R：在Linux上安裝Rcplex

Question

我在Linux上安裝Rcplex時遇到一些麻煩。

我試過了：

R CMD INSTALL --configure-args="                                      
--with-cplex-dir='/opt/ibm/ILOG/CPLEX_Studio129/cplex'"    Rcplex_0.3-3.tar.gz

然后我得到這個錯誤：

我也試過這個：

R CMD INSTALL     --configure-args="--with-cplex-include=/opt/ibm/ILOG/CPLEX_Studio129/cplex/include \
    --with-cplex-cflags=-fPIC \
    --with-cplex-lib=/opt/ibm/ILOG/CPLEX_Studio129/cplex/lib/x86-64_linux/static_pic' \
    -lcplex -lm -lpthread'" Rcplex_0.3-3.tar.gz 

並得到這個錯誤：

Answer 1

我認為您最好的做法是調查configure腳本嘗試運行的內容。 也許它期望CPLEX的另一個版本？

Answer 2

我在使用CPLEX 12.9的Ubuntu 18.04上為R3.6.1安裝Rcplex 0.3-3軟件包時遇到了同樣的問題。

事實證明，Rcplex軟件包是使用CPLEX 12.6.3開發和測試的。 當我在Ubuntu上安裝此舊版本的CPLEX時，可以按照INSTALL文件中的說明安裝Rcplex 0.3-3。

在我的系統上，此命令可以達到目的：

sudo R CMD INSTALL --configure-args="PKG_CFLAGS=-fPIC PKG_CPPFLAGS=-I/opt/ibm/ILOG/CPLEX_Studio1263/cplex/include PKG_LIBS='-L/opt/ibm/ILOG/CPLEX_Studio1263/cplex/lib/x86-64_linux/static_pic -lcplex -lm -lpthread'" Rcplex_0.3-3.tar.gz

這似乎僅與Rcplex的Linux版本有關。 我可以在Mac上使用最新版本的CPLEX安裝Rcplex。
