Hi Kevin, Yes, those extra includes are there because some functions taken from the MASS package need these them.
I rearranged the includes by placing #include <RcppArmadillo.h> before the ones below, and was able to reduce the number of errors from 7 to 4. #include <R_ext/Linpack.h> #include <R_ext/Applic.h> #include <R_ext/Utils.h> Is it possible for you to take a look at the script below, which includes those functions from MASS that require these includes? I am not sure what else needs to be done. The errors seem to have to do with the fortran library. https://www.dropbox.com/s/ukjml693ta8r8gi/test2.cpp?dl=0 Thank you!! -Xiao On Wed, Sep 3, 2014 at 6:49 PM, Kevin Ushey <kevinus...@gmail.com> wrote: > Hi Xiao, > > I can reproduce the error -- but why do you have the includes as such, > e.g.: > > #include <R.h> > #include <float.h> > #include <R_ext/Linpack.h> > #include <R_ext/Applic.h> /* for the QR routines */ > #include <R_ext/Utils.h> /* for the *sort() routines */ > #include <stdio.h> > #include <RcppArmadillo.h> > #define BIG DBL_MAX > > > My best guess is that you'll have to re-organize the includes, or put in > some corresponding `#define` and `#undef`s to clean up some macro pollution > that seems to be leaking out.
