Boom package takes over 600 mb after installing with R #58

I am trying to install BSTS R package on a docker container. Boom package is installed in usr/local/lib/R/site-library/Boom. However, the size of the file libboom.a is over 600 mb.

Is there a way to reduce the file size for this file as I am trying to make my container leaner.

To reproduce this, build using this Dockerfile:

FROM rocker/r-base:4.1.0 AS compile-image
RUN apt-get update \
    && mkdir $HOME/.R
COPY Makevars .R/

RUN wget "https://cran.r-project.org/src/contrib/Boom_0.9.7.tar.gz"
RUN R CMD INSTALL --strip --clean "Boom_0.9.7.tar.gz"

I added the --strip argument as it is suggested in this blog post.

This is the Makevars file:

SHLIB_CXXLDFLAGS = -Wl,-S -shared
SHLIB_CXX11LDFLAGS = -Wl,-S -shared
SHLIB_CXX14LDFLAGS = -Wl,-S -shared
SHLIB_FCLDFLAGS = -Wl,-S -shared
SHLIB_LDFLAGS = -Wl,-S -shared

# strip debug symbols for smaller Linux binaries
strippedLib: $(SHLIB)
    if test -e "/usr/bin/strip" & test -e "/bin/uname" & [[ `uname` == "Linux" ]] ; \
        then /usr/bin/strip --strip-debug $(SHLIB); fi
.phony: strippedLib

If you manually strip the library using the bash "strip" utility it will be significantly smaller.

Thank you Steve for your reply.

I ran strip --strip-unneeded usr/local/lib/R/site-library/Boom/lib/libboom.a after installing the library. The file size reduced to just 30mb. Hope it does not affect the BSTS package.
