该目录中绝对有一个`cplex.h`文件！

Question

我正在尝试在R中使用cplexAPI。我遇到持久性错误。我正在使用Microsoft R Open 3.3.1并在Windows 10上安装了IBM ILOG CPLEX Optimization Studio版本：12.7.0.0。这是我所做的，以及由此产生的结果。希望你能在某个地方看到我的错误，我将详细介绍细节！

将tar文件解压缩到桌面上的文件夹中。
编辑文件：C:\Users\zejas\Desktop\cplexAPI\cplexAPI\src\Makevars.win说：

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

微软将自己的旋转放在Reviron.site文件上。他们将Rcmd_environ放入：C:\Program Files\Microsoft\MRO-3.3.1\etc\Rcmd_environ 在该文件中，我添加了最下面的三行：

## 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

在Environment Variables System Variables Path我已添加：

这些都是新错误！

Answer 1

对我来说，看起来你已经在Makevars.win文件中的路径前留下了$符号。请尝试更正：

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：正如baydoganm所指出的那样，cplex 1270中缺少两个函数。当删除它们时，cplexAPI也可以用windows编译： cplexAPI_1.3.3.tar.gz

Answer 2

我有完全相同的问题，但无法找到安装软件包的方法虽然尝试了类似于帖子的所有内容。我不确定问题是否与软件包发布后CPLEX中的版本更改有关。

编辑：我能够确认问题。在版本12.7中删除了显然可调用的库元素addchannel，delchannel和其他几个。这是链接：

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

在其中一个软件包的源文件中，已经提到过“与IBM ILOG CPLEX版本12.1到12.6的C API的R接口”。

看起来降级cplex会有所帮助。

Answer 3

GNU R 包 cplexAPI：IBM ILOG CPLEX 的 C API 的 R 接口

cplexAPI 包的安装过程需要知道在哪里找到 CPLEX 包含目录以及可调用库的位置。

我有一个非常大的混合整数问题要解决。通过 Rsymphony 访问的 COIN 求解器做得不错，但很难找到可行的解决方案。有人告诉我，IBM cplex 求解器是市场上最好的混合整数规划。

安装 cplex 是一项相对容易的任务。当我尝试从 R 安装链接时，困难就开始了。cplexAPI 或 Rcplex。你可以搜索一下，发现在平常的地方，有用的信息很少。我联系了开发人员，cplexAPI 的 Jonathan 给出了非常有用的故障排除和说明。

我们（老实说，所有 Jonathan）确定以下顺序应该正确安装 cplexAPI。首先，阅读说明。

下载后，将 .tar.gz 文件解压到某处。我要在桌面上打开我的包装。
打开新创建的文件夹cplexAPI，你会发现一个名为src的目录。打开该文件夹中的 Makevars.win 文件。我安装了 Notepad++，所以我右键单击 Makevars.win 并使用 Notepad++ 打开。说明指出，您需要找到这些目录中的每一个并输入它们。它们可能会（如果您使用任何其他版本，也可能会）。

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

保存后需要重新打包 cplexAPI。转到命令行（请记住，我在桌面上解压了 tar.gz 文件）并使用以下命令：

3.

一个。转到 C:\Users{{你的名字在这里}}\Documents\R\win-library\3.5

B.创建一个名为 cplexAPI 的新文件夹

c.在 cplexAPI 中创建另一个名为 libs 的文件夹

d。在 libs 中创建另一个名为 x64 的文件夹

所以，你有这个文件夹 C:\Users{{你的名字在这里}}\Documents\R\win-library\3.5\cplexAPI\libs\x64

转到 CPLEX 应用程序的安装文件夹 C:\Program Files\IBM\ILOG\CPLEX_Enterprise_Server1210\CPLEX_Studio\cplex\bin\x64_win64 并将文件 cplex12100.dll 复制到文件夹 C:\Users{{your name here} }\Documents\R\win-library\3.5\cplexAPI\libs\x64

R CMD build --no-build-vignettes --no-manual --md5 C:\Users{你的名字在这里}\Desktop\cplexAPI

这将重新打包文件夹，避免您在搜索解决方案时发现的 md5 错误。成功重新打包后，您可以在命令行安装该包。

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

此时，您可能有错误。您正在寻找的关键是这个输出：

'cplexAPI' 打包安装为 cplexAPI_1.3.3.zip 完成 (cplexAPI)

归功于 https://jholderieath.wordpress.com/2017/01/26/using-cplex-in-r-installing-cplexapi-in-windows-10/ https://github.com/cran/cplexAPI/blob/master/inst/INSTALL

此过程已使用 IBM ILOG CPLEX 12.10 成功测试
在使用 Rtools 3.5 的 64 位 Windows 10 上。

示例：

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)

在将CPLEX与R集成并安装cplexAPI软件包时，我遇到了类似的问题，请参阅https://cran.r-project.org/web/packages/cplexAPI/ 我正在做的错误很少，首先，问题出现是因为R不知道IBM CPLEX的安装位置，所以你必须手动更改cplexAPI_1.3.3.tar.gz包中的文件Makevars.win当您尝试从rstudio GUI安装cplexAPI时下载。寻找以下代码：

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

您需要检查的两件事是-L"${CPLEX_STUDIO_LIB}"在我的情况下被替换为-L"C:/Program Files/IBM/ILOG/CPLEX_Studio1271/cplex/bin/x64_win64"（请参阅bin / x64_win64），也请替换$

在文件夹x64_win64中第二个，查找cplex12**.dll文件，这是-lcplex1261指向的文件，这里手动将-lcplex1261更改为你的文件名（在我的例子中是cplex1271.dll，所以我将-lcplex1261更改为-lcplex1271，

同样${CPLEX_STUDIO_DIR}必须由C:/Program Files/IBM/ILOG/CPLEX_Studio1271替换（在我的情况下）。

在此之后，按照https://www.r-bloggers.com/using-cplex-in-r-installing-cplexapi-in-windows-10/中的说明进行操作，本质上使用以下命令（从命令行）重新打包并安装cplexAPI_1.3.3.tar.gz（确保安装了Rtools，并确保环境变量的PATH指向R的安装文件，主要是指R.exe和Rcmd.exe用于运行的命令）和

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 5

我花了一些时间才弄明白，但这是我的解决方案：

正如 user3575499 已经指出的，关于如何在 https://www.r-bloggers.com/2017/01/using-cplex-in-r-installing-cplexapi-in-windows-10/ 安装 cplexAPI 有一个很好的解释。

但是，按照这些说明操作后，您可能会收到以下错误：

"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) )"

解决这个错误的方法是在Makevars.win的第一行末尾添加“-DBUILD_CPXSTATIC”，使文件看起来像这样：

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

更改该文件后，只需再次按照说明操作即可。
