I have to compile a Go service for Ubuntu ARM-v7
When I compile it with
GOARCH=arm GOARM=7 go build -v -o release/edge_to_bc -ldflags '-s -w -extldflags "-static"' ./...
I get:
gitlab.com/company/edge_to_bc/vendor/github.com/hyperledger/fabric/bccsp/pkcs11

How should I fix it ?
Go-sqlite3 is cgo package.
If you want to build your app using go-sqlite3, you need gcc.
However, after you have built and installed go-sqlite3 with go install github.com/mattn/go-sqlite3 (which requires gcc), you can build your app without relying on gcc in future.
Important: because this is a CGO enabled package you are required to set the environment variable CGO_ENABLED=1 and have a gcc compile present within your path.
Cross compiling from Ubuntu to ARM7:
sudo apt install \
libc6-armel-cross \
libc6-dev-armel-cross \
binutils-arm-linux-gnueabi \
libncurses5-dev \
gcc-arm-linux-gnueabihf
env CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ \
CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7 \
go build -v
Using a docker image:
# Install docker
$ curl -fsSL https://get.docker.com -o get-docker.sh | sudo sh -
$ sudo usermod -aG docker your-user
# Go to your project folder
$ cd your-project-folder
# Compile
$ docker run --rm \
-v /tmp/.docker/go:/go \
-v /tmp/.docker/go-build:/root/.cache/go-build \
-v $PWD:$PWD \
-w $PWD \
filipeandre/go-compiler-to-arm7:1.12 \
go build -v
