[Rcpp-devel] unable to load shared object - Symbol not found

[Ismail SEZEN]

Hello all,

I had a package that I wrote myself with Rcpp code. After Rcpp 0.12.12 update, I can not build and install the package and I’m getting the error below:

** testing if installed package can be loaded
Error: package or namespace load failed for ‘rpbl’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/Users/isezen/Library/R/3.4/library/rpbl/libs/rpbl.so':
  dlopen(/Users/isezen/Library/R/3.4/library/rpbl/libs/rpbl.so, 6): Symbol not found: _rpbl_hef2
  Referenced from: /Users/isezen/Library/R/3.4/library/rpbl/libs/rpbl.so
  Expected in: flat namespace

Error: loading failed

The only difference is C++ native routines with underscore (in RcppExports.R and RcppExports.cpp files)  as mentioned in Dirk’s post.

Generate C++ native routines with underscore ("_") prefix to
             avoid exporting when standard exportPattern is used in
             NAMESPACE (JJ in #725 addressing #723).

the whole package and the code can be found here: https://github.com/isezen/rpbl
