[R-pkg-devel] Solaris package installed size

[Dalgleish, James (NIH/NCI) [V]]

On Solaris, I'm finding that my package, only on Solaris, is slightly above 5MB. Is there a difference in install sizes for Solaris? I don't have a Solaris machine, so it's difficult to know what the size differences are and why.
https://www.r-project.org/nosvn/R.check/r-patched-solaris-x86/CNVScope-00check.html
"checking installed package size ... NOTE
  installed size is 5.2Mb
  sub-directories of 1Mb or more:
    doc 3.1Mb
    extdata 1.8Mb"

If so, why might that be?
I've looked at R solaris documentation (https://cran.r-project.org/doc/manuals/r-release/R-admin.html#Solaris), but it says nothing other than suggesting that it will require more stack space (memory) to build the package... but this doesn't say anything about disk space or installation directory cleanup differences.

"At least when compiling with Oracle compilers, Solaris uses far more stack space than other platforms."  Perhaps there are additional files that are generated for Solaris that are not generated for other platforms?

Thanks,
James Dalgleish
