I'm trying to Compile a Mex file, this example, in MATLAB that uses the CPLEX API in C to solve linear programming problems. Unfortunately, I get this error :

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)
Some basic information:
I can compile yprime.c and other MEX files that do not use the CPLEX API
I am using MATLAB 2015a on Mac OSX El Capitan 10.11.16
I am using the GCC package included in XCode 8.2
I guess my problem is with library, it can find the folder but something wrong inside, There is the content of .../cplex/lib/x86-64_osx/static_pic file:
- libilocplex.a
- libcplexdistmip.a
- libcplex.a
I think we should have files with .so extension, I would greatly appreciate any advice people may have.
