Error in dyn.load(libLFile)

[barracuda156]

Could someone advise me on the following error:

RcppParallels is built and installed. From what I understand, it has its own version of TBB, however for whatever reason Rstan does not load it. (Building standalone TBB fails on PowerPC, at least as of now, so that is not an option.)

Basic Rcpp functionality works:

fx <- inline::cxxfunction( signature(x = "integer", y = "numeric" ) , '

• return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ;
• ' )

fx( 2L, 5 ) [1] 10
