我在调试一些我作为R包的一部分编写的C代码时遇到了麻烦。当我从Windows控制台(即cmd.exe)使用R CMD SHLIB时，代码编译和执行:
>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
脚本也在Netbeans中正确构建，直到我开始使用R库中的R_alloc和C_alloc函数。现在它似乎不能找到一些特定于r的函数的定义。当我尝试在Netbeans中构建项目时，控制台列出以下内容:
cd 'C:WorkFunimplied_weightMAF'

认为Netbeans无法指向相关库，我尝试在文件→项目属性→常规→源文件夹添加和删除C:/Program Files/R/R-3.2.4revised/include和C:/Program Files/R/R-3.2.4revised/bin/x64，但没有效果。
在File→Project Properties→Build→C compiler下，我包含了C:/Program Files/R/R-3.2.4revised/include .
当我添加C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll到Build→Linker→Libraries→Libraries时，通过 add Library…选项，我收到错误c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: cannot find -lR，链接器退出，没有(之前?)抱怨未定义的引用。
当我随后添加"C:/Program Files/R/R-3.2.4revised/bin/x64/"，它已经在系统路径中，到Build→Linker→Additional Library Directories，编译器失败，显示C:/Program Files/R/R-3.2.4revised/bin/x64/R.dll: file not recognized: File format not recognized
当32位编译器试图加载到64位.dll(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来C:/Program Files/R/R-3.2.4revised/bin/i386/R.dll问题解决
