaults with

usql: dl-call-libc-early-init.c:37: _dl_call_libc_early_init: Assertion `sym != NULL' failed.
SIGABRT: abort
PC=0xa60894 m=0 sigcode=18446744073709551610
signal arrived during cgo execution

Is there a supported cross-compile procedure?

NOTE: The target platform is Ubuntu 20.04 on arm64 (Neoverse / Graviton)

Update - building natively with go build on Ubuntu 20.04 arm64 results in a perfectly usable binary.

Great to know you were able to build it. While Go is pretty good at cross-compilation, one of the main drivers that are enabled by default (sqlite3) requires CGO. As such, cross-compilation is probably non-trivial if building the default set of drivers.

However, this was able to work:

ken@ken-desktop:~/src/go/src/github.com/xo/usql$ GOOS=linux GOARCH=arm64 CGO_ENABLED=0 go build -tags 'most no_sqlite3 no_adodb'
ken@ken-desktop:~/src/go/src/github.com/xo/usql$ file usql
