The error message looks rather straightforward: qbs tried to run a 
compiler binary which does not exist. If you think that your Kit has 
valid compiler settings, you should file a bug report including more 
information, most importantly the exact settings of your toolchain as 
displayed in Tools->Options->Build&Run->Compilers.
[Wild guess: The problem could be that you are compiling C files and the 
toolchain points to a C++ compiler with an "unusual" name.]

I have Visual Studio 2015 installed but Qt Online Maintenance Tool does
not show me a version for that compiler. Do I have to build Qt myself?

[Qt-creator] Qt Creator 3.6.0. Unable to compile bare metal QBS

Hi Everyone,

I just updated to the new Qt Creator 3.6.0 to test out the new features.

I've been happily using the old Qt Creator with QBS to develop for ARM

[Qt-creator] Building master with MSVC12 and Qt 5.5 fails

2015-12-16 Thread Jochen Becher 
Hi,

I tried to build current master with MSVC12 and Qt 5.5. It failed
because Q_COMPILER_INITIALIZER_LISTS is not defined (needed to compile
some classes which use QVector<> constructor with initializer lists).

Is this a bug in Qt 5.5 (MSVC12 does support initializer lists due to
Microsoft's documentation) or should QtCreator not use initializer
lists yet?

Re: [Qt-creator] issue with syntax highlighting

Hi!


I've found some problem. There's no code highlighting under preprocessor
definition, even if definition is true.

Look screenshot 1
 before
and screenshot 2

after.


Looks like the editor document is not updated when the generic project 
defines change. Closing and re-opening the documents seems to help here.


Please create a bug report at https://bugreports.qt.io/ .


Definitions which are false are just grey
.

That's normal, your compiler probably behaves the same way.

Hi Dmitry,

first of all, please keep the mailing list included, your problem might 
be interesting for others too and you get more help the more people read 
from it.


That said, sorry, the custom parser for now only scans for errors,
not warnings. I already started to extend the parser but never finished 
it (time is short...):


https://codereview.qt-project.org/#/c/80533/

If you want to take over... feel free to do so. I'd be happy to review 
your changes.


Best regards,
Andre


Hi,

Yes, custom error parser works with _*"(.*)", line (\d+): (.*)$*_ , now
it showing errors in source code and I can make jumps to line in file,
but it treats all "errors" and "warnings" like an errors. Is it possible
to configure it somehow to treat them separately (errors are red,
warnings are yellow)? I couldn't find any documentation about error parser.

Regards,

Dmitry

It's quite possible, that your pattern is not recognized (correctly)

If you want to check yourself, its in gccparser.cpp, I could have a

A possible solution is to set up a custom compiler in
Tools -> Options -> Build & Run -> Compilers -> Add -> Custom and
then set up a custom error parser (regular expression based). This
one is a bit slower but should support every possible compiler :)

Qt Creator thinks that your file is called

main.c”

with a “ at the end.

What’s your compile output? (contents of “Compile Output” pane)

Hi Dmitry,

Looks strange, warnings are displayed as errors, and it seems Creator 
can't locate the file for the error. Please tell us more:


* Creator version
* Which compiler is this?
* How is the project organized?
  - Are the sources files in subdirectories?
(Best would be to send the project file)
  - Which is the working directory of the compiler?
* Please send the contents of compile output pane too.
  Are the errors marked red there?

Best regards,

[Qt-creator] stop button doesn't stop the process

2015-12-16 Thread cyb 
Hi,

I'm using an external tool for debugging, basically it's just a batch file
which is running some java script which is working with proprietary
debugger. Anyway when I'm running it in Windows 7 shell everything is fine,
it works and if you will close a terminal debug session (by closing a
window or ctrl+c) will be terminated normally, so script and stuff works
fine. But if you will try to run it in qt creator console and push *"stop"*
button to terminate debug session qt creator won't close session and it
will be still in processes so it will cause a debugger fault on the next
run. So why stop button doesn't stop a process? I still can debug it in
terminal window but in console would be better.

Thanks,

Re: [Qt-creator] Qml Designer does not always show QQuickItem

2015-12-16 Thread Hartmann Thomas 
Hi,

I changed the .metainfo file to just this:

import QtQuick.tooling 1.2

// This file describes the plugin-supplied types contained in the library.
// It is used for QML tooling purposes only.
//
// This file was auto-generated by:
// 'qmlplugindump.exe -v bug.qmlfun 1.0'

Module {
Component {
name: "QmlFun"
defaultProperty: "data"
prototype: "QQuickItem"
exports: ["CoreFun 1.0"]
exportMetaObjectRevisions: [0]
Property { name: "text"; type: "string" }
Signal {
name: "textChanged"
Parameter { name: "aText"; type: "string" }
}
Method {
name: "setText"
Parameter { name: "aText"; type: "string" }
}
Method { name: "update" }
}
}

The raise condition seems to be gone then and Fun always shows up in the 
navigator.
If you do not want to install the QML plugin to Qt you can define 
QML_IMPORT_PATH in the .pro file instead and deploy/build your plugin 
accordingly.
You can e.g. add QML_IMPORT_PATH = $$PWD/imports to the .pro file and 
build/deploy the plugin to imports/bug/qmlfun.

I have included the metainfo in the attachment and it look ok to me.

In order for everyone on the list to see what the problem is about without 
having to open the attacment (QmlFun.7z), I copied the README here:

Demo project for showing a bug in QmlDesigner/qml2puppet in Qt-Creator-3.5.1
based on Qt-5.5.1 and an unknown number of releases before. I have tested
the project on Ubuntu Wily Werewolf and Microsoft Windows 7 (32 bit) using
msvc2010.

Compile the project and install the plugin. This seems to mean, that you have
to install it in $QT_DIR/bin/qml/bug/qmlfun in most cases. Look at
"install.sh" for ideas.

One would think it should not matter where to install the plugin, however
most setups will fail on this (Qt on the development machine vs. copying
installation files to a client machine, running the downloaded Qt-Creator
vs a custom built Qt-Creator etc.). This is problem to talk about some
other time, though.

On Windows, the installed plugin should look like the following list:

bug/qmlfun/designer/fun.metainfo
bug/qmlfun/designer/images/fun.png
bug/qmlfun/designer/images/noFun.png
bug/qmlfun/Fun.qml
bug/qmlfun/FunRep.qml
bug/qmlfun/plugins.qmltypes
bug/qmlfun/QFun.qml
bug/qmlfun/qmldir
bug/qmlfun/QmlFun.dll

The generated plugins.qmltypes on Linux is different from the one generated
on Microsoft Windows. The Linux version references QtQuick, whereas the
Microsoft Windows version contains a copy of used parent classes. Exchanging
the versions does not alter the behaviour (works either way). I prefer the
Linux version, but I wonder, why the other version exists at all...

Restart Qt-Creator. Load TestQmlFun.qml and press "Design". Now you will
probably see what can be found in the screenshots/ folder. Continue quitting,
restarting Qt-Creator and loading the document, until all items are shown
correctly (may take 3-10 times or more). Now you start to consider, that
there might be a glitch in Qt-Creator or qml2puppet (I don't know,
I have not looked into the sources yet, it may aswell be something
completely different). You will almost always see all items in the state
view. If the central area shows all item, they will be visible in the
navigator as well and vice versa.

Qmlscene will always show all items correctly.

Thanks a lot for any insight or maybe even a fix,

I think this is a bug in the qmldumper.

Which leads to a raise condition in the code model.

This is a clear indication that the qml2puppet is working well. If things show 
up in the state editor then the puppet can obviously instantiate the item in 
your plugin.
But depending on the race condition in the code model the items are not derived 
from Qt Quick most of the time. Such items we do not show. You have to fix the 
.metainfo file.
I will have a look at the project and then can send you the correct .metainfo 
file.

Kind Regards,
Thomas Hartmann

Hi,

concerning the presentation problem of QmlDesigner in Qt-Creator, I have 
created an isolated project with just that problem in it, a few screen shots 
and instructions as an attachment. Please have a look and tell me I am seeing 
ghosts. I have tried this on a number of systems with the same result 
everywhere.
