Description Zoltan Arvai 2013-05-22 06:45:18 PDT
After the patch something went wrong on Qt Mips:

/data/buildbot/mips-1/qt-linux-mipsel-mips32r2-release/build/Source/WebKit2/UIProcess/Plugins/PluginProcessManager.cpp: In member function 'WebKit::PluginProcessProxy* WebKit::PluginProcessManager::getOrCreatePluginProcess(uint64_t)':
/data/buildbot/mips-1/qt-linux-mipsel-mips32r2-release/build/Source/WebKit2/UIProcess/Plugins/PluginProcessManager.cpp:126: error: cannot convert 'std::nullptr_t' to 'WebKit::PluginProcessProxy*' in return
make[3]: *** [.obj/release-shared/UIProcess/Plugins/PluginProcessManager.o] Error 1

It seems WTF_COMPILER_SUPPORTS_CXX_NULLPTR isn't defined in
Source/WTF/wtf/Compiler.h , because you use too old compiler.

But now c++11 is mandatory for WebKit2, so you probably need newer compiler.

Sorry, I wanted to write: Thank you

The compiler support most of C++11, but is 'nullptr' really necessary? We can replace it with a 0, and it would work.

C++11 in WebKit2 is mandatory now... 

... but feel free to find a WebKit2 owner for this fix. :)

All of C++11 is hardly mandatory, or we would depend on unreleased compilers. There is has to be an expected subset of featuers.

I’ve generally only used features that’s available on compilers that have been out for at least two years. That includes MSVC 2010 as well as GCC 4.6.
