https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221126 Bug ID: 221126 Summary: devel/R-cran-data.table: missing openMP support Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: tota@FreeBSD.org Reporter: rs.os@t-online.de Assignee: tota@FreeBSD.org Flags: maintainer-feedback?(tota@FreeBSD.org) Hello, thanks for providing the great data.table package as a precompiled package! Loading the package in R results in following message: ``` data.table 1.10.4 ********** This installation of data.table has not detected OpenMP support. It will st= ill work but in single-threaded mode. If this a Mac and you obtained the Mac bi= nary of data.table from CRAN, CRAN's Mac does not yet support OpenMP. In the meantime please follow our Mac installation instructions on the data.table homepage. If it works and you observe benefits from multiple threads as oth= ers have reported, please convince Simon Ubanek by sending him evidence and ask= him to turn on OpenMP support when CRAN builds package binaries for Mac. Alternatives are to install Ubuntu on your Mac (which I have done and works well) or use Windows where OpenMP is supported and works well. ********** The fastest way to learn (by data.table authors): https://www.datacamp.com/courses/data-analysis-the-data-table-way Documentation: ?data.table, example(data.table) and browseVignettes("data.table") Release notes, videos and slides: http://r-datatable.com ``` Per default is R compiled without OpenMP support as it would require gcc. M= aybe it is possible to provide only the data.table package with OpenMP support (= gcc is already a dependency)? Thanks for your efforts! --=20 You are receiving this mail because: You are the assignee for the bug.=
