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
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
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
