Question

我有一个私人R包，当我尝试安装时我得到错误，其中functInterp是我的包的名称

c:/Rtools/mingw_32/bin/g++ -shared -s -static-libgcc -o functInterp.dll tmp.def RcppExports.o empTraceVariogram.o empTraceVariogramTemp.o -Ld:/Compiler/gcc-4.9.3/local330/lib/i386 -Ld:/Compiler/gcc-4.9.3/local330/lib -LC:/PROGRA~1/R/R-34~1.2/bin/i386 -lR empTraceVariogramTemp.o:empTraceVariogramTemp.cpp:(.text+0x180):undefined reference to  dnrm2_'
  empTraceVariogram.o:empTraceVariogram.cpp:(.text+0x5bb): undefined
  reference todnrm2_' empTraceVariogram.o:empTraceVariogram.cpp:(.text+0x5f8): undefined reference to `ddot_'

在得到答案之后

：

这是RcppArmadillo或函数的错误吗？

Answer 1

您的链接说明有误。从使用RcppArmadillo的软件包中查看任何src/Makevars.win并使用它：

## optional
#CXX_STD = CXX11

PKG_CXXFLAGS = $(SHLIB_OPENMP_CXXFLAGS) 
PKG_LIBS = $(SHLIB_OPENMP_CFLAGS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)

其中$(SHLIB_OPENMP_CXXFLAGS)对您来说是可选的，但Armadillo现在想要它。

安装R包时未定义的参考
