[Laszlo-dev] Compiling laszlo

[P T Withington]

The instructions for rebuilding the LFC are here:

   http://wiki.openlaszlo.org/SubversionBuildInstructions

The top-level build target is

   ant make

This will recompile any changes and re-install the server in tomcat.

If you have set up that environment and want to quickly build a test  
lfc for a particular back-end, you need to be in the directory

   WEB-INF/lps/lfc

In there are shell scripts for invoking the correct ant procedure to  
build.  Note that there is a separate script for building the non- 
debug, debug, and backtrace-enabled LFC, unfortunately.  It is easy to  
confuse yourself by building one version and testing another.  Also,  
you may have to use your browser's debugger to empty its cache and  
force it to reload the LFC.  These are the scripts:

   ./buildlfc
   ./buildlfcdebug
   ./buildlfcbacktrace

The all take a --runtime option.  To build the swf9 debug runtime, you  
would say:

   ./buildlfc --runtime=swf9

There is no bactracing in swf9 (yet).  But the wiki article above  
tells how to get the Flash debug player and use fdb to debug swf9 code.

If you are debugging generic code (not code for a particular  
platform), you may find it easier to debug using the DHTML runtime  
which has built-in backtracing and which you can use the browser  
debugger (e.g., Firebug for Firefox) to do low-level debugging with.

We hope you will consider contributing your fixes back!
