Notes for Old Closure Compiler

Old build instructions for Standalone Engine

Node dependencies you have to install:

 closure
 closure-compiler
 closure-library
 xmldom
 xpath
 commander
 xml-mapping

Using npm run

 npm install closure closure-compiler closure-library xmldom xpath commander xml-mapping

In version 1.43 of the closure library there is a mistake in the file

closure-library/closure/bin/build/jscompiler.py 

You might need to change

# Attempt 32-bit mode if we're <= Java 1.7
if java_version >= 1.7:
  args += ['-d32']

to

# Attempt 32-bit mode if we're <= Java 1.7
if java_version <= 1.7:
  args += ['-d32']

Cleaning up the old closure version

clean_closure: clean_compiler clean_import_script

clean_compiler:
@sed -i s/\'-d32\'//g $(CLOSURE_ROOT)/jscompiler.py

clean_import_script:
@sed -i s/'goog.global.CLOSURE_IMPORT_SCRIPT\;'/'goog.global.CLOSURE_IMPORT_SCRIPT = null\;'/g $(CLOSURE_LIB)/closure/goog/base.js

Creating link in the Makefile

CLOSURE_LIB_LINK = $(SRC_DIR)/$(CLOSURE_LIB_NAME)

link: $(CLOSURE_LIB_LINK)

$(CLOSURE_LIB_LINK): 
@echo "Making link..."
@ln -s $(CLOSURE_LIB) $(CLOSURE_LIB_LINK)
