Hi,

Which exact version of Qt are you using exactly ?

ham13

@SGaist QT6.

QT6

This is not the exact version. Also you did not answer which compiler you are using.

@ham13 said in type_traitsFile not found:

I've tried setting v5 and v6 and all sorts of kits and compilers

Which compilers?

The default GCC version in LM 21.x is GCC 11.2.
I think the default GCC version in LM 20.x is GCC 9.4.
Are you using an older Linux Mint?

ham13

I'm using Mint 21.2 Cinnamon which I belive is the latest version.

Using version QT 6.6.1 (gcc_64).

C Compiler - gcc(C, x86, 64 bit in /usr/bin)
C++ Compiler - CLANG 11(C++ , x86 64 bit in /usr/bin)

Build settings indicate correct directory for QT6.6.1 and the compiler is CLANG(C++, x86 64 bit in /usr/bin)

QMAKE /home/XXX/qt/6.6.1/gcc_64/bin/qmake

QtGrreator 6.0.2 built on 5.15.3

I believe all gcc compilers above v8 support c-17.
No matter which compiler I use it produces the same error. If I'm using the wrong compiler tell me which to use. The highest I have is V15. Hope the info above helps.

If there is a way to upload the project, I'm willing to do that and let you guys try to build it.

Thanks,
Marty

Forgot to mention I'm using QtCreator to build the project from it's .pro file.

That is C++17. I appears you are not using the GCC C++ compiler.
From the CLang LLVM docs:

By default, Clang 16 or later builds C++ code according to the C++17 standard. You can use Clang in C++17 mode with the -std=c++17 option (use -std=c++1z in Clang 4 and earlier).

So, when you build your project, exactly how is the compiler invoked?

Do you have the GCC C++ to try? What version is that GCC compiler?

/usr/bin/g++ --version

Does the referenced file even exist on your machine?

I'm using qtgreato,r with the compilers noted in my last post, to build the project from it's .pro file.

the .pro file
TEMPLATE = subdirs

!contains(CONFIG, no_zint){
CONFIG += zint
}

include(common.pri)
contains(CONFIG, zint){
SUBDIRS += 3rdparty
}

export($$CONFIG)

CONFIG += ordered
SUBDIRS +=
limereport
demo_r1
demo_r2
console
designer

!contains(CONFIG, embedded_designer){
!contains(CONFIG, static_build){
SUBDIRS += designer_plugin
}
}

and the .pri file

CONFIG += zint
include(./limereport/limereport.pri)
contains(CONFIG, zint){
include(./qzint.pri)
}

Zint is a 3rd party barcode generator that must be built before Lime Report. Lime Report can be downloaded fro Sourceforge. It is a report generator.

If there is another way to build this project without using qtcreator?

Both files are at the end of the list in the last post.

Your last post says you are using CLang 11 for C++ and your choice of Qt qmake says you are using GCC.

@ChrisW67 said in type_traitsFile not found:

So, when you build your project, exactly how is the compiler invoked?

Still unanswered but the next step will make this obvious.

@ham13 said in type_traitsFile not found:

Sure.

mkdir /tmp/build_dir
cd /tmp/build_dir
/home/XXX/qt/6.6.1/gcc_64/bin/qmake  /path/to/source/project.pro
make

(Exactly the same sort of steps that Qt Creator takes on your behalf).

Used the code from the last post to build the Zint 3rd9arty part of QtRptProject. Build success. Tried the same code with the main project QtRptProject. Got errors. The last lines from the make file:

Where to now?

@ham13 Will try agian today. Asked the programs author about the errors. He replied "it builds for me on both qt5 and qt6". When I asked how he built it on qt6 got nothing but silence. Hope you all can help get this thing to build. I'll post what happens today when I try again.

Thanks,
Marty

@ham13 I have the same result with Qt 6.6.1/GCC 11 on Ubuntu 22.04. I cannot yet see the connection between the line identified in the error and the type of error (std::pair-related type conversion issues)..

I do note, however, that some of the components are venerable and do things that cause problems. For example, QXlsx forces C++11 flags on the compiler, generating warnings about C++17 requirements (and probably plenty more). Zint appears to be of Qt4 vintage. Qt6 is supported though the QT5 compatibility layer.
