Brief instructions for working with Chimera in Windows. 1) Download and install Visual C++ 2005 Express Edition (http://msdn.microsoft.com/vstudio/express/visualc/) 2) Download and install the Microsoft Platform SDK (http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/) 3) Unpack the ZIP file containing the Windows version of Chimera into a directory of your choice 4) Double click on Chimera.sln; this will open the Chimera solution inside Visual C++ 5) Click on the Visual C++ build solution button; this will generate Chimera.lib in Debug or Release form, depending on your Visual C++ settings. I recommend using the Release settings since a Debug library has dependencies with Visual C++ DLLs. 6) There are two external libraries needed in chimera win32. One is the PThread library. You can download the library file from: http://sources.redhat.com/pthreads-win32/ Note that it is an open-source distribution. PThread has several kinds of libraries, due to the ANSI C code style used in the original chimera, please choose pthreadVC2.lib and pthreadVC2.dll in linking and running, respectively. The suffix VC represents Microsoft Visual Studio and ANSI C (no exceptions - using setjmp/longjmp). The other library needed is OpenSSL library. You can download the library file from: http://209.61.202.80/apache/Openssl-0.9.8b-Win32.zip The file libeay32.lib is used for linking and libeay32.dll is used for running. 7) In addition, please check whether wsock32.lib is put in the linking references. In Visual Studio's default, it is not included.
