Problems building QT x86 libraries from source with Visual Studio 2017 (15.8.3) and QT 5.11.1

CAM79

Hi,

I've just rebuilt my PC and installed the latest Visual Studio 2017 (15.8) and download the latest QT 5.11.1 source via the website.

I'm in need of the 2017 32-bit libraries which do not ship. I understand that the 2015 libraries would be compatible but this should build.

So, there are two issues, the first of which can be fixed by adding -D_ENABLE_EXTENDED_ALIGNED_STORAGE to CFLAGS_BARE in Makefile.win32.

The second issue relates to "auto_ptr" not being part of 'std'. There are numerous suggestions on how to fix this, one being to remove:

QMAKE_CXXFLAGS_CXX1Z = -std:c++17

from msvc-version.conf, or change to:

QMAKE_CXXFLAGS_CXX1Z = -std:c++1z

but neither of these work.

Do you have any suggestions?

My build looks like this:

x86 Native Tools Command Prompt for VS 2017
Compiler: Microsoft (R) C/C++ Optimizing Compiler Version 19.15.26726 for x86
configure -prefix %CD%\qtbase -debug-and-release -nomake examples -nomake tests -opensource
nmake

Then to clean for next build:

nmake clean
Delete Makefiles from \Src, \Src\qtbase\qmake

Many thanks in advance.

Hi @CAM79,

The first problem is fixed for Qt 5.11.2 already so at least updating to 5.11.2 will help when this is released in that respect. As for the auto_ptr issue I have not heard of this one being a problem with MSVC so far. What is the error message you are seeing there?

Hi Andy,

Seems to be the same as this but building the x86 version:

https://bugreports.qt.io/browse/QTBUG-68954

error C2039: 'auto_ptr': is not a member of 'std' in
qtbase\src\3rdparty\angle\src\compiler\preprocessor\MacroExpander.h

Unfortunately, none of the suggestions in that bug report helped me.

I found a workaround for the minute is to change the auto_ptr to uniqute_ptr in MacroExpander.h, it now compiles.

Thanks,

Brent.
