Building micro on Ubuntu/RISCV64

[phpeterson-usf]

I'm trying to cross compile micro, and I see the recent change in the Makefile. However when I try to build like this (host: darwin/arm64, target: linux/riscv64): % CGO_ENABLED=0 GOOS=linux GOARCH=riscv64 make build

I get these results.

GOOS=darwin GOARCH=arm64 go generate ./runtime
go build -trimpath -ldflags "-s -w -X github.com/zyedidia/micro/v2/internal/util.Version=2.0.11-dev.66 -X github.com/zyedidia/micro/v2/internal/util.CommitHash=9ce469f3 -X 'github.com/zyedidia/micro/v2/internal/util.CompileDate=July 15, 2022' -linkmode external -extldflags -Wl,-sectcreate,__TEXT,__info_plist,/tmp/micro-info.plist" ./cmd/micro

If you're wondering why I don't just compile micro on the linux/riscv64 VM, the reason is that apt install golang-go on Ubuntu 20.0.4.4 (RISCV64) installs go 1.14 - too old to build micro.

I'd love to get any advice for getting micro going on my Ubuntu RISCV64 system.

Thanks for reporting this, this is an issue with cross compilation specifically from mac. The builder tries to embed some additional information in binaries built for mac, but it was doing the detection based on the host OS not the target. I have pushed a new commit that fixes the build system, so you should be able to cross compile from mac now.

Thank you!
