最近使用R進行生物信息多組學分析，需要用到cplex，安裝走了不少彎路，記錄這個過程。
首先需要安裝cplex；我的安裝如下，
1.下載地址：cplex_studio1263.win-x86-64百度網盤：https://pan.baidu.com/s/1_d3rQIw8Uzv__btewMFlOA
2.cplex安裝好之后，需要配置環境變量。
3.從官網下載cplexAPI_1.3.3.tar.gz包，如果按照其默認安裝，出錯，找不到文件夾，原因是，獲取不到剛才安裝的cplex_studio1263的路徑，這就需要對其進行設置絕對路徑。
我的設置如下：參考github的安裝方式：https://github.com/bayesteecal/cplexAPI/blob/master/inst/INSTALL
里面src中的Makevars.win文件，指定真正的文件路徑
PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"C:\soft_install\cplex\cplex\include"
PKG_LIBS=-L"C:\soft_install\cplex\cplex\lib" -lm -lcplex1236
其中lcplex1236是你安裝cplex_studio1263對應的版本號。
但build之后出現如下錯誤。
C:\Users\openstack> R CMD INSTALL --build --no-multiarch .\cplexAPI_1.3.3.tar.gz

解決方法需要在Makevars.win第一句后面加入這句話：-DBUILD_CPXSTATIC
最終Makevars.win配置文件如下：
PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"C:\soft_install\cplex\cplex\include" -DBUILD_CPXSTATIC
PKG_LIBS=-L"C:\soft_install\cplex\cplex\bin\x64_win64" -lm -lcplex1263
在build ；install，
R CMD build --no-build-vignettes --no-manual --md5 C:\Users\{your name here}\Desktop\cplexAPI
R CMD INSTALL --build --no-multiarch .\cplexAPI_1.3.3.tar.gz
最后成功提示如下
** building package indices
** installing vignettes
** testing if installed package can be loaded from temporary location
** testing if installed package can be loaded from final location
** testing if installed package keeps a record of temporary installation path
* MD5 sums
packaged installation of 'cplexAPI' as cplexAPI_1.3.3.zip
* DONE (cplexAPI)
