Compile to arm cpu error

[dylanlyu]

C source files not allowed when not using cgo or SWIG: sqlite3-binding.c

i try export CGO_ENABLED=1 but

runtime/cgo

clang: error: argument unused during compilation: '-mno-thumb'

What ideas can be compile successfully???

👍 on OSX (go version go1.5.2 darwin/amd64) building for Linux

Hi.i got this problem too.
Did you fix this problem finally?How?

[mattn]

you compiler have --build-id flag?

[ZhouLiHai]

CC=arm-none-linux-gnueabi-gcc
Finally, Use this flag to setup you own compiler, not use Clang.

[mattn]

go-sqlite3 doesn't require --build-id flag but seems go require it.

In case someone else stumbles on this as I did here is the complete info:

• to cross compile you need the cross compiler. I am targeting hard float so mine is arm-linux-gnueabihf-gcc/arm-linux-gnueabihf-g++ . Get it installed - for linux there are official packages, for mac search around there are plenty of resources on how to get/install the gcc toolchain targeting arm
• add the crosscompiler toolchain to the path
• to build your go program you need to use the above compiler. Just run:

env CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ \
    CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 \
    go build -v main.go

Chipping in, for those targeting the arm64 arch out of linux distro. Here are the commands:

sudo apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu

env CC=aarch64-linux-gnu-gcc CXX=aarch64-linux-gnu-g++ CGO_ENABLED=1 GOOS=linux GOARCH=arm64 go build -v -o arm64

FWIW I have a script that compiles rqlite for a bunch of CPU architectures here: https://github.com/rqlite/rqlite/blob/master/scripts/package.sh

These are the needed cross-compilers for Linux:
