[R-pkg-devel] gcc-asan replication for armadillo

[@@drew m@iii@g oii robbi@s@@me]

If this were the case I don't think that I'd be having problems replicating it.

Perhaps weirder, it seems to be triggered by an inclusion of armadillo_bits/constants.hpp in both my shared object and the Rcpp binding library-which seems like something that shouldn't be raising any issues.



Seemingly, yes. ODR stands for _One_ Definition Rule so if you define

the same thing in two different libs then raising issue sounds legitimate.

I suppose one possible solution could be incorporating the content of

libnmflib.so (and all other libs your build) directly in RcppPlanc.so

and cleaning them afterward.



Hoping it helps,

Serguei.
