Will, did you follow the build instructions on the Wiki page? http://wiki.openlaszlo.org/SubversionBuildInstructions
If you build OpenLaszlo 4.9, you need to use a different version of the JavaCC parser, version 2.1. Maybe that's causing the strange error method on your machine. Which version of javacc do you have installed? For my 4.9 build, I get: $:~/src/svn/vendor$ javacc -version Java Compiler Compiler Version 2.1 (Parser Generator) If you have javacc 5.0 installed, do the following steps. Go into $LZ_VENDOR_ROOT, and update to revision 16963 as shown here. This will restore the JavaCC 2.1 version in the vendor folder. Then launch the installer, and install the 2.1 version. Add the javacc2.1/bin folder to your path. If that doesn't resolve the problem, I can only recommend that you build in Linux instead. $:~/src/svn/vendor$ svn update -r 16963 D javacc-5.0.zip A JavaCC2_1.class Updated to revision 16963. $:~/src/svn/vendor$ java JavaCC2_1 WebGain Installer Copyright 1997-2001 WebGain Inc. ... (now install JavaCC 2.1 using the GUI installer) - Raju
