<body class='hmmessage'><div dir='ltr'><span>Hi all,<br><br>I have a problem using simultaneously RCPP and Snow with Rstudio. The problem only appears when I use Rstudio, and the code runs well when using RGUI.<br>I wrote a cpp function that I want to run in parallel. So I use Snow and compile the function on each node as follow:<br><br>library(parallel)<br>library(Rcpp)</span><br><span><span>library(RcppArmadillo)<br></span>cl = makeCluster(nnodes, type = "SOCK")<br>clusterEvalQ(cl, library(Rcpp))<br> clusterEvalQ(cl, library(RcppArmadillo))<br> clusterEvalQ(cl, setwd(my_path))<br> clusterEvalQ(cl[i], sourceCpp("Rcpp/function.cpp"))<br><br>The produced error is the following:<br><br></span><span><span>Error in checkForRemoteErrors(lapply(cl, recvResult)) : <br> one node produced an error: Error 1 occurred building shared library.<br><br></span>Have you ever had this problem? Is it necessary to configure Rstudio in a particular way in order to make it work?<br>Thanks,<br><br>Maxime<br></span> </div></body>
