emcc not support makefile in my mac

[龚楷楠]

I am trying to run a sample emscripten code downloaded from https://github.com/pbcostello/ems1

Typing

emcc main.cpp -o main.js -s EXPORTED_FUNCTIONS=['_getSqrt','_getStringLength']

can result in the main.js file generated successfully.

But typing 

emcc makefile

result in such error messages:

ERROR    root: makefile: Input file has an unknown suffix, don't know what to do with it!

Even I created a new empty makefile and type emcc makefile, the same error appears.

So I guess emcc command can't parse makefile files?

Or do I type a wrong command?

My emcc version is:

emcc (Emscripten GCC-like replacement + linker emulating GNU ld ) 1.29.0

clang version 3.4 

Target: x86_64-apple-darwin13.4.0

Thread model: posix

INFO     root: (Emscripten: Running sanity checks)

Thank you

You want em++ for c++.

Also you want to use emmake, not emcc, for the makefile.

Thanks a lot for your quick reply.

emmake does work.
