[Rcpp-devel] fatal error: 'omp.h' file not found

Dear Rcpp development list members, I am trying to use OpenMP with Rcpp. The code (placed in omp_experiment.cpp file) is pretty basic: #include #include //[[Rcpp::plugins(openmp)]] //[[Rcpp::depends(RcppArmadillo)]] using namespace Rcpp; // [[Rcpp::export]] int timesTwo(int x) { return x

Re: [Rcpp-devel] fatal error: 'omp.h' file not found

Greetings and Salutations, OS X does not currently support OpenMP under the default compiler (clang). Hence, you are receiving an error as it relates to the header file not being found. For more details, see: https://cran.r-project.org/doc/manuals/r-release/R-exts.html#OpenMP-support

Re: [Rcpp-devel] fatal error: 'omp.h' file not found

One may also use clang-omp from Homebrew if you wish to still use clang on OS X, but have OpenMP. --Kevin On Mon, Mar 14, 2016 at 9:31 AM Balamuta, James Joseph < balam...@illinois.edu> wrote: > Greetings and Salutations, > > > > OS X does not currently support OpenMP under the default compiler

Sorry, I guess James' e-mail contains some directions, albeit not for RStudio specifically. I'll try them. Thanks. Anguel -Original Message- From: aakremena To: krthornt ; rcpp-devel Sent: Mon, Mar 14, 2016 11:45 am Subject: Re: [Rcpp-devel] fatal error: 'omp.h' file not fou

Re: [Rcpp-devel] fatal error: 'omp.h' file not found

You should (read: I've not tested this myself...) be able to assign clang-omp and clang-omp++ to CC and CXX, respectively, in your ~/.R/Makevars file. On Mon, Mar 14, 2016 at 9:31 AM Balamuta, James Joseph < balam...@illinois.edu> wrote: > Greetings and Salutations, > > > > OS X does not currently

Hi everyone and thank you for your advice. Seems like a possible solution for the problem on OS X Mavericks is as follows: 1. Install clang-omp, If you use homebrew as a package management system, insert in terminal brew install clang-omp 2. Change the content o

I did a little more investigating about the 'mixed g++' compilers. It appears as if R-2.15 was built with a different version of GCC than is available on my system. strings -a /pkgs/r_2.15.3/bin/Rscript | grep GCC GCC: (GNU) 4.4.6 20120305 (Red Hat 4.4.6-4) GCC: (GNU) 4.4.7 20120313 (Red Hat 4.4
