Cross compiling failed. · Issue #372 · mattn/go-sqlite3

原因

mattn/go-sqlite3 を含めbuildしたが特にエラーはなく。しかし実行すると下記の一文が。

Binary was compiled with 'CGO_ENABLED=0', go-sqlite3 requires cgo to work. This is a stub

buildするときに、 CGO_ENABLED=1 を加えてみると。

$ env CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build

brew install go にオプションで、 --with-cc-all 、 --with-cc-common してもオプションが不正となる。
