• Component: New Bugs
• Status: RESOLVED FIXED

[Zoltan Arvai]

After r149944 Qt Win build is failing:

C:\buildslave\qt-windows-32bit-release\build\Source\WebKit2\Platform\CoreIPC\ArgumentEncoder.cpp(51) : error C3861: 'munmap': identifier not found
C:\buildslave\qt-windows-32bit-release\build\Source\WebKit2\Platform\CoreIPC\ArgumentEncoder.cpp(75) : error C2065: 'PROT_READ' : undeclared identifier

C:\buildslave\qt-windows-32bit-release\build\Source\WebKit2\Platform\CoreIPC\ArgumentEncoder.cpp(82) : error C3861: 'munmap': identifier not found

And after r149945:

C:\buildslave\qt-windows-32bit-release\build\Source\WebKit2\Platform\CoreIPC\ArgumentEncoder.cpp(32) : fatal error C1083: Cannot open include file: 'sys/mman.h': No such file or directory

Can you check it, please?

Zoltán, Apple isn't responsible to fix any Qt-WK2 related build 
breakages. So it would be great if you can check and fix it yourself 
instead of asking others to do it. ;-)

I found similar things in WTF/wtf/TCSystemAlloc.cpp where #if guards are used for MMAP and VIRTUALALLOC capable ports.

There’s no reason to call VirtualAlloc/VirtualFree on Windows; you can keep calling malloc/free.

Use fastAlloc instead of VirtualAlloc and use mmap only on OS(DARWIN).
