Bug 89374 – stdint.h installed for windows causes errors when compiling with MSVC for x64

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Alex Christensen]

When compiling JavaScriptCore for a 64-bit machine with MSVC, WebKitLibraries\win\include\stdint.h causes compile errors.  I suggest lines 56-58 be changed from 

/* 7.18.1.4  Integer types capable of holding object pointers */
typedef int intptr_t;
typedef unsigned uintptr_t;

to this:

/* 7.18.1.4  Integer types capable of holding object pointers */
typedef ptrdiff_t intptr_t;
typedef size_t uintptr_t;

This change works for 32 bit and 64 bit machines.  This is not a part of the repository (it's installed with the script update-webkit --wincairo), so I cannot submit a patch.

wincairo should use http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/os-win32/stdint.h instead. If that file does not work, a bug is ok. But for the wincairo files you should talk to Brent in the github repository at https://github.com/bfulgham/WinCairoRequirements, since they are not part of WebKit directly.

I uploaded a new WinCairoRequirements bundle that addresses this issue.  This isn't a WebKit bug, but rather a build environment problem.

Running "update-webkit --wincairo" should give you the new headers/binaries/link libraries.

Note that I do not provide 64-bit builds in this bundle at present.
