我目前正在与RcppArmadillo一起编写R包packageFoo
。但是,我在linux中编译我的包有问题。如果有人可以帮助我,我会很高兴。我不知道我做错了什么。
我只有一个带有以下标题的cpp文件:
#include <stdio.h>
#include <string>
#include <bitset>
#include <fstream>
#include <algorithm>
#include <iostream>
#include <cmath>
#include <RcppArmadillo.h>
// [[Rcpp::depends(RcppArmadillo)]]
using namespace Rcpp;
当我devtools::load_all()
时,我得到以下内容:
* installing *source* package ‘packageFoo’ ...
** libs

我用Google搜索,发现dgesdd_
是lapack
的一部分。检查与ldd
packageFoo.so
的{{1}}链接并不会显示任何链接的lapack
库。

我的MakeVars
文件如下所示:
PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
如RcppArmadillo文档中所述。运行R CMD config LAPACK_LIBS
会返回-llapack
我正在使用Rcpp_0.12.4
,RcppArmadillo_0.6.700.3.0
和devtools_1.11.0
答案 0 :(得分:3)
您的包裹或设置与您引用的链接行有问题:
g++ -shared -L/usr/lib/R/lib -Wl,-Bsymbolic-functions -Wl,-z,relro \
-o packageFoo.so RcppExports.o functions.o \
-L/usr/lib/R/lib -lR
不包含LAPACK / BLAS库。
也许可以通过RcppArmadillo.package.skeleton()
从简单包开始并比较?

问题在于Makevars
文件的名称。具体来说,将MakeVars
的名称更改为Makevars
(Unix / Linux)或Makevars.win
(Windows),并确保将其放在src/
目录中。
