Dear all,I have an R package that I plan to submit to CRAN in the near future,
but it gave me a note when I ran "R CMD check --as-cran" saying that my
libs directory is 7.0Mb. I wrote some functions in C++ and my source
code included several low-level C++ libraries as header files. When I
compiled manually using g++ without the -g flag, my shared library (.so)
was about 400Kb; but when I compiled with the -g flag, it was about
7.0Mb... I am assuming there was a lot of debugging information created
when I turned on -g, possibly because the compiler had to look for a lot
of classes and functions in low-level C++ libraries, but I am worried
that the package would fail CRAN check due to the large size .so file
created (it seems R has -g flag on by default when compiling C/C++ code
according to ${R_HOME}/etc/Makeconf). Does anyone have any suggestions
on how I could possibly make my shared library file smaller? Even though
I can compile it manually without the -g flag, general users will !
use R default to install the package and it could take a lot of space.
Thanks in advance!7MB is not 'a lot of space'. There are CRAN packages which compiled with -g take ca 80MB.
