Question

我正在通过终端运行此示例。但是该行fatal error: RInside.h: No such file or directory发生#include<RInside.h>错误。它是从c ++到R的接口。我在R中有 RInside 软件包。我的代码：

#include<iostream>
#include<RInside.h>
using namespace std;
int main(){
    int a=12;
    cout<<a<<endl;
    return 0;  
}

#include<Rcpp.h>标头出现相同的错误。

#include <Rcpp.h>

using namespace Rcpp;

// [[Rcpp::export]]
NumericVector callFunction(NumericVector x, Function f) {
    NumericVector res = f(x);
    return res;
}

打包RInside版本0.2.14

软件包Rcpp版本0.12.17

GNUmakefile文件夹中的RInside附带的examples包括以下内容：

## comment this out if you need a different version of R, 
## and set set R_HOME accordingly as an environment variable
R_HOME :=       $(shell R RHOME)

[...]
## include headers and libraries for R 
RCPPFLAGS :=        $(shell $(R_HOME)/bin/R CMD config --cppflags)
RLDFLAGS :=         $(shell $(R_HOME)/bin/R CMD config --ldflags)
RBLAS :=        $(shell $(R_HOME)/bin/R CMD config BLAS_LIBS)
RLAPACK :=      $(shell $(R_HOME)/bin/R CMD config LAPACK_LIBS)

## if you need to set an rpath to R itself, also uncomment
#RRPATH :=      -Wl,-rpath,$(R_HOME)/lib

## include headers and libraries for Rcpp interface classes
## note that RCPPLIBS will be empty with Rcpp (>= 0.11.0) and can be omitted
RCPPINCL :=         $(shell echo 'Rcpp:::CxxFlags()' | $(R_HOME)/bin/R --vanilla --slave)
RCPPLIBS :=         $(shell echo 'Rcpp:::LdFlags()'  | $(R_HOME)/bin/R --vanilla --slave)


## include headers and libraries for RInside embedding classes
RINSIDEINCL :=      $(shell echo 'RInside:::CxxFlags()' | $(R_HOME)/bin/R --vanilla --slave)
RINSIDELIBS :=      $(shell echo 'RInside:::LdFlags()'  | $(R_HOME)/bin/R --vanilla --slave)

## compiler etc settings used in default make rules
CXX :=          $(shell $(R_HOME)/bin/R CMD config CXX)
CPPFLAGS :=         -Wall $(shell $(R_HOME)/bin/R CMD config CPPFLAGS)
CXXFLAGS :=         $(RCPPFLAGS) $(RCPPINCL) $(RINSIDEINCL) $(shell $(R_HOME)/bin/R CMD config CXXFLAGS)
LDLIBS :=       $(RLDFLAGS) $(RRPATH) $(RBLAS) $(RLAPACK) $(RCPPLIBS) $(RINSIDELIBS)

如果使用GNU make，则可以按字面意义使用它。否则，您将不得不对其进行调整以适合您的构建环境。请查看提供的示例以获取更多详细信息。

Answer 2

使用g ++编译RInside时，应指定头文件的路径。在Mac OS X（10.14.2 Mojave）上有一个g ++参数列表供您参考，希望对您有所帮助。
