Building QT5 webengine - C++11 support is required error

[Nahash]

Hello everyone,

I've been trying to build QT's webengine from source lately and have been continuously running into problems. QT will build everything except webengine (the module I actually want) successfully. When it gets to webengine, jom (and nmake) report "C++11 support is required in order to build chromium. QtWebEngine will not be built."

I've downloaded and gone through the depot_tools for chromium, made sure I'm on the dev branch, I'm running MSVC 2013 community edition, I've made sure that windows 8 sdk and windows 7.1 driver kit is installed, I've set all of the PATH components and the WDK_DIR env variables, I've even dug into the source code to see what is triggering the check and then manually entered QT_CONFIG+= C++11into the pro files figuring it was missing somewhere. Still, the build process complains that I do not have c++11 support. Anyone have any suggestions on what else to try?

Configure settings: -nomake tests -nomake examples -confirm-license -opensource -opengl es2 -angle -debug -c++11

(I've tried -debug-and-release and -prefix before as well but read in the past that both of those had issues with webengine)

Environment: Clean Windows 7 VM
MSVC 2013 community edition
Python 2.7.6
Perl 5.20.1

I use the following in my .pro files for C++11 support:

@QMAKE_CXXFLAGS = -std=c++11
CONFIG += c++11@

I have no idea if this has anything to do with your specific problem thou...

[/quote]If you write Line #2, then you don't need Line #1 anymore.

Nope, have both of those set in qtwebengine.pro with the error still occurring unfortunately (and set in the file for qt_build_config as well, for good measure)

I'm afraid I don't have experience with building Qt WebEngine. Have you tried going through "this article":http://qt-project.org/wiki/QtWebEngineOnWindows ? You probably don't need to check out from git since you already have the source code.

That's the article I've been following. Everything works fine up until the build stage and then the c++11 support error doesn't let webengine build.

Try asking at the "Interest mailing list":http://lists.qt-project.org/mailman/listinfo/interest (you need to subscribe first). Qt engineers are active there, and they probably know more.
