Dear Sir, I have built the JavaScriptCore.dll using Cygwin. Now I am trying to build my browser application which uses this dll and lib using Visual Studio 2005. I am getting number of errors. Following errors occur in most of the file repeatedly : 1. javascriptcore\runtime\jswrapperobject.h(45) : error C2027: use of undefined type 'JSC::JSObject' 2. javascriptcore\runtime\jswrapperobject.h(31) : error C2504: 'JSC::JSObject' : base class undefined 3. javascriptcore\jit\executableallocator.h(77) : error C2589: '(' : illegal token on right side of '::' 4. javascriptcore\runtime\dateinstancecache.h(49) : error C2079: 'JSC::DateInstanceData::m_cachedGregorianDateTime' uses undefined struct 'JSC::GregorianDateTime' For the first error, I have found that it's a known issue with Visual Studio (Ref : http://social.msdn.microsoft.com/Forums/en/vclanguage/thread/02aaef70-8a92-4... ). I have following queries: 1. Can we build Squirrelfish files using visual studio 2005? 2. If yes, Please provide us with steps (links). We urgently need these clarification to go ahead for our project work. Awaiting Reply. Thanks and Regards, Dipak Kumar
