we don't have openssl installed in our images, you'll have to install it yourself or use vendored

You can maybe use system packages using debian (ubuntu doesn't distribute mips anymore).

I'd recommend you to use the vendored feature

specifically for mips-unknown-linux-musl, I had to download openssl, compile it, and set OPENSSL_LIB_DIR/OPENSSL_INCLUDE_DIR properly for this to happen, as I could not apt install openssl-devel nor libssl-dev (not found)

I basically followed the instructions in the first answer here, changed as follows:

`
cd /tmp

apt update
apt install wget

wget https://www.openssl.org/source/openssl-1.1.1t.tar.gz
tar xzf openssl-1.1.1t.tar.gz
export MACHINE=mips
export ARCH=mips
export CC=mips-unknown-linux-musl-gcc
cd openssl-1.1.1t && ./config && make

cd $PROJECT_DIR

export OPENSSL_LIB_DIR=/tmp/openssl-1.1.1t/
export OPENSSL_INCLUDE_DIR=/tmp/openssl-1.1.1t/include

cargo build --target mips-unknown-linux-musl --release
`

Pasting the Dockerfile I used for a custom cross image

FROM  ghcr.io/cross-rs/mips-unknown-linux-musl:latest
## Base rust 'cross' image for compiling on mips-unknown-linux-musl (gl-inet)
ENV OPENSSL_V="1.1.1t"
ENV OPENSSL_LIB_DIR=/tmp/openssl-${OPENSSL_V}
ENV OPENSSL_INCLUDE_DIR=/tmp/openssl-${OPENSSL_V}/include

RUN set -o errexit \
    && apt-get update \
    && apt install --yes wget clang g++-multilib \
    && cd /tmp \
    && wget https://www.openssl.org/source/openssl-${OPENSSL_V}.tar.gz \
    && tar xzf openssl-${OPENSSL_V}.tar.gz \
    && export MACHINE=mips \
    && export ARCH=mips-linux-muslsf \
    && export CC=${ARCH}-gcc \
    && cd /tmp/openssl-${OPENSSL_V} \
    && ./config \
    && make

RUN export OPENSSL_V="1.1.1t" \
    && export OPENSSL_LIB_DIR=/tmp/openssl-${OPENSSL_V} \
    && export OPENSSL_DIR=/tmp/openssl-${OPENSSL_V} \
    && export OPENSSL_INCLUDE_DIR=/tmp/openssl-${OPENSSL_V}/include

Got this working and attached a working description

Checklist

Describe your issue

What target(s) are you cross-compiling for?

Which operating system is the host (e.g computer cross is on) running?

What architecture is the host?

What container engine is cross using?
