-*How to set up Blockly*
+====== How to set up Blockly ======
 This is more a maintaince handbook for the OOBD team themself as anything the normal developer need to be worried about, so just forget this page
-Download the [[http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html#sdk-downloads|emscripten- Package]] and install in ~/bin by following the instructions. Make sure to install the other listed programs (cmake,nodejs,..)  first (clang and llvm is not listed as needed,please install this too)
-Install your own llvm version, as the original ubuntu version is not build with javascript support
+===== Install emscripten =====
+Under Ubuntu 14.04 that's easy: Just install
+  sudo apt-get install emscripten
+===== Compile Luac as javascript binary =====
+Download the actual lua archive (http://www.lua.org/ftp/). Keep in mind that OOBD (actual) still uses the older lua 5.1 system. Unpack the archive and do some modifications in the make files:
+in main Makefile, add a new target (emcc):
+  # Convenience platforms targets.
+  PLATS= aix ansi bsd freebsd generic linux macosx mingw posix solaris emcc
+In scr/Makefile
+replace the gcc compiler against emcc
+  CC= emcc
+comment the LIBS directive, as it seems not to be used and creates a warning
+  # LIBS= -lm $(MYLIBS)
+creates a new target with only luac, but without lua itself
+  ALL_C= $(LUA_A) $(LUAC_T)
+  comp:   $(ALL_C)
+Add the new defined target as emcc build target
+  emcc:
+        $(MAKE) comp MYCFLAGS=-DLUA_USE_POSIX
+Start the build process
+  emmake make emcc
+change into the source dir
+  cd src/
+build luac.js
+  emcc -o luac.js  luac.o print.o liblua.a
-svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
+test it
+  nodejs luac.js
+build html wrapper
+  emcc -o luac.html  luac.o print.o liblua.a
+and load it via local webserver (''php -S localhost:8000'') into browser for testing
