问题描述

我目前正在写在MATLAB中使用C中的CPLEX API来解决线性规划问题的MEX文件。不幸的是，我碰到一个符号（S）没有发现建筑x86_64的问题时，我试图编译我不知道如何解决它的主意。

一些基本信息：


  • 我可以编译 yprime.c 和不使用CPLEX API其他MEX文件

  • 我使用的是Mac OSX 10.7.2 MATLAB 2011B

  • 我使用包含以x code 4.2海合会4.2包。

  • 我已经申请了 X $ C $ 4.2Ç修补MATLAB

我将不胜AP preciate任何意见的人可能有。我下面包括一个详细的错误报告。

解决方案

您似乎缺少 -lcplex 或你的系统上CPLEX相关联的指令。

用户手册上说的正确包括和连接参数在你CPLEX分布readme.html文件，样本项目和makefile文件一起。

使用CPLEX用Matlab 该说你必须指定完整库链接路径和包含路径。根据你在做什么，你可能还需要指定 -lilocplex 来MEX。

例如。 MEX -I / cplex_include_fullpath -L / cplex_library_fullpath -lcplex file.c中

I'm currently writing a MEX file in MATLAB that uses the CPLEX API in C to solve linear programming problems. Unfortunately, I run into a "symbol(s) not found for architecture x86_64" problem when I attempt to compile and I have no idea of how to solve it.

Some basic information:

  • I can compile yprime.c and other MEX files that do not use the CPLEX API
  • I am using MATLAB 2011b on Mac OSX 10.7.2
  • I am using the GCC 4.2 package included in XCode 4.2.
  • I already applied the XCode 4.2 Patch for MATLAB

I would greatly appreciate any advice people may have. I'm including a verbose error report below.

解决方案

You seem to be missing -lcplex or the relevant linking instruction for cplex on your system.

The User manual says the correct include and linking parameters are in readme.html of your cplex distribution, along with sample projects and makefiles.

From Using Cplex with Matlab it says you have specify the full library linking path and include path. Depending on what you are doing you may need to also specify -lilocplex to mex.

E.g. mex -I/cplex_include_fullpath -L/cplex_library_fullpath -lcplex file.c
