我目前正在开发一个 R 包，它使用 C++ 代码并包含外部库（dlib、boost 和小组开发的优化库）。我们使用 Rcpp 来集成 R 和 C++，但问题是该包总是无法编译，而且我发现的类似问题都对我不起作用。
R CMD 检查生成的报告为：
* installing *source* package 'IRTppExperimental' ...
** libs

Makevars/Makevars.win 文件如下：
INCFOLDER = ../src/include
PKG_LIBS += $(LAPACK_LIBS) $(BLAS_LIBS) $(FPICFLAGS) $(SHLIB)
PKG_LIBS += -L$(INCFOLDER)
PKG_CXXFLAGS+=-I$(INCFOLDER)
CXXFLAGS+="-fno-stack-protector"
CXX_STD = CXX11
最后，NAMESPACE 文件内容为：
exportPattern("^[[:alpha:]]+")
importFrom(Rcpp,sourceCpp)
useDynLib(IRTppExperimental)
所有 C++ 源文件都位于 src 文件夹内，包括外部库。该包是使用 Rcpp.package.sculpture 函数创建的，并使用compileAtributes 函数创建 RcppExports 源文件。
