Unable to compile on Alpine linux

[b-i-t-n]

I am building XMRig in a Alpine Docker container.
I have had a quick look around on how to fix this but I am not a c++ dev.

It could be because Alpine linux does not use glibc so in most cases it is treated like linux but should be treated like osx or freebsd.

Can you provide some instructions how setup developer environment, install compiler, cmake, libuv on Alpine Linux. It can speed up process because I was never work with that Linux.
Thank you.

What I have done to install xmrig on Alpine linux manually

# apk add openssl-dev curl-dev git cmake libuv-dev build-base
# git clone https://github.com/xmrig/xmrig
# cd xmrig
# mkdir build
# cmake -DCMAKE_BUILD_TYPE=Release .
# make

To use the Dockerfile copy or download the following and run docker build --rm . in the same folder.

FROM  alpine:latest
RUN   adduser -S -D -H -h /xmrig miner
RUN   apk --no-cache upgrade && \
      apk --no-cache add \
        openssl-dev \
        curl-dev \
        git \
        cmake \
        libuv-dev \
        build-base && \
      git clone https://github.com/xmrig/xmrig && \
      cd xmrig && \
      mkdir build && \
      cmake -DCMAKE_BUILD_TYPE=Release . && \
      make && \
      apk del \
        build-base \
        cmake \
        git
USER miner
WORKDIR    /xmrig
ENTRYPOINT ["./xmrig"]

I probably do not need some of the packages as you do not support TLS or HTTP.

[xmrig]

Yes openssl-dev and curl-dev not required. Okay I will check it later.
Thank you.

I fixed it, just one include was missing.
