Cross compile a aarch64-linux-musl binary linking failed with `cannot find -lgc`

Help & Support

I use following command cross compile a aarch64 linux musl binary in AMD64 platform.

mkdir -p bin &&     shards build --production --release --no-debug     --error-trace --static --stats --time     -Dstrict_multi_assign -Dno_number_autocast -Duse_pcre2 -Dno_restrictions_augmenter     --cross-compile --target=aarch64-linux-musl |tail -1 > bin/app.sh

It works, the content of generated file bin/app.sh is:

cc /app/bin/hello_world.o -o /app/bin/hello_world -rdynamic -static -L/usr/bin/../lib/crystal -lpcre2-8 -lgc -levent

When it run on a linux/arm64 container, get following error.

0.151 /usr/lib/gcc/aarch64-alpine-linux-musl/13.2.1/../../../../aarch64-alpine-linux-musl/bin/ld: cannot find -lgc: No such file or directory
0.208 collect2: error: ld returned 1 exit status

I don’t know why it went wrong, musl-dev was installed before cross linking.

RUN --mount=type=cache,target=/var/cache/apk \
    set -ux; \
    apk add \
    --update \
    git \
    pcre2-dev \
    libevent-static \
    musl-dev g++ make automake libtool autoconf curl \
    ;

Any idea?

Oops, missing gc-dev, it is one of crystal dependency.
