How Do I Fix Compiling Errors With Some Crates?

[sansjack02]

For Example: error: failed to run custom build command for rust-crypto v0.2.36 Internal error occurred: Failed to find tool. Is clang-cl --target=x86_64-pc-windows-msvc installed? This is my rustup install:

RUN rustup default nightly && \
    rustup target add x86_64-pc-windows-msvc && \
    rustup component add llvm-tools-preview && \
    rustup toolchain install nightly && \
    rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu && \
    rustup target add x86_64-unknown-linux-musl

Is there something i need to install / edit in the docker file, i am using a fork of this docker file, so this shouldn't be an issues installing stuff. i have tried: RUN apt-get install musl-tools -y RUN apt-get install -y clang-tools but still no luck.
