I get the error undefined symbol: Rf_rownamesgets when I try to load my package, which include C++ code that calls that function. This is particularly strange since the code also calls Rf_classgets, and it loaded OK with just that.
Can anyone tell me what's going on? For the record, I worked around this with the general purpose attribute setting commands and R_RowNamesSymbol. I discovered that even with that I wasn't constructing a valid data.frame, and fell back to returning a list of results. I notice Rinternals.h defines LibExtern SEXP R_RowNamesSymbol; /* "row.names" */ twice in the same block of code. I'm using R 2.4.1 on Debian. The symbol seems to be there: $ nm -D /usr/lib/R/lib/libR.so | grep classgets 00032e70 T Rf_classgets $ nm -D /usr/lib/R/lib/libR.so | grep namesgets 00031370 T Rf_dimnamesgets 00034500 T Rf_namesgets The source includes #define R_NO_REMAP 1 #include <R.h> #include <Rinternals.h> and later #include <memory> // I think this is why I needed R_NO_REMAP I realize this is not a complete example, but I'm hoping this will ring a bell with someone. I encountered this while running R CMD check.
