Question

我在调试一些我作为R包的一部分编写的C代码时遇到了问题。当我从Windows控制台使用R CMD SHLIB（即cmd.exe）时，代码会编译并执行：

>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

该脚本也在Netbeans中正确构建，直到我开始使用R库中的函数R_alloc和C_alloc。现在它似乎无法找到许多R特定函数的定义。当我尝试在Netbeans中构建项目时，控制台会列出以下内容：

cd 'C:\Work\Fun\implied_weight\MAF'
C:\MinGW\msys\1.0\bin\make.exe -f Makefile CONF=Debug
"/C/MinGW/msys/1.0/bin/make.exe" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

[...]
C:\Work\Fun\implied_weight\MAF/../MaximumAgreementForest.c:515: undefined reference to `R_chk_free'
collect2.exe: error: ld returned 1 exit status

我的脚本，单个.c文件，包含行

#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>

认为Netbeans未能指向相关库，我尝试在文件→项目属性→常规→源文件夹中添加和删除C:/Program Files/R/R-3.2.4revised/include和C:/Program Files/R/R-3.2.4revised/bin/x64，没有效果。

在文件→项目属性→构建→C编译器下，我已添加C:/Program Files/R/R-3.2.4revised/include。

当我将<{1}}添加到构建→链接器→库→库时，通过添加库... 选项，我收到错误{{1并且链接器退出时没有（在？之前）抱怨未定义的引用。

当我随后在系统路径中添加＆＃34; C：/ Program Files / R / R-3.2.4revised / bin / x64 /＆＃34;时， Build→Linker→其他库目录，编译器失败并显示消息C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll

我错过了什么......我如何将Netbeans指向相关的R库？

Answer 1

当32位编译器尝试加载到64位.dll（或反之亦然）时，会遇到File format not recognized错误。改变路径 C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll 至 C:/Program Files/R/R-3.2.4revised/bin/i386/R.dll 解决了这个问题。
