Sharp: Build failing on Alpine Linux

[sabrehagen]

Hi,

Apologies for my lack of insight into why this is happening, all I can provide you is an error message, repro steps, and 'sharp isn't installing on alpine linux'.

The following commands produce the error message below. How can I begin to debug this further?

docker run -it alpine:edge /bin/ash

# inside container
apk add vips --update-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrusted
apk add nodejs python
npm install sharp

/ # npm install sharp

> [email protected] install /node_modules/sharp
> node-gyp rebuild

Hello, the version of vips in the Alpine "testing" repo is v8.3.1 but sharp v0.16.0 requires a minimum of v8.3.3. @wjordan is listed as the package maintainer so may be able to help.

[sabrehagen]

@wjordan would really love some help here :) moving to production in the next two days and I don't have the requisite skills to solve this one!

[wjordan]

Updated Vips to 8.3.3 in the PR linked above. While the merge is pending you can use the built version from my locally-hosted repo, your build steps should work for the most part:

apk add vips-dev --update-cache --repository http://wjordan-apk.s3.amazonaws.com/ --allow-untrusted
apk add python nodejs g++ make
npm install sharp

For production use to minimize the build size, you might want to install a pre-built node-sharp package (I have a PR for this at alpinelinux/aports#30). I haven't updated this to 0.16.0 yet though.

[sabrehagen]

Appreciate your work, I'll give it a go. Thanks!

[lovell]

libvips v8.3.3 is now available via apk, thanks @wjordan

I don't believe this problem should be closed. It's not a vips issue.

In the error log, you'll see

ERROR: musl libc (x86_64) requires manual installation - please see http://sharp.dimens.io/en/stable/install/
gyp: Call to 'LDD_VERSION="musl libc (x86_64)
Version 1.1.14
Dynamic Program Loader
Usage: ldd [options] [--] pathname" node -e "require('./binding').download_vips()"' returned exit status 1 while in binding.gyp. while trying to load binding.gyp
gyp ERR! configure error 
gyp ERR! stack Error: `gyp` failed with exit code: 1

Opening up binding.gyp you will eventually find the following command.

'download_vips': '<!(LDD_VERSION="<!(ldd --version 2>&1 || true)" node -e "require(\'./binding\').download_vips()")'

The pipe to true never succeeds so node-gyp throws us an exit 1.

db02d024bb15:~# ldd --version 2>&1
musl libc (x86_64)
Version 1.1.15
Dynamic Program Loader
Usage: ldd [options] [--] pathname
db02d024bb15:~# echo $?

db02d024bb15:~# ldd --version 2>&1 || true
musl libc (x86_64)
Version 1.1.15
Dynamic Program Loader
Usage: ldd [options] [--] pathname
db02d024bb15:~# echo $?
0

As an example, removing the LDD_VERSION= var check portion and then trying to npm install again will allow you to get further.

@pporada-gl the salient message is ERROR: musl libc (x86_64) requires manual installation. Alpine Linux currently provides libvips v8.3.3 via apk - http://pkgs.alpinelinux.org/packages?name=vips

[pporada-gl]

@lovell We have vips in our container though.

db02d024bb15:~# apk info vips
vips-8.3.3-r0 description:
A fast image processing library with low memory needs

vips-8.3.3-r0 webpage:
http://www.vips.ecs.soton.ac.uk/

vips-8.3.3-r0 installed size:
2093056

This is not a vips issue. I believe it's a node-gyp shell out issue.

@pporada-gl Which version of sharp are you using?

[pporada-gl]

I have forked from master earlier this morning and am on v0.17.0. I get failures later on during the build about vips 8.4.x, but can at least get past the ldd problem on my fork.

[lovell]

@pporada-gl The forthcoming, yet-to-be-published v0.17.0 of sharp will require libvips v8.4.2+ - see https://github.com/lovell/sharp/blob/master/package.json#L88
