Question

我已使用以下指南安装了CplexApi软件包：https://www.r-bloggers.com/using-cplex-in-r-installing-cplexapi-in-windows-10/

我现在正试图以类似的方式安装Rcplex软件包。我已将makevars.win文件编辑为以下内容：

ifeq "$(WIN)" "64"
PKG_LIBS = -L"C:/Program Files/IBM/ILOG/CPLEX_Studio128/cplex/x64_win64" -lcplex1280 -lm
PKG_CPPFLAGS = -D_LP64 -I"C:/Program Files/IBM/ILOG/CPLEX_Studio128/cplex/include"
else
PKG_LIBS = -L"C:/Program Files/IBM/ILOG/CPLEX_Studio128/cplex/bin/x86_win32" -lcplex1280 -lm
PKG_CPPFLAGS = -I"C:/Program Files/IBM/ILOG/CPLEX_Studio128/cplex/include"
endif

然后我在CMD中输入以下内容：

C:\Users\A>R CMD build --no-build-vignettes --no-manual --md5 C:\Users\A\Downloads\cPlex\Rcplex_0.3-3.tar\Rcplex_0.3-3\Rcplex

这就是输出：

* checking for file 'C:\Users\A\Downloads\cPlex\Rcplex_0.3-3.tar\Rcplex_0.3-3\Rcplex/DESCRIPTION' ... OK
* preparing 'Rcplex':
* checking DESCRIPTION meta-information ... OK
* cleaning src
* checking for LF line-endings in source and make files and shell scripts
* checking for empty or unneeded directories
* adding MD5 file
* building 'Rcplex_0.3-3.tar.gz'
Warning: file 'Rcplex/cleanup' did not have execute permissions: corrected
Warning: file 'Rcplex/configure' did not have execute permissions: corrected`

然后我输入了以下内容：

C:\Users\A>R CMD INSTALL --build --no-multiarch .\Rcplex_0.3-3.tar.gz

我把它作为输出：

In R CMD INSTALL
* installing to library 'C:/Users/A/Documents/R/win-library/3.5'
* installing *source* package 'Rcplex' ...
** package 'Rcplex' successfully unpacked and MD5 sums checked

我想知道我到底做错了什么？

尝试在R中安装Rcplex程序包时出现编译错误
