lwip install fails

[IlyaSemenov]

I realise that this project is most probably abandoned, but in any case I'll leave the results of my investigation.

The thumbnail server won't compile in Alpine Linux 3.6 (probably other modern Linuxes as well).

Steps to reproduce:

docker run --rm -it alpine:3.6 sh

then inside the container:

apk add --no-cache \
        bash \
        build-base \
        git \
        freetype-dev libjpeg-turbo-dev openjpeg-dev zlib-dev  libpng-dev \
        nodejs nodejs-npm python
git clone https://github.com/chrisben/image-thumb.git
cd image-thumb
npm install

this will fail when compiling lwip with a zillion errors:

In file included from ../src/decoder/decoder.h:13:0,
                 from ../src/decoder/init.cpp:1:
../../nan/nan.h: At global scope:

../../nan/nan.h:590:7: error: 'GCEpilogueCallback' is not a member of 'v8::Isolate'
       v8::Isolate::GCEpilogueCallback callback
       ^~

Manually upgrading lwip with npm i lwip@latest will also fail:

In file included from ../src/lib/png/png.c:14:0:
../src/lib/png/pngpriv.h:805:4: error: #error ZLIB_VERNUM != PNG_ZLIB_VERNUM "-I (include path) error: see the notes in pngpriv.h"
 #  error ZLIB_VERNUM != PNG_ZLIB_VERNUM \
    ^~~~~
make: *** [lwip_decoder.target.mk:165: Release/obj.target/lwip_decoder/src/lib/png/png.o] Error 1

People suggest to replace lwip with jimp which (supposedly) has almost identical API.

Hi @IlyaSemenov

I haven't worked on this project since I uploaded it a few years ago and didn't know any one used it.

About your last test with lwip@latest, it looks like it's being discussed there. Looking at it quickly, it might require some image processing libraries installed on your instance, or to use node v6 instead of newer.

If you found it works better with jimp, I'll be happy to accept your pull request for that.

Same issue here with Ubuntu... shame the project hasn't been kept it up to date..

@IlyaSemenov, did you find a similar solution for thumnails in nodejs? Thx

[IlyaSemenov]

I came up with my own module (using sharp for image processing), and a caching layer in nginx.

[chrisben]

I dumped lwip in favour of sharp. Thanks for the tip.

[ausitpro]

regarding sharp - is there a way to pipe multer output to sharp prior to writing to disk? I asked this question on stackoverflow and was pointed to multer-resizer which depends on lwip. I've spent 2 days trying to resolve the similar lwip install issues and I'm ready to move on.
