Build Qt5 from git with msys2 fails on wrong includes

TinTin82

Hi,
i try to build Qt from source for windows desktop with mingw2. For that rison i do the following steps:

git clone git://code.qt.io/qt/qt5.git
perl init-repository --branch --no-update
sh ..\qt5.\configure -c++std c++11 -platform win32-g++ -prefix D:\0000_Tools\19_Qt\02_Prefix -opensource -debug-and-release -static -static-runtime -opengl desktop -nomake examples -nomake tests -confirm-license
make -j8

if i do that, i run in the following error:

D:/0000_Tools/19_Qt/01_GIT_Qt5/qt5/qtbase/src/corelib/tools/qcollator_p.h:57:10:
 fatal error: QVector: No such file or directory
 #include <QVector>

compilation terminated.
make[4]: *** [Makefile.Debug:15071: .obj/debug/qcollator.o] Error 1
make[4]: Leaving directory '/d/0000_Tools/19_Qt/01_GIT_Qt5/ShadowBuild/qtbase/sr
c/corelib'
.
.
.

if i look in the Folder:
D:\0000_Tools\19_Qt\01_GIT_Qt5\qt5\qtbase\src\corelib\tools
there is a file:
qvector.h
But not a QVector.h

If i Change the Linefrom
#include <QVector>
to :
#include "qvector.h"

this module compiles,
but the in run in a further include error:

D:/0000_Tools/19_Qt/01_GIT_Qt5/qt5/qtbase/src/corelib/mimetypes/qmimedatabase.cp
p:53:10: fatal error: QtCore/QSet: No such file or directory
 #include <QtCore/QSet>

and so on...

Can anyone show me what is going worng with that ??
May i bootstrap Qt with a Compiler which does not have a Qt installed by itselfe ??

Thanks in advance for the help,
TinTin

Hi,

Why not build Qt with the version of MinGW provided directly with the installer ?

TinTin82

Hi SGaist,

I really wanted to avoid that to pervent too much compilers on mu System ...

SGaist

What version of MinGW do you have installed ?

TinTin82

gcc —Version 7.3.0 ( msys2 muild in )

SGaist

So you have an error in your title. You wrote Build Qt5 from git with mingw2 fails on wrong includes

Did you already saw https://wiki.qt.io/MSYS2 ?

Thx, i have changed the title "mingw2 -> msys2"

Hi,
I had the same problem and found this thread by googling.

After asking on IRC Thiago told use the solution : you have to put another perl distribution in your PATH before msys perl (Thiago recommended StrawberryPerl, I also tested with ActivePerl and it seems to work) and then run ./configure.
