Package Compilation fails when package name contain a "dot" and Rcpp function

I am building a new package:

  • The package name contains a dot: for example my.package
  • The package exports one Rcpp function: for example rcppfunction

When I build the package using Rcmd INSTALL, compileAttributes is used behind the scene to automatically generate exported function, 

RcppExport SEXP my.package_rcppfunction(...)

and I get a compilation error due to the dot in the exported name:

RcppExports.cpp:10:19: error: expected initializer before '.' token

As a workaround , I can change the package name to remove the dot from it , but I want better solution and to understand how the symbols are exported. So my question is:

  1. How can I parametrize the generated code to replace dot by a "_" for example (Maybe by giving some parameters to the export attribute) .
  2. Or How to change the g++ call to force it to compile such dotted symbols..

I don't know if this can help , but here my g++ call:

g++ -m32 -I"PATH_TO_R/R-30~1.2/include" -DNDEBUG    -
I"PATH_To_R/3.0/Rcpp/include" -
I"d:/RCompile/CRANpkg/extralibs64/local/include"     
-O2 -Wall  -mtune=core2 -c RcppExports.cpp -o RcppExports.o
rcpp g++ r
