Dear all,
I run
R CMD build --compact-vignettes="both" gRbase
and/or
R CMD build --compact-vignettes="gs+qpdf" gRbase
and in the log from r-devel (on winbuilder) I get
* checking sizes of PDF files under 'inst/doc' ... WARNING
'gs+qpdf' made some significant size reductions:
compacted 'gRbase-arrays.pdf' from 421Kb to 115Kb
consider running tools::compactPDF(gs_quality = "ebook") on these files
According to "writing R extensions" things should be fine (I have gs and qpdf
on my system):
"The --compact-vignettes option will run tools::compactPDF over the PDF files
in inst/doc (and its subdirectories) to losslessly compress them. This is not
enabled by default (it can be selected by environment variable
_R_BUILD_COMPACT_VIGNETTES_) and needs qpdf (http://qpdf.sourceforge.net/) to
be available. "
Can anyone please tell me what to do?
Best regards
Søren
