Notes about building JavaScriptCore on Win32: The build has been tested with Visual Studio 2003 (7.1) and Visual Studio 2005 Beta 2. It should also work with Microsft's free http://msdn.microsoft.com/visualc/vctoolkit2003 (which is basically the same compiler & linker that is a part of VS 2003 but without the IDE) but it has not been tested. It doesn't build with VS 6. To build: * make sure that the tools are in the path. VS comes with vcvars32.bat batch file somewhere under installation directory which sets all the proper env variables. I usually rename it to e.g. vc7.bat and put in my %PATH% for easy invocation) * you need to download ICU (http://www-306.ibm.com/software/globalization/icu/index.jsp) pre-built DLLs and header files. I've tested it with VS 7.1 (ftp://ftp.software.ibm.com/software/globalization/icu/3.4/icu-3.4-Win32-msvc7.1.zip) Set ICUDIR to where you've downloaded the files. * you need perl for generating *.lut.h files * you need bison for generating parser from grammar.y (I use http://gnuwin32.sourceforge.net/packages/bison.htm) * nmake -f Makefile.vc clean * nmake -f Makefile.vc or * nmake -f Makefile.vc DEBUG=1 What do you get: in bin subdirectory you'll find testkjs.exe executable which is a javascript interpreter. It can be used to run javascript tests in tests\mozilla (see \WebKitTools\scripts\run-javascriptcore-tests for an example on how to run them; you can use this script if you just replace "testkjs" with a full path to testkjs.exe. TODO Currently only testkjs.exe is built. It should also build a static .lib library so that it's easy to build programs incorporating the core. It should also build as a dynamic DLL. It's just a matter of fiddling with the makefile.
