[Rcpp-devel] loading failed

[Fabio Tordini]

Ok, I found the 'scrm' Rcpp package: here the file scrmr.cpp provides an 
interface for calling the scrm C++ application from R. following their 
solution, I modified my Makevars file, adding:

OBJECTS.PnuChart = ngraph.o RcppExports.o
OBJECTS.PnuChart = PnuChart/Finder.o
OBJECTS = $(OBJECTS.PnuChart)

Now the linker finds the object files and knows where functions "are". 
so, previous error is solved.

but loading still fails with the following message:

  /home/fabio/R/x86_64-pc-linux-gnu-library/3.0/NgrapH/libs/NgrapH.so: 
undefined symbol: gsl_vector_alloc
Error: loading failed

In fact, I do use gsl, that's why I added RcppGSL in the DESCRIPTION 
file at 'LinkingTo'. Also, I use the attribute
'// [[Rcpp::depends(RcppGSL)]]' in those headers where GSL functions are 
used, and included <RcppGSL.h>. I do not export those functions because 
they're not called directly from R.

still, I get the loading failed error.
