[KuznetsovVN]

I try to build a dosbox.js file. Platform of my PC is Ubuntu_14.04.02_x64.
I write in the console next:

1. git clone https://github.com/dreamlayers/em-dosbox.git

   done

2. cd em-dosbox

   done

3. sudo ./autogen.sh

   done. Now you are ready to run ./configure

4. sudo emconfigure ./configure

   done

5. sudo make

   errors, the result below:

What did I do wrong?

This seems to be the problem:

sdlmain.cpp:2022:4: error: use of undeclared identifier

What version of Emscripten are you using? The one available as a package in Ubuntu is old, and you need to install it using the Emscripten instructions: https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html

Hello, thanks for response.

In my case i used the UBUNTU 15.10
I was install emscripten (by documentation in https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html) and it was successful.
Next, i write to terminal:
./autogen.sh
emconfigure ./configure
make

and in SRC folder was created a dosbox file, it executable (application/x-executable) file.
I was expected javascript file (((

I newest in programming for UNIX platforms, and I don't know where is wrong.
