Building PDFium inside a Ubuntu:latest Docker container

[Alexander Reen]

Heyya,

I'm trying to build PDFium inside a Ubuntu:latest docker container through a Docker File. As of now I got the following going:

# Install PDFium

RUN git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

ENV PATH /depot_tools:"$PATH"

RUN gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git; \

    gclient sync; \

    cd pdfium; \

    gn gen codeBuild

This results into the following error:

________ running '/usr/bin/python pdfium/build/vs_toolchain.py update' in '/'

________ running '/usr/bin/python pdfium/third_party/instrumented_libraries/scripts/download_binaries.py' in '/'

I follow this up by adding build/linux/sysroot_scripts/install-sysroot.py --arch=amd64 to the Dockerfile run command:

# Install PDFium

RUN git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

ENV PATH /depot_tools:"$PATH"

RUN gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git; \

    gclient sync; \

    cd pdfium; \

    build/linux/sysroot_scripts/install-sysroot.py --arch=amd64; \

    gn gen codeBuild

It follows up with the following output and error:

Not sure what's going wrong. Any thoughts?

Found out the issue. Was missing glib included in libgtk2.0-dev. For anyone trying to get PDFium into a Docker container based on Ubuntu, here is the code:

FROM ubuntu:latest

RUN apt-get update

RUN apt-get -qq update

RUN apt-get install -y git g++ curl libfreetype6 libgtk2.0-dev

RUN git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

ENV PATH /depot_tools:"$PATH"

RUN gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git; \

    gclient sync

RUN cd pdfium; \

    build/linux/sysroot_scripts/install-sysroot.py --arch=amd64; \

    gn gen codeBuild; \

    ninja -C codeBuild

You don't have to run build/linux/sysroot_scripts/install-sysroot.py.
You can just set use_sysroot = false, as recommended in README.md.

Ahh forgot the container is ofcourse Linux and thus build configs have to be different.

Can I pass such parameters through gn args in the way the docs state for listing as an example? I prefer not to manually use the editor due the automation of docker build.

gn args --args='use_sysroot="false" pdf_is_standalone ="true"'

Yes, you can do this from the command line without an editor. PDFium
has build bots that require automation as well.

gn gen out/foo --args='use_sysroot=false pdf_is_standalone=true'

Thanks for the help!

Parameters seem to work, yet pdf_is_standalone=true doesn't seem to work.

gn gen codeBuild --args='use_sysroot=false pdf_is_standalone=true'; \

    ninja -C codeBuild

This works but it still builds everything included unit tests.

The suggested way to get Pdfium_test by doing:

gn gen codeBuild --args='use_sysroot=false pdf_is_standalone=true'; \

    ninja -C codeBuild/pdfium_test

results in ninja stating pdfium_test dir doesn't exist. Even by a mkdir command to create that folder results in the same error.

The command you want is:

  ninja -C codeBuild pdfium_test

And preferably out/codebuild rather than codeBuild, if you want to run
unit tests for example. Our test runner code just assumes the base
directory is 2 levels up and does not try that hard to guess where it
is.
