I am trying to build QtCore.lib and I get this weird error.
PRJ0019: A tool returned an error code from "MOC kernel\qtimer.cpp"
I am able to build qtmain.lib but not able tp go any further.
moc.exe is available in bin folder and the path is added to my PATH.
kernel\qtimer.cpp file is also present in corelib folder.
Any help in this regard will be appreciated. I am building with Qt-4.5.2 source.
In Qt 4.5.2 moc.exe has some issues. An email I sent to Qt Support mentions it moc'ing files that were not modified. It could have further issues, which could be related to what you are experiencing.
Sorry I can't recall the exact details. To make things worse the link Qt Support had sent me at the time is broken.
They had suggested using 4.5.3. I think we ended up staying on 4.5.1, which we are still using today, although the move to 4.7.x. is occurring as I write this. :)

I have newly installed Qt and when I tried to open my projects and have not even tried to compile, I got this mysterious cannot find feature windows_vulkan.
My QT has been working earlier but I had to reinstall it because it complained I had missing libicuun65.dll and libicuuc65.dll and recommended reinstallation. I have removed everything and installed qt from scratch.
Below is my error
I went into the directory it specified and clearly see the file. I am just not sure the content of the file is complete as it only contains 2 lines below:
load(windows_vulkan_sdk)
QMAKE_LIBS_VULKAN =
Maybe there are lib that are missing like libicuun65.dll and libicuuc65.dll and/or others?
Also, please note the uncompleted "Prepare C++ code Model" status bar. It has never completed as I saw it there for hours...it should not take that long.
What should I do to rectify this issue? Please help.
Update: My paths are set up too...
I think I understand why this happens for you, you install your Qt in Drive D but install Vulkan SDK in Drive C.
These should be on the same Drive.
Maybe Qt can't find your Vulkan SDK because of that please reinstall Vulkan SDK in Drive D.
another thing is this link in bugreports.qt.io
and also this GitHub issue.
They have problems like you and their compiler was MSYS2.
In
\msys64\mingw32\qt5-static\share\qt5\mkspecs\common\windows-vulkan.conf
changed:
From: load(windows_vulkan_sdk)
To: load(win32/windows_vulkan_sdk)
This has been killing me for the last couple of days. I have read everything I can find on this error and have done what xamarin says but it still doesn't work.
I can't get my builds to get through azure pipeline xamarin.ios build and deploy to apple.
When I build locally I get messages like
MTOUCH : warning MT1502: One or more reference(s) to type 'UIKit.UIWebView' already exists inside 'Xamarin.Forms.Platform.iOS, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' before linking
with a companion message that says no references after linking
when I use --warn-on-type-ref=UIKit.UIWebView with the optimize arg.
When I build on azure in my pipeline, I only see the MT1502 but nothing saying anything after linking. The build gets submitted to Apple and fails because of the ITMS message.
I don't know what to do. I am using the latest macOS vm image, mono 6.8.0.123, xamarin.ios 13.16.0.13, xcode 11.4.1. The pipeline worked fine before April 30 deadline, now no matter what, I can't get the linker to strip UIWebView.
Let me know what other info would be helpful. I am completely stuck at this point.
Thanks.
I just got my build to pass Apple's inspection.
What ended up working for me was building locally and packaging the ipa file. On my mac I then changed the ipa extension to zip and unzipped it. I used terminal to go to the YOURAPPNAME.app "folder" and used grep -r UIWebView . to search for references. Don't forget the . so it searches the current directory. I missed that at first and got some message that grep was listening on stdin.
For me that resulted in a line like this:
Binary file ./Frameworks/PersonalizedAdConsent.framework/PersonalizedAdConsent matches
Now, the important thing to note is the linker never warned about this, so I was completely unaware of it. In my case it was part of Firebase/Admob. I was only one release behind and updating to the latest fixed my problem.
I still am using --optimize=force-rejected-types-removal --warn-on-type-ref=UIKit.UIWebView -warnaserror:1503 as my mtouch args. But builds now get through.
I hope this helps point you guys in the right direction, I've spent the last 3 days just trying to get builds to upload reading every post I could find on the web on this problem.
Solved !! I had to update the way how nugets are included to the iOS project .csproj file. The problem was that linker despite the --optimize=force-rejected-types-removal flag was not removing the UIWebView component form Xamarin.Forms 4.6 probably because it did not see it.
My project was created over two years ago and I was still using the packages.config file. After the update the flag started to work and grep query returned 0 :). The best way is to compare the old .csproj file with freshly created iOS project .csproj file and see how VS is referencing nugets.
I have downloaded the Xamarin.Forms solution from GitHub and I am trying to build the solution. Visual Studio does not build, generating more than 70 errors, as simple as the one below:
"The type or namespace name 'IOnClickListener' could not be found (are
you missing a using directive or an assembly reference?"in
Xamarin.Forms.Platform.Android\AppCompat\ButtonRenderer.cs
When I investigate the code, I see that there is really no reference to Android.Views.View in the using statements, so it seems fair.
Am I making a mistake somewhere?
It's not easy to get to the answer without digging into the logs but here are some steps that have helped me in the past.
Android Specific Steps:
Check the logs for any problems that stand out, look at the top most error first and work your way down. Output window -> Show output from Xamarin Diagnostic
If you find unzipping problems you might have to visit the Xamarin folders to delete the zip causing problems and Xamarin will download a new one.
C:\Users{USER}\AppData\Local\Xamarin
If you get loads of Xaml and Resource errors you might have to delete the contents of the file.
Resources\Resource.Designer.cs
After deleting the content(not the file), clean the solution, rebuild the project.
If you still have problems try to either downgrade Xamarin.Forms or upgrade it.
Change Api level to a higher one on the project properties.
Hope one of these helps.
I'm trying to add ParseKit to a new command line project in Xcode, but the framework shows as red in the Project Navigator. When I try to build, I get this error
error: /Users/acdlite/Xcode/Chemistry Parser/../parsekit-trunk/build/Debug/ParseKit.framework: No such file or directory
I've followed the directions given by the developer in this answer: How to embed ParseKit as a private framework in a Mac App bundle.
To my knowledge, red indicates that the file is not at the specified location. The file inspector says it should be located at /parsekit-trunk/build/Debug/ParseKit.framework, which actually doesn't exist if I try to navigate there in the Finder. So then where is it located? I have no idea.
I've followed all the steps from scratch like a dozen times now, including checking out the code via SVN. It's driving me crazy, and I feel like an idiot. I wish I could be more specific but I am truly lost as to where to go from here.
Alright, after at least 20 attempts I eventually got it working. Mostly, I followed the steps given by the developer in this answer: How to embed ParseKit as a private framework in a Mac App bundle
However, following the steps exactly didn't work. For the life of me, I couldn't get the ParseKit framework to show up as an option when I attempted to add it as a dependency of my Target. Xcode would just say "No filter results found." So I skipped that step. I also did not add a "Copy Files" build phase. Doing so resulted in a dependency error.
This was way harder than it should have been, and I don't know if that's because I'm stupid or Xcode is poorly designed. Probably a combination of both.
By the way, I'm using Xcode version 4.6.1 (4H512).
I am trying to compile a Qt Library Project to use its DLL as a plugin of my Main Application.
I've come across this particular error and I cannot seem to get past it, no matter what I try.
I believe cluttering the question with code tags is pointless when I can just provide you with the "working issue" (for lack of better wording).
This is a link to both projects. The main application AND the plugin I am currently testing on.
(please remember to modify the path in the Application project of the dll. I am using absolute path, which will most likely never be the same one you will use. I used absolute paths to make sure the problem was unrelated to finding the file itself)
So far I've checked:
My Qt version is, indeed, 4.8.2. Built with VS2010 Command Prompt.
As far as I understood the documentation, my code (particularly the APlugin project) follows the documentation instructions word by word. There's some space for human error, but I believe I got it right. as specified here(The Lower-Level API: Extending Qt Applications)
I am able to generate other QPluginLoader::errorString() errors (for example, using an invalid path to the .dll file will return a "file not found" error). Thus diminishing the margin of error in its use.
As of today, Google results are, at best, cryptic and/or do not apply to my current context of development (I am on VS2010, Win7 N Ultimate, Qt 4.8.2)
I believe it's better that I provided projects where the issue is reproducible, instead of just cluttering the question with code, but if you think I still should copy-paste my code, let me know and I will provide it explicitely in the question.
The only thing I am able to provide so far is that, albet I don't use a .pro file, I shouldn't need it, because my application will be windows exclusive, and the vcproj file already contains that data.
