ragg installation in docker container

[tatvabodhini]

We are trying to build a shiny app in a container environment that takes ragg package to render custom fonts.

The docker build fails with the following message.
Full build log here: build_log.txt

-----------------------------------------------------

I have included all the system requirements as listed in the package description. Here is the full docker reproducible example.

FROM rocker/r-base:4.4.1

# Install dependencies for 'ragg'
RUN apt-get update && apt-get install -y --no-install-recommends \
    libpng-dev \
    libtiff5-dev \
    libjpeg-dev \
    libfreetype6-dev \
    && rm -rf /var/lib/apt/lists/*

RUN R -e "install.packages('shiny', repos='http://cran.rstudio.com/', dependencies=TRUE)"
RUN R -e "install.packages('ragg', repos='http://cran.rstudio.com/', dependencies=TRUE)"


RUN echo "local(options(shiny.port = 3838, shiny.host = '0.0.0.0'))" > /usr/lib/R/etc/Rprofile.site
RUN groupadd --system app && useradd --system --gid app app
WORKDIR /home/app
COPY app .

RUN chown app:app -R /home/app
USER app
EXPOSE 3838

At first glance it seems that something in the setup of the container prevents the configure script from setting the right flags during compilation, but I'm unsure what

Looking at that build.txt the installation fails in the systemfonts dependency, not in ragg. So this is the wrong issue tracker.

Your build.txt shows you installed freetype using --no-install-recommends. As a result it missed a dependency. If I try to recreate your setup I see this:

pkg-config --cflags fontconfig freetype2
# Package bzip2 was not found in the pkg-config search path.
# Perhaps you should add the directory containing `bzip2.pc'
# to the PKG_CONFIG_PATH environment variable
# Package 'bzip2', required by 'freetype2', not found

It looks like we are missing a transitive dependency. Installing libbz2-dev resolves the problem. You will find also need libharfbuzz-dev. But you can avoid these problems by not using --no-install-recommends.

@jeroen Thank you a bunch. Worked both the ways you suggested. --no-install-recommends - I am using it to reduce size of build.
