[英]Compiling C code that uses R libraries in Netbeans
I've been having trouble debugging some C code that I'm writing as part of an R package. 我一直在调试作为R包的一部分编写的某些C代码时遇到麻烦。 The code compiles and executes when I use
R CMD SHLIB
from the Windows console (ie cmd.exe): 当我从Windows控制台(即cmd.exe)使用
R CMD SHLIB
时,代码将编译并执行:
>R CMD SHLIB MaximumAgreementForest.c
gcc -m64 -I"C:/PROGRA~1/R/R-32~1.4RE/include" -DNDEBUG -I"d:/RCompile/r-compiling/local/local323/include" -O2 -Wall -std=gnu99 -mtune=core2 -c MaximumAgreementForest.c -o MaximumAgreementForest.o
gcc -m64 -shared -s -static-libgcc -o MaximumAgreementForest.dll tmp.def MaximumAgreementForest.o -Ld:/RCompile/r-compiling/local/local323/lib/x64 -Ld:/RCompile/r-compiling/local/local323/lib -LC:/PROGRA~1/R/R-32~1.4RE/bin/x64 -lR
The script also built correctly in Netbeans until I started using the functions R_alloc
and C_alloc
from the R libraries. 在我开始使用R库中的函数
R_alloc
和C_alloc
之前,该脚本还在Netbeans中正确构建。 Now it doesn't seem to be able to find the definitions of a number of R-specific functions. 现在看来似乎无法找到许多R特定功能的定义。 When I attempt to build the project in Netbeans the console lists the following:
当我尝试在Netbeans中构建项目时,控制台将列出以下内容:

My script, a single .c file, contains the lines 我的脚本是一个.c文件,包含以下几行
#define USE_RINTERNALS
#include <R.h> // which itself #includes R_ext/Memory, R_ext Printf
#include <R_ext/Print.h>
#include <R_ext/Memory.h>
#include <Rinternals.h>
Figuring that Netbeans is failing to point to the relevant libraries, I have tried adding and removing C:/Program Files/R/R-3.2.4revised/include
and C:/Program Files/R/R-3.2.4revised/bin/x64
at File→Project Properties→General→Source folders , to no effect. 考虑到Netbeans无法指向相关库,我尝试添加和删除
C:/Program Files/R/R-3.2.4revised/include
和C:/Program Files/R/R-3.2.4revised/bin/x64
在文件→项目属性→常规→源文件夹下为C:/Program Files/R/R-3.2.4revised/bin/x64
,无效。
Under File→Project Properties→Build→C compiler , I have included C:/Program Files/R/R-3.2.4revised/include
. 在文件→项目属性→构建→C编译器下 ,我包含了
C:/Program Files/R/R-3.2.4revised/include
。
When I add C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll
to Build→Linker→Libraries→Libraries , via the Add Library... option, I receive the error c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: cannot find -lR
, and the linker exits without (before?) complaining about the undefined references. 当我通过Add Library ...选项将
C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll
到Build→Linker→Libraries→Libraries时 ,收到错误c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: cannot find -lR
,并且链接器在没有(before?)的情况下退出抱怨未定义的引用。
When I subsequently add "C:/Program Files/R/R-3.2.4revised/bin/x64/", which is already in by System PATH, to Build→Linker→Additional Library Directories , the compiler fails with the message C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll: file not recognized: File format not recognized
随后,当我将系统路径已包含的“ C:/ Program Files / R / R-3.2.4revised / bin / x64 /”添加到Build→Linker→Additional Library Directories时 ,编译器将失败,并显示消息
C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll: file not recognized: File format not recognized
What am I missing... how can I point Netbeans to the relevant R libraries? 我缺少什么...如何将Netbeans指向相关的R库?
The File format not recognized
error is encountered when a 32-bit compiler tries to load to a 64-bit .dll (or vice-versa). 当32位编译器尝试加载到64位.dll时遇到
File format not recognized
错误(反之亦然)。 Changing the path C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll
to C:/Program Files/R/R-3.2.4revised/bin/i386/R.dll
resolved the problem. 将路径
C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll
为C:/Program Files/R/R-3.2.4revised/bin/i386/R.dll
解决了此问题。
