使用Visual Studio 2013为WinRT构建Qt

Question

I downloaded the Qt for Windows Runtime Technology Preview from this location:

http://download.qt-project.org/development_releases/qt/winrt-tp/

When I try to build it using the instructions mentioned here , I eventually run into the following error:

        win_flex --noline --nounistd --outfile=Tokenizer.cpp ..\..\..\..\3rdparty\angle\src\compiler\preprocessor\Tokenizer.l
'win_flex' is not recognized as an internal or external command, operable program or batch file.
NMAKE : fatal error U1077: 'win_flex' : return code '0x1'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\BIN\nmake.exe"' : return code '0x2'

NMAKE : fatal error U1077: 'cd' : return code '0x2'

How do I fix this?

Answer 1

Try this: When you extract the sources, it will have a directory structure like this:

.....\\qtbase-opensource-src-5.3.0-WinRT-TP\\qtbase-opensource-src-5.3.0-WinRT-TP\\bin

.....\\qtbase-opensource-src-5.3.0-WinRT-TP\\qtbase-opensource-src-5.3.0-WinRT-TP\\src

The compilation script just looking for win_flex in a directory named gnuwin32. This directory and its content can be found at https://qt.gitorious.org/qt/qt5/source/4c925babf9e7f516479a0e418e9b3f509d3cd4b7:gnuwin32 or in the complete Qt5-Sources (WinRT Technology Preview Sources are just a subset). Copy this directory to the path, then it should look like this:

.....\\qtbase-opensource-src-5.3.0-WinRT-TP\\qtbase-opensource-src-5.3.0-WinRT-TP\\bin

.....\\qtbase-opensource-src-5.3.0-WinRT-TP\\qtbase-opensource-src-5.3.0-WinRT-TP\\src

.....\\qtbase-opensource-src-5.3.0-WinRT-TP\\gnuwin32\\

NOTE 1: Downloading win_flex from sourceforge or add it to the PATH variable does not work! Compilation script searching win_flex hard-coded in the gnuwin32 directory!

NOTE 2: I posted a comment on the official blog post, maybe the guys from Digia will fix the WinRT-TP-Source-Package soon...

Answer 2

I installed win_flex from http://sourceforge.net/projects/winflexbison/

Then in my source, I went to the directory: .....\\qtbase-opensource-src-5.3.0-WinRT-TP\\qtbase-opensource-src-5.3.0-WinRT-TP\\src\\angle\\src\\compiler\\preprocessor

and changed both Makefile.debug and Makefile.release to make sure that "win_flex" and "bison" commands are executed with their full paths specified from their install directories. This fixed the above mentioned problem.
