Matlab Mex命令中的Cplex链接错误

Question

I am trying to run mixed integer quadratic programming by calling Cplex (122version) from Matlab using Mex function. When I try in matlab : mex miqp_cplex.c, following type errors occurred.

Creating library C:\\Users\\maskamal\\AppData\\Local\\Temp\\mex_3XVWAG\\templib.x and object C:\\Users\\maskamal\\AppData\\Local\\Temp\\mex_3XVWAG\\templib.exp miqp_cplex.obj : error LNK2019: unresolved external symbol __imp_CPXcloseCPLEX referenced in function miqp miqp_cplex.obj : error LNK2019: unresolved external symbol __imp_CPXfreeprob referenced in function miqp miqp_cplex.obj : error LNK2019: unresolved external symbol __imp_CPXgetmipitcnt referenced in function miqp miqp_cplex.mexw64 : fatal error LNK1120: 21 unresolved externals

C:\\PROGRA~1\\MATLAB\\R2011A\\BIN\\MEX.PL: Error: Link of 'miqp_cplex.mexw64' failed.

Since it fail to locate "ilcplex\\cplex.h", I add full path

include "C:\\ILOG\\CPLEX_Studio_AcademicResearch122\\cplex\\include\\ilcplex\\cplex.h" and I guess problem is related to cplex.h and linking with library.

Any hints to solve my problem are welcomed.

I could solve it partly. I could compile by adding the path of library with mex command. However, when I run the mex file: miqp_cplex it says: Invalid MEX-file 'C:\\Users\\maskamal\\Documents\\MATLAB\\MexCplex80\\miqp_cplex.mexw64': 指定されたモジュールが見つかりません。(translation from japanese: indicated module is not found)
