[Rcpp-devel] Unusual RInside compilation experiences

hi dirk,

i've been compiling RInside on windows with the new RTools based on GCC 4.9.
with stock settings, this all compiles successfully.

however, if i add "-std=c++11" to CXX_FLAGS, then the compilation fails. it
chokes on line 27 of RInside.cpp [1]. what makes this more interesting is
that this line is surrounded with an #ifndef WIN32, so this line shouldn't
even be in there (
https://github.com/eddelbuettel/rinside/blob/master/src/RInside.cpp#L25 )

if i comment lines 26, 27 out, then the compilation works.

this isn't actually a new problem for me, i've been commenting out lines 26,
27 for a couple of years now (my last toolchain was based on GCC 4.8.2), but
this is the first time i've had a simple reproducible example.

have you encountered this before?

with thanks

jonathon

notes about [1]: sorry it's hard to read, i couldn't copy/paste from the dos
terminal, so i screenshotted it, and attached it. but the mailing list
rejected it for being too large, so i OCRed it:
