[Feature Request] Alpine support

[ConYel]

relevant issue: LieberInstitute/megadepth#6

I am trying to build megadepth on alpine container in order to have a "slimmer" image in the end.
I get various issues from compiling.
the image currently:

FROM docker.io/rhub/r-minimal:4.4.1-patched as builder

RUN apk update
RUN apk add --no-cache --update-cache \
    --repository http://nl.alpinelinux.org/alpine/v3.20/main \
    autoconf=2.72-r0 \
    automake=1.16.5-r2 \
    bash tzdata libcurl git zlib gcc musl-dev xz-dev gcompat

RUN echo "America/Edmonton" > /etc/timezone
WORKDIR /home/hello
RUN git clone https://github.com/ChristopherWilks/megadepth.git
WORKDIR /home/hello/megadepth

CMD [ /bin/sh ]

Then I run inside the container :

 ./build_megadepth.sh
.
.
.
.

+ autoconf
+ make clean

Hi @ConYel,

I'd suggest it's better to just download a pre-compiled static version of megadepth into your container which I can compile pretty easily for the lastest 1.2.0 version---instead of you trying to compile it yourself, since that is far from easy (as you've found).

What architecture are you on (I'm assuming either x86_64 or aarch64, if it's something else I might have difficulty compiling for that)?

Chris

Dear @ChristopherWilks , thank you for your prompt reply and of course for the tool!

I understand your concerns but my point here is to manage to compile it in an alpine docker container.
I am working on reproducibility and afterwards I will try to make reproducible binaries.
Yes I am working on x86_64.
Is the htslib the main problem?
