make command does not work when trying to compile Pepper.js on MS Windows

[briangavin]

If you try to make the Pepper.js files on MS Windows you get a build error when trying to compile the release version of emscripten. The debug version seems to work properly.

make TOOLCHAIN=emscripten CONFIG=Release

It appears to be a problem with copying finished .js file uses 'cp' should be 'copy'?

I'm not quite sure about the cause of this issue, but I think that you can work around it my changing command line for the make command from

make TOOLCHAIN=emscripten CONFIG=Release

to

make TOOLCHAIN=emscripten CONFIG=release

Note that the CONFIG value is release not Release. On my Windows 7 machine I was getting the following error with the former command line, but the latter command line seems to work:

undefined:1

The bug is still there even with 'release' instead of Release. cp command is being used for copy should be copy on Windows.

Note -
make TOOLCHAIN=emscripten CONFIG=Debug works correctly.

error -
make: *** [ppapi_cpp_TARGET ] Error 2

Ok, sorry. I must have been facing a different problem then.
