Emscripten --pre-js

I am trying to use Urho3D with emscripten.
/home/dares/emsdk/upstream/emscripten/emcmake cmake .
worked without any Problems.
but the next step doesnt work :frowning:
/home/Dares/emsdk/upstream/emscripten/emmake make
reaches 90% but then comes :

em++: error: ‘–pre-js’: file not found: ‘/src/emrun_prejs.js’
make[2]: *** [Source/Tools/Urho3DPlayer/CMakeFiles/Urho3DPlayer.dir/build.make:90: bin/Urho3DPlayer.html] Fehler 1
make[2]: Verzeichnis „/home/dares/Schreibtisch/UrhoEm/Urho3D“ wird verlassen
make[1]: *** [CMakeFiles/Makefile2:2419: Source/Tools/Urho3DPlayer/CMakeFiles/Urho3DPlayer.dir/all] Fehler 2
make[1]: Verzeichnis „/home/dares/Schreibtisch/UrhoEm/Urho3D“ wird verlassen
make: *** [Makefile:152: all] Fehler 2
emmake: error: ‘make’ failed (2)

what am I doing wrong?

Did you try ./script/cmake_emscripten.shיbat? It will ask you to set the EMSCRIPTEN_ROOT_PATH environment variable, if you haven’t. On Linux: export EMSCRIPTEN_ROOT_PATH=~/emsdk/upstream/emscripten should fix that, in your case. Adding the line to ~/.bashrc will set it automatically in the future.
