Thanks Harbs, I am on windows, but did something similar with a windows batch file.
Instructions here [1] are also similar but include a couple of differences: 1. playerglobal seems to be required as 11.1. When I tried using a more recent playerglobal version as per those instructions I had to update the ant scripts which did not handle the more recent swfversion conversions in task "playerglobal-setswfversion" 2. Also mention the need to set GOOG-HOME envar. which I actually set to point inside my flex-asjs install, like so: set GOOG_HOME=%BASE_DIR%/flex-asjs/js/lib/google/closure-library I did not try without GOOG_HOME set, so not sure if it is absolutely required or not I finally got it to build, but not without making some changes.... It was breaking at the step when trying to build CoreJS.swc. Actually I am a bit confused here, because it seems that somewhere the script is changing the js-config.xml inside flex-asjs/frameworks by copying from js-config-template.xml. The updated js-config.xml inside frameworks now specifies a dependency on Core.swc see [2] (which does not yet exist) and is used to attempt to build CoreJS.swc which fails (Core.swc and others look to be built following the JS.swc versions in the frameworks ant script). I commented out this dependency <!--<path-element>libs/Core.swc</path-element>--> inside the 3 config.template.xml files that have that and the 'ant all' build then made it through to completion, so I am assuming/hoping all is well. This above issue may not be apparent to you if you are doing work on the isolated parts where the build scripts in the deeper directories do not change the configs, but I suspect it will be there for you if you did a full build. It's not the most encouraging experience for someone trying this for the first time, and I don't think I did anything wrong (although perhaps that is wrong!). Anyhow I think I might be set up to look into the BinaryData/ByteArray stuff now :) 1. https://github.com/apache/flex-asjs/blob/develop/READme 2. https://github.com/apache/flex-asjs/blob/develop/frameworks/js-config-template.xml#L73 On Thu, Jul 14, 2016 at 8:59 PM, Harbs <[email protected]> wrote: > Monkey patching does not work very well. > > Here’s my setup (on Mac — Windows is similar): > > 1) Follow the instructions here to get your basic environment setup: > https://cwiki.apache.org/confluence/display/FLEX/FlexJS+Developer+Setup > > 2) If you want to use Flash Builder, read the section on Flash Builder on > the above page and this as well: > https://cwiki.apache.org/confluence/display/FLEX/Using+FlexJS+with+Adobe+Flash+Builder > > 3) I have a shell script to set all my environment variables in each shell > like this: > #!/bin/sh > > export FALCON_HOME=/Users/harbs/Documents/ApacheFlex/flex-falcon/compiler > export FLEXUNIT_HOME=/Users/harbs/Documents/ApacheFlex/flex-flexunit > export FLEX_HOME=/Users/harbs/Documents/ApacheFlex/flex-sdk > export > AIR_HOME=/Users/harbs/Documents/ApacheFlex/frameworks/AIRSDK_Compiler > export > PLAYERGLOBAL_HOME=/Users/harbs/Documents/ApacheFlex/frameworks/libs/player > export > FLASHPLAYER_DEBUGGER=/Users/harbs/Documents/ApacheFlex/frameworks/Flash\ > Player\ Debugger.app/Contents/MacOS/Flash\ Player\ Debugger > export FLEXJS_HOME=/Users/harbs/Documents/ApacheFlex/flex-asjs > > 4) You can then run ant on either flex-asjs or any one of the individual > Projects such as Core.
