There are 3 main issues.</div><div><br></div><div>1.) The typical 64bit hackery you have to do with VC++2010 since it refuses to play nicely out of the box unless you install Windows SDK7.1 and choose the Platform Toolset under the Property Pages to be "Windows7.1SDK".</div>
<div>2.) Add the following modification to gzguts.h</div><div><br></div><div>Before:</div><div><br></div><div>#ifdef __TURBOC__</div><div><div># include <io.h></div><div>#endif</div></div><div><br></div><div>After:</div>
<div><br></div><div><div>#if defined(__TURBOC__) || (defined(_MSC_VER) && _MSC_VER >= 1600)</div><div># include <io.h></div><div>#endif</div></div><div><br></div><div>since otherwise VC10 does not correctly pick up the open, write, close and 64bit seeki functions.</div>
<div><br></div><div>3.) Now I'm up to the stage where the "testzlib" project under the main zlibvc solution complains of "error LNK2001: unresolved external symbol gzflags" which I am currently working on.</div>
<div><br></div><div>4.) Aside from this the dll targets complain of:</div><div><br></div><div><div>1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppBuild.targets(990,5): warning MSB8012: TargetPath(C:\Users\luke.emrose\Documents\LukeDev\zlib-1.2.6\contrib\vstudio\vc10\x64\ZlibDllRelease\zlibvc.dll) does not match the Linker's OutputFile property value (C:\Users\luke.emrose\Documents\LukeDev\zlib-1.2.6\contrib\vstudio\vc10\x64\ZlibDllRelease\zlibwapi.dll).
