The instructions below refer to building the REXX Interpreter (DLL or dylib) for ZOC V6. ZOCREXX.DLL is based on REGINA.DLL (http://regina-rexx.sourceforge.net/) with a GNU LGPL license (COPYING_LIB.TXT). Building ZOCREXX.DLL Windows (VS2005) from the source folder (regina-3.4-zoc) - start a VisualC 2005 command shell - cd build - build Debug version with mkdebug.cmd - build Release version with mkrelease.cmd - copy Release\zocrexx.dll to c:\program files\zoc6 Building zocrexx.dylib for OS X (10.4 Tiger, XCode 2.4) from the source folder (regina-3.4-zoc) - cd regina-3.4-zoc - make - copy zocrexx.dylib to zoc6.app\Contents\Frameworks Creating the Windows Source Folder from Scratch: - adjust rexxsaa.c and .def file (use .diff file) copy win32_dll.vc makefile from build to Regina-x.x-zoc cd build debug.cmd to build debug version (copy to w:\zoc6\reginal\binaries\win32\debug) ndebug.cmd to build relase version (copy to w:\zoc6\reginal\binaries\win32\relase) Darwin: - ./configure change source (rexxsaa.c ... see diff) change Makefile (see diff) make
