[Rcpp-devel] Symbol not found when including an external library

[Simon Zehnder]

Follow-up: I found a connection to this error when running through the libraries: the function for which the symbol is not found is defined in line 85  of the stl_list.h. It is included into the libstdc++.a/libstdc++.dylib which is linked to the nloptr/nlopt build. As the build inside R throws an error, but not so the standalone build I assume, that R uses another libstdc++ library....

When I install nloptr on the linux server of our cluster all runs fine. The point, that I can build the nlopt library with my gcc compiler makes me hope to find the error in the R installation (R-patched 3.0.1, although I built the gcc with --disable-static).
