Package poppler was not found in the pkg-config search path

[msageryd]

I'm not able to build poppler-simple. I've tried a lot of combos.

• Node 6, 8, 10
• OSX
• Debian (via docker)
• Alpine (via Docker)

Poppler installs fine in all the above scenarios (using brew, apt-get and apk respectively), but npm install gives the following error.

Does anyone have any clue? I did get poppler-simple to work on another computer (not available anymore). I'd really like to get this running in a Docker container.

Perhaps you should add the directory containing `poppler.pc'
to the PKG_CONFIG_PATH environment variable

Hi.
Please try to run pkg-config --libs poppler in your environment and inspect the output.

I found some random ubuntu for an example and got the following output:

~$ pkg-config --libs poppler
The program 'pkg-config' can be found in the following packages:
 * pkg-config
 * pkgconf
Try: sudo apt install <selected package>

i.e. pkg-config is not installed, but pkg-config it required for build script to work.

Thanks.
I think pkg-config is installed correctly, as the error message comes from pkg-config.

Could it be the other way around, i.e. the package directory in pkg-config does not contain poppler or points to the wrong path.

Does anyone know where poppler.pc resides? Actually I can't find it at all..

I should probably try to add this path to PKG_CONFIG_PATH if I find it.

Here is the Dockerfile. I've stripped it down to the essentials about poppler. I now realise that this has nothing with poppler-simple to do. But I'm hoping someone here has any clue anyway.

N.B. I also tried with FROM alpine to ensure that node doesn't interfere. Same result..

FROM node:10-alpine
RUN apk --update --upgrade add pkgconfig python poppler
RUN pkg-config --libs poppler

The result is:

Step 4/4 : RUN pkg-config --libs poppler

Looks like poppler pc files is in poppler-dev package.

Thanks, this got me a bit further. I installed poppled-dev instead of popplerand got rid of the pkg-config error. Unfortunately I got a bunch of new errors. I tried with Node 4, 6, 8 and 10.

The console gets flooded with messages, but here is the last part:

The console flood starts like this:

Here is the much simplified Dockerfile I'm trying to get working:

FROM node:10-alpine

RUN apk --update add alpine-sdk pkgconfig poppler-dev bash
COPY package.json /tmp/package.json
RUN cd /tmp && npm install

And the package.json

{
  "name": "poppler-test",
  "version": "1.0.0",
  "private": true,
  "dependencies": {
    "poppler-simple": "^0.3.0"
  }
}

There is a lot of flood during build but looks like everything works with node:8-alpine.
Please swith to it if possible. I will schedule update for node v10.

[msageryd]

Thanks again.
That's great news. I tried all Node versions and assumed the same error due to the flood of bright red messages. But now I see that the actual outcome is "success" on Node 8.

Thank you very much for your help. Would you like me to send you a PR with a small write-up on installing on Docker? I think it could help many others to get going wit poppler-simple.
