R：安装 cplexAPI 错误

Question

I am trying to use cplexAPI in R. I am getting persistent errors. I am using Microsoft R Open 3.3.1 and have installed IBM ILOG CPLEX Optimization Studio Version: 12.7.0.0 on Windows 10. Here is what I have done, and what has resulted. I am going to go into painstaking detail on the hope that you see my error somewhere!

1. Unpacked the tar file to a folder on my desktop.
2. Edit the file: C:\\Users\\zejas\\Desktop\\cplexAPI\\cplexAPI\\src\\Makevars.win to say:

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"$C:\\Program Files\\IBM\\ILOG\\CPLEX_Studio127\\cplex\\include" PKG_LIBS=-L"$C:\\Program Files\\IBM\\ILOG\\CPLEX_Studio127\\cplex\\lib" -lm -lcplex1270

3. Microsoft put their own spin on the Reviron.site file. They put Rcmd_environ in: C:\\Program Files\\Microsoft\\MRO-3.3.1\\etc\\Rcmd_environ Within that file I added the bottom three lines:

## from R.sh R_SHARE_DIR=${R_HOME}/share R_INCLUDE_DIR=${R_HOME}/include R_DOC_DIR=${R_HOME}/doc R_ARCH= ## from Rcmd R_OSTYPE=windows TEXINPUTS=.;${TEXINPUTS};${R_SHARE_DIR}/texmf/tex/latex; BIBINPUTS=.;${BIBINPUTS};${R_SHARE_DIR}/texmf/bibtex/bib; BSTINPUTS=.;${BSTINPUTS};${R_SHARE_DIR}/texmf/bibtex/bst; ## from etc/Renviron # R_PLATFORM='i386-pc-mingw32' R_PAPERSIZE_USER=${R_PAPERSIZE} R_PAPERSIZE=${R_PAPERSIZE-'a4'} # for Rd2dpf, reference manual R_RD4PDF=${R_RD4PDF-'times,inconsolata,hyper'} ## used for options("texi2dvi") # R_TEXI2DVICMD=${R_TEXI2DVICMD-${TEXI2DVI-'texi2dvi'}} ## used by INSTALL, check, build R_GZIPCMD=${R_GZIPCMD-'gzip'} ## Default zip/unzip commands R_UNZIPCMD=${R_UNZIPCMD-'unzip'} R_ZIPCMD=${R_ZIPCMD-'zip'} R_BZIPCMD=${R_BZIPCMD-'bzip2'} ## Default browser # R_BROWSER=${R_BROWSER-'open'} ## Default editor # EDITOR=${EDITOR-${VISUAL-vi}} ## Default pager # PAGER=${PAGER-''} ## Default PDF viewer # R_PDFVIEWER=${R_PDFVIEWER-'open'} # MAKE=${MAKE-make} SED=${SED-sed} # CPLEX_STUDIO_DIR=C:/Program Files/IBM/ILOG/CPLEX_Studio127 CPLEX_STUDIO_LIB=C:/Program Files/IBM/ILOG/CPLEX_Studio127/cplex/bin/x64_win64

4. In Environment Variables System Variables Path I had already added:

5. I rebuild the package:

6. I attempt install of the package:

There absolutely is a cplex.h file in that directory!

Those are new errors!

Answer 1

For me it looks as you have left the $ signs in front of the paths in the Makevars.win file. Please try to correct to:

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\include"
PKG_LIBS=-L"C:\Program Files\IBM\ILOG\CPLEX_Studio127\cplex\lib" -lm -lcplex1270

edit2: As baydoganm pointed out there are two functions missing in cplex 1270. When removing those, cplexAPI compiles fine with windows, too: cplexAPI_1.3.3.tar.gz

Answer 2

I was facing similar problem while integrating CPLEX with R, and installing the cplexAPI package, see https://cran.r-project.org/web/packages/cplexAPI/ there were few mistakes that I was doing, first of all, the problem arises because R does not know where IBM CPLEX is installed, so you have to manually change the file Makevars.win in the cplexAPI_1.3.3.tar.gz package that is downloaded while you were trying to install cplexAPI from rstudio GUI. look for following codes:

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"${CPLEX_STUDIO_DIR}\cplex\include"
PKG_LIBS=-L"${CPLEX_STUDIO_LIB}" -lm -lcplex1261

two thing that you need to check is -L"${CPLEX_STUDIO_LIB}" is replaced by in my case, -L"C:/Program Files/IBM/ILOG/CPLEX_Studio1271/cplex/bin/x64_win64" (see bin/x64_win64) , replace $ too

second inside the folder x64_win64, look for cplex12**.dll file, this the file where -lcplex1261 is pointing to, here manually change -lcplex1261 to whatever your file name is (in my case it was cplex1271.dll, so I changed -lcplex1261 to -lcplex1271,

similarly ${CPLEX_STUDIO_DIR} must be replaced by C:/Program Files/IBM/ILOG/CPLEX_Studio1271 (in my case).

After this, follow the instruction given in https://www.r-bloggers.com/using-cplex-in-r-installing-cplexapi-in-windows-10/ , essentially use the following command (from command lines) to repackage and install cplexAPI_1.3.3.tar.gz (make sure you have Rtools installed, and make sure environment variables have PATH pointing to installation files of R, essentially taking to R.exe and Rcmd.exe for the commands to run), and

R CMD build --no-build-vignettes --no-manual --md5 C:\Users{computer name here}\Desktop\cplexAPI

R CMD INSTALL --build --no-multiarch .\cplexAPI_1.3.3.tar.gz

Answer 3

I have the exactly same problem and could not find a way to install the packages although tried everything similar to the post here. I am not sure if the problem is related to a version change in the CPLEX after the package is released.

Edit: I was able to confirm the problem. Apparently callable library elements addchannel, delchannel together with several others are removed in version 12.7. Here is the link:

http://www.ibm.com/support/knowledgecenter/SSSA5P_12.7.0/ilog.odms.cplex.help/CPLEX/ReleaseNotes/topics/releasenotes127/removed.html

In one of the package's source files, it has already been mentioned that "R Interface to C API of IBM ILOG CPLEX Version 12.1 to 12.6."

Looks like downgrading cplex will help.

GNU R package cplexAPI: R Interface to C API of IBM ILOG CPLEX

The installation procedure for the cplexAPI package needs to know where to find the CPLEX include directory and where to find the callable library.

I have a very large mixed integer problem to solve. COIN's solver accessed through Rsymphony did a decent job, but had trouble finding feasible solutions. I had been told that the IBM cplex solver was the best on the market for mixed integer programming.

Installing cplex is a relatively easy task. The difficulties began when I tried to install a link from R. Either cplexAPI or Rcplex. You can search and see that there is very little helpful information in the usual places. I reached out to the developers and Jonathan of cplexAPI responded with very helpful troubleshooting and instructions.

We (honestly, all Jonathan) determined that the following sequence should correctly install cplexAPI. First, read the directions.

1. After downloading, unpack the .tar.gz file someplace. I am going to unpack mine on the desktop.

2. Open the newly created folder cplexAPI and you will find a directory labeled src. Open the Makevars.win file within that folder. I have Notepad++ installed, so I right click Makevars.win and open withNotepad++. The instructions note that you will need to find each of these directories and type them in. They may (and probably will if you are using any other version).

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"C:/Program Files/IBM/ILOG/CPLEX_Studio127/cplex/include" PKG_LIBS=-L"C:/Program Files/IBM/ILOG/CPLEX_Studio127/cplex/bin/x64_win64" -lm -lcplex1270

After saving you will need to repackage cplexAPI. Head over to the command line (remember I unpacked my tar.gz file on my desktop) and use the command:

3.

a. goto C:\\Users{{your name here}}\\Documents\\R\\win-library\\3.5

b.create a new folder called cplexAPI

c. Create another folder inside cplexAPI called libs

d. Create another folder inside libs called x64

so, you have this folder C:\\Users{{your name here}}\\Documents\\R\\win-library\\3.5\\cplexAPI\\libs\\x64

The goto the installation folder for CPLEX application C:\\Program Files\\IBM\\ILOG\\CPLEX_Enterprise_Server1210\\CPLEX_Studio\\cplex\\bin\\x64_win64 and copy the file cplex12100.dll into the folder C:\\Users{{your name here}}\\Documents\\R\\win-library\\3.5\\cplexAPI\\libs\\x64

4. R CMD build --no-build-vignettes --no-manual --md5 C:\\Users{your name here}\\Desktop\\cplexAPI

This will repackage the folder, avoiding the md5 error you can find while searching for solutions. After a successful repackage you can then install the package at the command line.

5. R CMD INSTALL --build --no-multiarch .\\cplexAPI_1.3.3.tar.gz

At this point, you may have errors. The key you are looking for is this output:

packaged installation of 'cplexAPI' as cplexAPI_1.3.3.zip DONE (cplexAPI)

This procedure was tested successfully with IBM ILOG CPLEX 12.10
on 64-bit Windows 10 using Rtools 3.5.

Example:

library(cplexAPI)
 env <- openEnvCPLEX()
 prob <- initProbCPLEX(env)
 chgProbNameCPLEX(env, prob, "sample")
nc <- 3
 nr <- 3
 obj <- c(5, 4, 3)
 rhs <- c(5, 11, 8)
 sense <- rep("L", 3)
 lb <- rep(0, 3)
ub <- rep(CPX_INFBOUND, 3)
 cn <- c("x1", "x2", "x3")
 
rn <- c("q1", "q2", "q3")
beg <- c(0, 3, 6)

beg <- c(0, 3, 6)

 cnt <- rep(3, 3)
 ind <- c(0, 1, 2, 0, 1, 2, 0, 1, 2)
 val <- c(2, 4, 3, 3, 1, 4, 1, 2, 2)

copyLpwNamesCPLEX(env, prob, nc, nr, CPX_MAX, obj, rhs, sense, beg, cnt, ind, val, lb, ub, NULL, cn, rn)
lpoptCPLEX(env, prob)
 solutionCPLEX(env, prob)

Answer 5

It took me some time to figure it out, but here is my solution:

As user3575499 already pointed out, there is a good explanation on how to install cplexAPI at https://www.r-bloggers.com/2017/01/using-cplex-in-r-installing-cplexapi-in-windows-10/ .

However, after following those instructions, you might get the following error:

"C:\\Program Files\\IBM\\ILOG\\CPLEX_Studio_Community129\\cplex\\include/ilcplex/cpxconst.h:243:62: error: expected ')' before 'deprecated' # define CPXDEPRECATEDAPI(version) __declspec(dllimport deprecated)"

The solution to this error is to add "-DBUILD_CPXSTATIC" at the end of the first line of Makevars.win, so that the file looks something like this:

PKG_CPPFLAGS=-g -D_R_=1 -DUSE_R=1 -I"${CPLEX_STUDIO_DIR}\cplex\include" -DBUILD_CPXSTATIC
PKG_LIBS=-L"${CPLEX_STUDIO_LIB}" -lm -lcplex1261

After you changed that file just follow the instructions again and you should be fine.
