Overlap between Objective-C and MATLAB/Octave file extensions

Do Objective-C or MATLAB/Octave have source file extensions besides .m? I ask because I'm putting Hello World programs in a single folder and I can't have two hello.m files.

A workaround would be to use .mm for Objective-C. .mm is used for Objective-C++ source files and it is a superset of Objective-C so it should compile fine.

This is by no mean a clean solution. A much better way would be to reorganize your folder into subfolders as suggested by Ruddy Velthuis, or simply to call your source files hello-objective-c.m and hello-matlab.m.

The only way I see is to create subdirectories for each of the programs and put your files there. You can tell Obj-C to treat other extensions as Obj-C, but that would not solve the problem for the other programs.

Update

To compile any extension as Objective-C, use -x objective-c on the command line or Select Objective-C from "Compile Sources As" in the target build settings. Default is "According To File Type", which means that only .m files are compield as Objective-C.

FWIW, there are many subtle differences between Objective-C++ and Objective-C. I myself would use subfolders to separate the .m files, as I already said above.

MATLAB cannot find files unless they have the .m extension (very important!)

Now I know very little about Objective-C, I presume it's a superset of C (just like C++ is). If so, and similar to C/C++, you should be able to pass any file name as input to the compiler:

g++ -c myfile.m.txt
