Hello everybody,
this is my very first post on this mailing list so if I have made any mistakes please feel free to point me to it.
I have written a package for R. This package internally uses Rcpp-Modules. However my package got rejected from CRAN due to the fact that my package can not be loaded under Solaris. So, i set up a virtual machine with Solaris 10 to find the error in my code. For now it appears to me, that it is not possible to use Rcpp-Modules under Solaris using Oracle Studio 12 compilers (which are used by CRAN as far as i know).
I created a minimal example through:
"Rcpp.package.skeleton("somename", module=TRUE)"
I removed every file from the "src"-folder except the "Num.cpp" file and reduced the content of the "zzz.R" file located in the "R" folder to the single line "loadModule("NumEx", TRUE)".
Compiling this minimal example with the latest version of R using the Oracle Studio 12 compilers results in the output given below. Also i have used the following enviroment variables (which are used by CRAN too):
