Pgloader: Unable to build pgloader on Alpine

[aa8y]

I am trying to build a Docker image with pgloader on Alpine. But it fails with the error:
While evaluating the form starting at line 21, column 0 Fatal EXTENSION-FAILURE: Don't know how to REQUIRE SB-BSD-SOCKETS. See also: The SBCL Manual, Variable *MODULE-PROVIDER-FUNCTIONS* The SBCL Manual, Function REQUIRE of #P"/pgloader-bundle-3.4.1/dumper-2SKVI5f7.lisp":make: *** [Makefile:47: bin/pgloader] Error 1 The command '/bin/sh -c make' returned a non-zero code: 2

The contents of my `Dockerfile` are:

FROM alpine:3.5

RUN echo '@testing http://nl.alpinelinux.org/alpine/edge/testing' >> /etc/apk/repositories && \
apk add --update \
bash \
ca-certificates \
g++ \
make \
sbcl@testing \
wget && \
rm -rf /var/cache/apk/*

RUN wget https://github.com/dimitri/pgloader/releases/download/v3.4.1/pgloader-bundle-3.4.1.tgz && \
tar -xvzf pgloader-bundle-3.4.1.tgz
WORKDIR pgloader-bundle-3.4.1
RUN make

I don't always build linux packages. So it's possible I am doing something wrong. I just don't know what is. I also tried to use `ccl` and modeled it around [this Dockerfile](https://hub.docker.com/r/dimitri/pgloader/~/dockerfile/) but based it on `alpine` instead. It kept failing with:
```../pmcl-kernel.c:39:20: fatal error: mcheck.h: No such file or directory
 #include <mcheck.h>
                    ^
compilation terminated.

This probably because it uses musl. But the steps I mentioned in my Dockerfile here, just use sbcl.

Which version of SBCL does Alpine provide here?

[aa8y]

@dimitri This is what I get:

bash-4.3# sbcl --version
SBCL 49115.-ca92cb7079

[dimitri]

Well that version number isn't the SBCL version number. I don't know what Alpine is doing here. When looking at https://pkgs.alpinelinux.org/package/edge/testing/x86_64/sbcl I got it you could have 1.3.16. The -r0 is strange, tho. Anyway it should provide SB-BSD-SOCKETS, which is an SBCL provided system.

Why do you want to build with Alpine?

[aa8y]

I've got another image which is based on postgres:alpine to keep it small. I wanted to use pgloader on it. So I made a PoC to see if I can get it running on Alpine. Are you able to reproduce the issue by building an image from the Dockerfile snippet I shared?

[dimitri]

I didn't try. To be honest given the errors you have, I'm not that interested :/

[aa8y]

Well, I could use your help. But if you can't that's okay. You can close the ticket.

sbcl on Alpine was broken, I've fixed it today and it builds pgloader now.
