在几篇博文（this和this）之后，我试图从RPi 3上的源代码构建CockroachDB。
我的RaspberryPi设置：
- 操作系统：2018-06-27-raspbian-stretch
- CPU：ARMv7版本4（v71）
- Mem：1G + SWAP：1.5G
- Go版本：go1.11 linux / arm
在“制作”时，我修复了一些有关第三方库的错误，但现在我陷入了困境：
pi@raspberrypi:~/work/go/src/github.com/cockroachdb/cockroach $ make build TAGS='stdmalloc' -j2
GOPATH set to /home/pi/work/go

任何想法可能有什么问题吗？
