在Windows R中使用openmp，rtools是否支持openmp? [英] using openmp in windows R, does rtools support openmp?

问题描述

当尝试在C ++代码中使用openmp在Windows 7上构建我的R包时，我收到很多错误消息:

c:/rtools/mingw/bin/../lib/gcc/mingw32/4.5.0/libgomp.a(parallel.o):(.text+0x19): undefined      reference to `_imp__pthread_getspecific'
c:/rtools/mingw/bin/../lib/gcc/mingw32/4.5.0/libgomp.a(parallel.o):(.text+0x7a): undefined reference to `_imp__pthread_mutex_lock'
c:/rtools/mingw/bin/../lib/gcc/mingw32/4.5.0/libgomp.a(env.o):(.text+0x510): undefined reference to `_imp__pthread_mutex_init'

...

Rtools是否不支持openmp? 有谁知道如何在Windows R软件包中使用openmp?

解决方案

否，根据 Rcpp开发列表中. >

R本身在Windows上不使用OpenMP，因此Rtools不支持.在其他操作系统上，R当然也具有OpenMP支持.

I got lots of error messages when trying to use openmp in a c++ code for building my R package on windows 7:

c:/rtools/mingw/bin/../lib/gcc/mingw32/4.5.0/libgomp.a(parallel.o):(.text+0x19): undefined      reference to `_imp__pthread_getspecific'

Is Rtools not supporting openmp? Does anyone know how to use openmp in windows R packages please?

解决方案

No, per discussions on the R-devel mailing list. It also came up on the Rcpp-devel list.

R itself does not use OpenMP on Windows, so there is not support in Rtools. On other OSs R does of course have OpenMP support.
