Cannot find value HOST_TAG in this scope

[justinmoon]

I'm on Arch Linux.

$ docker run -e PKG_CONFIG_ALLOW_CROSS=1 --rm -v "$(pwd):/root/src" \
   -w /root/src philipalldredge/cargo-apk cargo apk build

...

Without PKG_CONFIG_ALLOW_CROSS I was getting openssl errors.

Seems like the cfg statements aren't getting hit properly?

What's weird is that when I run this program inside the same docker container it outputs "You are running linux".

sudo docker run --rm -v "$(pwd):/root/src"    -w /root/src philipalldredge/cargo-apk cargo run
