Cross-compiling fails from 64-bit linux to arm linux

[nuclearsandwich]

I get the following output when trying to create a buffalo build for another target using

env GOOS=linux GOARCH=arm GOARM=7 buffalo build

I'm pretty green so it could very well be user error with the compiler toolchain but I also don't know how to get more info beyond Error: exit status 2.

Thanks!

I get the same error when attempting to build a linux binary from a Mac

I haven't had a chance to run this yet. I build Linux binaries no problem, but not arm. My gut says it's an arm/SQLite issue judging by the output. I'm traveling so I haven't been able to run the exact same command yet. I'll post when I do.

Do Linux binaries build for you, from a Mac?

[markbates]

Yes, but I haven't tried arm yet. I think it's a problem with arm and SQLite. But not sure.

[markbates]

I've worked the maintainer of the sqlite driver, and helped him fix the build issues.

See mattn/go-sqlite3#374 and mattn/go-sqlite3#372

If you do a go get -u github.com/mattn/go-sqlite3 this issue should be fixed.

If someone else could test, I've tested locally, but I don't like to close until a 3rd party has confirmed.

Thanks! That fixed my problem building linux binaries from the Mac

[markbates]

Woot!! Yay!!

Yes, but I haven't tried arm yet. I think it's a problem with arm and SQLite. But not sure.

I did some additional digging last night and found the same thing, I was lacking gcc compilers for my target ARM platform, rectifying that fixed the build issue, which I think means the overall issue here is closed, but I wonder if it's possible to get better feedback from buffalo build as I figured this out by running

env GOARM=7 GOARCH=arm GOOS=linux go build
# github.com/mattn/go-sqlite3
../github.com/mattn/go-sqlite3/tracecallback_noimpl.go:39: undefined: Error

Then guessing from there.

As a secondary issue, when I got the built binary to my target platform (Raspberry Pi 3) it couldn't find the assets. Some poking around after that revealed that the initial go get -u github.com/gobuffalo/buffalo/buffalo didn't install the rice command line tool.
