对于致命错误

Question

我运行这个例子，通过终端。但得到fatal error: RInside.h: No such file or directory错误的线路，#include<RInside.h>。它是一种从C ++至R接口。我有RInside包河我的代码：

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

对于#include<Rcpp.h>头发生同样的错误。

#include <Rcpp.h>

using namespace Rcpp;

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

包装RInside版本0.2.14

包装RCPP版本0.12.17

随在GNUmakefile文件夹RInside的examples包括像：

## 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)

如果你使用GNU做，你也许可以从字面上使用。否则，你将不得不适应它为构建环境。请看有关详细信息，所提供的例子。

与G ++编译RInside时，应指定头文件的路径。目前在Mac OS X（10.14.2莫哈韦）供您参考G ++的参数列表，希望这帮助。

g++ 
-I/Library/Frameworks/R.framework/Versions/3.5/Resources/library/RInside/include \
-I/Library/Frameworks/R.framework/Versions/3.5/Resources/library/Rcpp/include \
-I/Library/Frameworks/R.framework/Versions/3.5/Resources/include \
-L/Library/Frameworks/R.framework/Versions/3.5/Resources/lib \
-L/Library/Frameworks/R.framework/Versions/3.5/Resources/library/RInside/lib \
-lR -lRInside -O3 -o test helloworld_rinside.cpp
