[Rcpp-devel] Build failures under windows 64 on R-forge?

[Douglas Bates]

Could someone help me to understand the errors in the Windows x86_64
build of the lme4Eigen package?  See
https://r-forge.r-project.org/R/?group_id=60&log=build_win64&pkg=lme4Eigen&flavor=patched
for the errors.  The important part is

As far as I can tell, nothing has been defined before

#include <RcppEigen.h>

which is at line 12 of predModule.h  What mystifies me is why there is
a problem with long long int here but not in, say, the build of
RcppEigen itself for the same architecture.
