I am trying to install LibQxT to use it with Qt5, so I downloaded the sources and as soon as I run the configure.bat there is an error:
LibQxt requires 4.3 or newer but Qt 5.2.1 was detected.
Searching on the web Ive found out that apparently it doesnt know the correct path to the qconfig.pri (as seen here (last post)) so it doesnt really detect the version.
I have tried adding the path to the variable QTDIR in the ways described in the post (I tried to do it in the qmake cache located in the Libqxt folder and tried to define it as a environment variable). I havent found any clear solution to this problem, so I hope someone knows by now how to solve this issue.
Thankyou.
EDIT
What #vahancho said its true, if its not detecting the version, why does it name it? Perhaps its not detecting it properly.
But if it is, why cant it see that my version is higher than the requested one?
I have located the error and it fails at some point betweeen the echos and the if:
echo Configuration successful.
echo Generating makefiles...
cd %QXT_BUILD_TREE%
%QMAKE_BIN% %MSVCMODE% -recursive %QXT_SOURCE_TREE%\libqxt.pro
if errorlevel 1 goto mainqmakeERR
You can try to use the latest development branch of libqxt which could be found here. It will be compiled with Qt 5. You can just clone one copy of the source code by:
git clone https://bitbucket.org/libqxt/libqxt.git

I am trying to compile QDoc following the steps given here https://wiki.qt.io/Building_Qt_Documentation. I am trying to compile QDoc without building the whole Qt project. I use mingw in windows 10. I run first configure in the main qt directory, then configure in qtbase, then make in qtbase. I am going then in the qtdeclarative directory and try to compile sub-qmldevtools as explained in the tutorial. Unfortunately the target is not recognized and no compiling occurs. Can anyone help ?
I have finally installed the QtDocs. For Qt 5.8 it worked almost as here: https://wiki.qt.io/Building_Qt_Documentation except for make qmake_all should be called immediately after configure is called in the root directory of the sources. Also i had to compile qtattributionsscanner from qttools for the make html_docs to work.
Alternatively to compiling the documentation one could also use zealdocs, that is one offline help tool for varios software APIs.
I have OSX Yosemite 10.10.5, QtCreator 4.1.0, Qt 5.7.0 and Xcode 7.2.1.
If I write any native C++ program in QtCreator (console, gui - anything) I am unable to debug that program from QtCreator. Breakpoints get ignored, the program executes without pause and runs to completion no matter what I try.
I have tried the Xcode's LLDb, system GDB and Homebrew GDB as debuggers. the versions of GDB fail to start. Homebrew GDB has been codesigned.
This all used to (a few year back) just work beautifully and I am at a loss as to what might have changed.
Curiously, if I generate an exception inside the program - like accessing through a null pointer, the debugger shows me where this happens in just the way I would expect so, presumably, the debugger is running but simply treating me with complete disdain.
I know there are many versions of this question but none seem to address the problem adequately or offer workable solutions, or they apply to much older versions of the products.
Any suggestions?
This version of qtCreator (4.1.0) saw the return of the warning about having the build directory at the same level as the project directory. In Windows, this is done automatically. My mac installation does not get it right. (I may have messed a while back - cannot remember).
So - if the build directory is inside the project directory, debugging fails. Move the build directory up to the same level as the project directory and everything seems to work fine.
You can set the default build directory in the preferences/Build & Run dialogue. The path should start with ../
You will need to think about the folder structure before setting up the project unless you want build folders appearing in awkward places. So, a project folder structure like this is OK:
But one like this is not:
If this was already obvious to you, great. I have been messing with this for ages.
Many thanks to those who replied and anyone else who took the time to read the question. What helped e find it was the suggestion by #AlexanderVX that his setup was the same as mine but his worked. The only bit of my setup he could not see in the screenshots was the start of the build path. So that was the clue.
im planning to build a c++ application based on another c++ package (aria2c) i found over the internet which acts as a ready made wheel for me. I have already installed the package on my machine, but the problem is when i run system("aria2c"); it outputs "command not found", whereas if i run system("git"); (which i have also installed) it will output the git's man page.
calling "brew" also doesnt work whereas git, ls and some other that i tried work.
So can someone explain to me why i cant access that package ? and if there is any solution to it ?
The most common mistake is that the pacakge might be installed for a particular user or at a particular path. Make sure that you have the library/application in your path list
To do that ,i would suggest first finding where the package is installed and then do echo $PATH in terminal to see if its in your path variable
i spent a lot of time trying to get these to install properly, so here i am.
I've already googled my problem countless times in different forms and still can't resolve it.
It's just very confusing because there are so many versions out there, and i don't even know how to build the binaries, if even have to do that, and i couldn't find the configure.exe. I don't have it after i installed QT5.
I have python, perl, Visual Studio, QT5,QT addin, and openssl installed.
When going to QT5, QT Options, then Add, add: C:\Qt\5.2.1\mingw48_32 as the path and got an error about qmake not found or something.
So I deleted libqtmain.a and libqtmaind.a as suggested by some site and that solved the problem.
I've also tried this: http://blog.kikicode.com/2011/09/qt-version-uses-unsupported-makefile.html
but i couldn't find the Trolltech folder, so i stopped.
But now my problem is this
"This QT version uses an unsupported makefile generator (used: MINGW, supported: MSVN.NET, MSBUILD).
I don't even have a configure.exe file, and can't launch it from the visual studio command line.
I really have no idea what to do. I've been attacking this problem for all of yesterday, and i've ran out of steps today. Please help me.
I don't have the express version of VS. Just so you know.
I just solved this issue. It get me mad, but is easy.
The Add-in looks to $(QTDIR)\mkspecs\default to know which one to use. The "default" folder is not created after configure and build Qt.
So the way I solved is to copy&paste the "win32-msvc2013" folder as "default".
And now the Add-in recognised Qt.
BTW, after build the sources "nmake", I make an install of them in another folder so I have just the binaries and tools but not all the source that I don't need for develop software based on Qt.
Once the compilation is complete, then type:
Set the root where the installation will be, ex:
set INSTALL_ROOT=\Sw\Qt\qt-4.8.5-install
Execute in your source's root the command:
nmake install
So after trying everything i decided to run compile the binaries.
I think not a lot of people have this problem and there is no solution on the internet because the 2013 addin is very new. So here is what i did, and what worked for me, after countless hours of trying.
I downloaded the zip located under the main downloads on their webpage: http://qt-project.org/downloads
I uninstalled the old QT. (kept the addin)
I unzipped the zip it into a folder i named QT at C:\
Then i ran the configure.bat located inside.
On the Visual Studio cmd i cd to the C:\QT\qt-everywhere-opensource-src-5.2.1
directory where the configure file is,
Tried running the 'configure' file, there was no configure.exe. Then i ran 'nmake', that took like three hours.
The i went into C:\QT\qt-everywhere-opensource-src-5.2.1\qtbase\qmake
and made a folder bin where i copied the qmake.exe found in that same folder.
Finally i went into the VS addin, qt, qt options and i added that directory.
And it works!
I'm using Qt 5.6, msvc2014, but had the same issue at first. This issue was solved for me by updating to Add-in 1.2.5 without changing anything else.
I'm trying to use Qt4 using the Code::Blocks IDE. I'm running Linux Mint and I'm getting some errors. I looked around and found some people that had the same problem as me, but I can't seem to get their solutions working on my computer.
I installed Qt4 using the command
sudo apt-get install qt4-dev-tools
And when I type whereis qt4, I get qt4: /usr/lib/qt4 /usr/include/qt4 /usr/share/qt4
If I select "Create new Projet" in Code::Blocks and Select Qt4 project, it asks for Qt's location, which is $(#qt4) by default. If I click next, it says Code::Blocks doesn't know the "qt4" variable and gives me a prompt to set the base location, the include directory, etc.
Since I don't have any idea as to what I should be putting in there since nothing works (either it says "QTCore cannot be found in the specified directory", or the "lib" directory couldn't be found, etc.).
I tried what was posted on this forum: http://crunchbang.org/forums/viewtopic.php?id=18210, but it didn't solve my problem and I get the same errors.
In the "/usr/share/qt4" directory, there's a link to the "include" directory, but not to the "lib" directory.
I'm pretty new to Linux and all of this, so I'd like it if the answer was very detailed explaining what I did wrong / what I have to do.
Install the QtSDK
As a first step I would advise you to download directly the QtSDK, from the project site here.
Note: You could also use the precompiled version for your Mint version,
but in my personal experience, when working with external SDK,
you have more independence in development, it also allows you to work
freely with multiple versions of Qt simultaneously without move any
dependence of your OS.
You can follow the graphics steps to install the SDK, I advise you to check the option "download source", later this is going to be used for debugging code, and if necessary will allow the recompilation of some classes.
Now your QtSDK is installed on the folder eg "/usr/local"
So, all references inside your IDE should refer to this location.
Install the C::B
You can use the version available in "Software Manager"
Configure the C::B
When we start a new project and asks the location of our SDK we indicate this directory /usr/local/QtSDK/Desktop/Qt/4.8.1/gcc
Now the project is ready!
Note: "/usr/local" and "4.8.1" are variables depending on where
and what version you have installed.
Is very likely that your build directory, is not correctly assigned in "Settings->Compiler and Debugger->Toolchain ...->Compiler's Directory"
will be the default "usr" which should be replaced by "/usr/bin"
Now, when compiling with the standard project ".pro" and if your project has the requirement to use a "moc" tool strategy, the simplest way to do that, is use a customized Makefile, with all stages of compilation.
To learn how to make a customized makefile, you can read this answer.
And although I would advise again:
Although that CB is an optimal environment for working with wxWidgets, and C/C++ in general, I personally think that in the case of working with Qt, QtCreator provides a development environment more native and optimized to work with your projects QT.
