I have searched a lot on the web regarding how to setup allegro on wxdevc++(an extension of the old devc++)
I planned to switch to wxdevcpp from old devcpp, I downloaded and installed allegro 4.2.1 and also added the parameters and directories in the project options but it gives the error
allegro.h: no such file or directory.
Please help out , the whole night has passed searching about it.
For additional information i am here.
I am using windows8 32 bit.

I'm new to Qt, but have been working with Visual studio for C/C++ development for a few years. Now I'm trying to build a GUI for my project. I installed Qt 5.11.0 and the Qt VS Tools on both my work computer and home PC. At work I can build and run my project with the VS debugger, however on my home system I can build but can't run either with VS debugger or simply launching the app. I tried in release and it runs fine.
The error I'm getting is :
The code execution cannot proceed because VCRUNTIME140D_APP.dll was not found.
I get 4 of these, the first two want VCRUNTIME, the second two want MSVCP140D_APP.dll.
Solutions I've tried so far :
Uninstalled Win SDK and reinstalled
Uninstalled VS2017 and SDK and reinstalled
Searched System32, SysWOW64 and VS install directories - found msvcp140d.dll and vcruntime140d.dll, but no _app.dlls
Does anyone know what these are included with and where to get them? I can't figure out why I have them on my work computer but not at home. I have the same VS updates, same Qt version, and SDK on both systems.
Using :
Visual Studio 2017 v15.7.1
Qt 5.11.0 - msvc2017_64
I suppose I can just copy the .dll's from my work pc and drop them in the appropriate locations on the other, but I'd like to know what they should have been installed with so I can have the same setup on both systems.
Edit:
I also tried changing the platform toolset to VS2015 with Qt versions msvc2015_64 and winrt_x64_msvc2015
I found this post concerning the same missing _app.dll files. There wasn't any answer there, which is why I tried reinstalling the SDK in the hope the missing files were included there.
Edit 2:
I just scanned my entire system at work and it turns out that I don't have the missing .dll there either. That tells me that there is a difference in the project properties or configuration between the two. I use git for source control, and I am currently the only contributor to this project. When I try to build and run just the example from the getting started guide I have the same problem at home with missing _app.dll files, however it works fine at work. I'm totally confused now, and any hints are greatly appreciated.
Solution:
After trying for a couple of hours making new solutions etc. I decided to delete the entire build folder and put fresh copies of all the dependencies into it. My project now runs fine in debugging mode.
I'm fairly certain that when I originally copied the Qt .dll files into it I must have grabbed them from one of the winrt folders rather than the msvc2017_64 folder. To test I replaced the working .dll files with those from the winrt_x64_msvc2017 folder and sure enough the same errors again. So, this was a dumb mistake on my part, but hopefully it'll save someone else a lot of hair-pulling in the future.
I'm trying to work with OpenCL in Visual Studio and here's what's bothering me:
I have an ATI graphic card and so I downloaded AMD APP SDK, the latest version 3.1, and wanted to start developing on some example but got stuck because there was no "cl.h" nor CL folder for that matter in that SDK. I found that very strange, since in all the examples Ive seen the include was: #include . Then I downloaded an older version, I think its 2.7., and there was CL folder with cl.h file as well. I then also made sure all the library dependencies and include directories are set in the project properties and when i tried to run an existing OpenCL project there were no errors reported. However, when the program started it crashed because it was saying that "OpenCL.dll is missing". I looked in the SDK folder for the file and it wasnt there. I then downloaded opencl.dll from internet and copied it into debug folder and tried to start the program again but it crashed again with a message "Opencl.dll is either not designed to run on Windows or it contains an error.".
Im really lost here and would appreciate any kind of help!
Ideally you shouldn't download "Opencl.dll" explicitly, it should come as part of your drivers installation. Header files & Lib files can be part of SDK, but run-time files like "Opencl.dll" are not necessarily be part of SDK. Crash can be observed if there is no compatibility between the SDK files (Headers and libraries that you use for your application) and Run-time files (Opencl.dll).
So, make sure to update drivers corresponding to the SDK version that you use.
Also, the opencl.dll generally get placed in "C:\Windows\System32" & "C:\Windows\SysWOW64" when you install the drivers. Generally, this is the one that gets used during run-time
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 am trying to install Gnu Scientific Library (GSL) on Windows XP, but this is very difficult for me. I found this site
http://gnuwin32.sourceforge.net/packages/gsl.htm
from which I downloaded "Complete package, except sources" and installed. But this is only 6.2MB large, which I find to be very small. Is this correct? I would be happy to get some help with this.
I don't understand why this has to be so difficult.
I am beginner as well, but I just managed to have it work on windows 8 with codeblock 12.11.
installing gsl from the file you mention. Better to use a filepath without spaces (not sure if relevant here, just read this advices for installing other libraries)
in codeblocks, after creating your project:
right click on project name
click on build options
on the right part of the windows that opens, select the name of the project (root of the tree)
select the linker settings tab
click add
browse to the lib directory of your gsl installation and select libgsl.a
same for libgslcblas.a
select the search directories tab
click add and select the include directory of your gsl installation.
From this point things worked ok for me.
good luck.
My IDE of choice for the Mac (at least for C++ and Objective-C development) is Xcode. I have a 64-bit Intel Mac with OS X Lion installed, and Xcode version 4.2 downloaded from the Mac App Store.
My problem is that Qt is apparently not compatible with Xcode 4 (it crashes when launching projects generated by qmake), so I'm basically asking how I can integrate Qt with Xcode. I don't have to be able to run and debug the project from Xcode, just build it.
So I thought it might be a solution to use qmake as an external build system within Xcode, the problem is that I have no idea how to set up qmake as my build system, so that I can develop my Qt applications in Xcode 4.
Please help me! :)
Google shows up many pages, but this Qt4 with Xcode page appeared at first glance to be a fairly definitive resource. However, it was last changed in 2006.
Please check out: http://qt-project.org/doc/qt-5/macosx.html
There is a much more recent Qt Developer Network forum post that seems to have good info in it. Specifically, this reply from August 19, 2011 gives a complete recipe.
Update 25/05/2016:
The first two links are now dead, and not archived due to robots.txt.
However, I've updated the link to the forum post.
And here's a copy of emiguel's answer. It is now 5 years old, so I don't know how current it still is.
Hi,
To solve my problem I did the following.
First I`m going to have a subproject in Qt that mantains the graphical interface, I created this project as a C++ library, so I could include this in the main project.
The main project is a C++ project in Xcode (which is a plugin template with a lot of configurations).
Second, I ported the Qt project to Xcode using the spec macx-xcode parameter.
Third, having both projects in Xcode, I can attatch the library (in Qt) to the main project. To do this, right click in the xcode project and click in the "existing file..." option, select the xcodeproj file from the Qt project. Finally add the library to the linkage phase, this is done by dragging the lib file, wich is under the xcodeproj file, to the "Targets" section in the "Link binary with Libraries".
Fourth, import the Qt framewoks to the main project, to do that, right click in the main project, click in add a existing framework, select the Qt features used by the project (ex. QtSDK/lib/QtCore.framework)
And finally, add the header and library paths in the main project. Click in project menu->project settings, set the header search paths option with the Qt headers (ex QtSDK/include//) and the library search paths (ex QtSDK/lib//**).
That's all, now I can instantiate my own Qt widgets from the C++ project.
Note: I have to do an additional step because my target was i386 and the downloaded Qt version were 64 bit, so I downloaded the sources and compiled it for i386.
Now I have another problems about drawing inner the plugin... but I think that will be for another post.
Thanks a lot for your help
Finally, current information on building Qt in Xcode is available in Qt for OS X - which is too long to copy here, and will be maintained and updated by Qt...
