I was trying to use NLOPT ( https://nlopt.readthedocs.io/en/latest/ ) on Matlab (Windows system) following the instruction https://nlopt.readthedocs.io/en/latest/NLopt_on_Windows/.After generating the lib file from dll, I tried
mex -v nlopt_optimize.c libnlopt-0.lib
and got the error message
Verbose mode is on.
Neither -compatibleArrayDims nor -largeArrayDims is selected.
Using -compatibleArrayDims. In the future, MATLAB will require the use of
-largeArrayDims and remove the -compatibleArrayDims option.

I'm pretty sure that all the files are in the same folder, and have no idea what was happening. I would really appreciate it if anyone can help. THX.
(I use MinGW64 as the Compiler (C). )

Hi Zhujun,
If you've solved the problem, would you mind sharing the file?
Thanks

I had the same error, but here is what I did to build successfully on 64 bit Windows 10 machine.
  • I downloaded the 64bit version of the zip file from https://nlopt.readthedocs.io/en/latest/NLopt_on_Windows/
  • After it downloaded, I unzipped to C:\Users\someFilePath\nlopt
  • I opened "Developer Command Prompt for VS 2017" and I changed the directory to C:\Users\someFilePath\nlopt
  • In the command prompt, I ran this code:
lib /def:libnlopt-0.def /machine:x64
  • The command above created a libnlopt-0.lib file.
  • Then I successfully built using the follwing lines of MATLAB code:
% chage directory
cd('C:\Users\someFilePath\nlopt');
% add the files to the search directory
addpath(genpath('C:\Users\someFilePath\nlopt'));
% build, link to header and link to .lib file (no space between -I, -L, and -l)
mex .\matlab\nlopt_optimize.c -IC:\Users\someFilePath\nlopt -LC:\Users\someFilePath\nlopt -llibnlopt-0

Unless all of the source C files are explicitly #include in your nlopt_optimize.c file, you must list them explicitly in the mex command. E.g., if there are multiple C source files you would need to do this:
mex -v nlopt_optimize.c another_source1.c another_source2.c libnlopt-0.lib
That is, if another_source1.c and another_source2.c are needed but not explicitly #include in the nlopt_optimize.c file, you have to list them manually in the mex command.

Hi James, thx for your answer, but I have only one .c file (nlopt_optimize.c), the others are
libnlopt-0.lib
libnlopt-0.dll
libnlopt-0.def
nlopt.h
nlopt.f
nlopt.hpp
