R安装cplexAPI弯路

最近使用R进行生物信息多组学分析，需要用到cplex，安装走了不少弯路，记录这个过程。

首先需要安装cplex；我的安装如下，

1.下载地址：cplex_studio1263.win-x86-64百度网盘：https://pan.baidu.com/s/1_d3rQIw8Uzv__btewMFlOA

2.cplex安装好之后，需要配置环境变量。

3.从官网下载cplexAPI_1.3.3.tar.gz包，如果按照其默认安装，出错，找不到文件夹，原因是，获取不到刚才安装的cplex_studio1263的路径，这就需要对其进行设置绝对路径。

我的设置如下：参考github的安装方式：https://github.com/bayesteecal/cplexAPI/blob/master/inst/INSTALL

里面src中的Makevars.win文件，指定真正的文件路径

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是你安装cplex_studio1263对应的版本号。

但build之后出现如下错误。

C:\Users\openstack> R CMD INSTALL --build --no-multiarch .\cplexAPI_1.3.3.tar.gz

解决方法需要在Makevars.win第一句后面加入这句话：-DBUILD_CPXSTATIC

最终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)
