Question

我正在尝试在MATLAB中编译Mex文件this example，该文件使用C语言中的CPLEX API来解决线性编程问题。不幸的是，我收到了这个错误：

mex - I/..../Applications/IBM/ILOG/CPLEX_Studio1271/cplex/include/ilcplex -

 64_osx/static_pic -lcplex lp_cplex_mex.c

 Error using mex
 Undefined symbols for architecture x86_64:
 "_CPXgetitc", referenced from:
  _mexFunction in lp_cplex_mex.o
 (maybe you meant: _CPXgetitcnt)
 "_CPXopenCPLEXdevelop", referenced from:
  _mexFunction in lp_cplex_mex.o
 ld: symbol(s) not found for architecture x86_64
 clang: error: linker command failed with exit code 1 (use -v to see 
 invocation)

一些基本信息：

我可以编译yprime.c和其他不使用CPLEX的MEX文件 API
我在Mac OSX El Capitan 10.11.16上使用MATLAB 2015a
我正在使用XCode 8.2中包含的GCC包

我想我的问题是库，它可以找到文件夹但内部有问题，有.../cplex/lib/x86-64_osx/static_pic文件的内容：

libilocplex.a
libcplexdistmip.a
libcplex.a

我认为我们应该有.so扩展名的文件，我非常感谢大家提出的任何建议。

在Mac OSX上使用Cplex和Matlab的Mex文件“找不到架构x86_64的符号”
