Both files should be in an identical folder.Īfter running "compile.m", you should be able to see the output message "From C : Hello world!" in the Matlab command window. ![]() In the following files, you can try to build a test mex function. This should give you the following output: MEX configured to use 'MinGW64 Compiler (C )' for C language compilation. ► Choose the destination folder for installation (in my case "C:\mingw-w64\x86_64-5.3.0-posix-seh-rt_v4-rev0") and go to next steps.Īfter installation, to inform the path of the compiler to Matlab, you can write in Matlab command-window, or directly in your m-file the following command. ► Select the proper version (5.3.0) and architecture (in my case "x86_64"). ► Download and run mingw-w64 installer file -> link: mingw-w64-install.exe In Matlab R2017a, it gives you the following output: MEX configured to use 'MinGW64 Compiler (C )' for C language compilation. To test whether the compiler is set correctly, type the following command in the Matlab Command Window mex -setup C ![]() Replace the given default installation path of the compiler, if you changed it. Now, to inform the path of the compiler to Matlab, you can write in Matlab command-window, or directly in your m-file the following command. I would suggest the procedure in Compiling mex files with Visual Studio to compile mex-files directly into Visual Studio. ► In front of gcc section, make sure that the correct version 4.9.2 is given if not, you probably forgot to uncheck updates in the beginning. ► If you are going to write programs with parallel computations, make sure to check OpenMP in optional components - gcc. ► Uncheck box "Check for updated files on the TDM-GCC server". ► Download the compiler binary file -> link: tdm64-gcc-4.9.2-3.exe only for creating Simulink S-Functions using the MATLAB MEX command. ![]() Instructions are given below for both categories. Installing compiler (GCC) for host (WINDOWS) How to install gcc in windows First. ◼ For Matlab R2017b, MinGW 5.3 is required. ◼ For Matlab R2015b up to R2017a, you can use MinGW 4.9.2 TDM-GCC.
