When running my Delphi Project for the first time , it runs with no error. But the subsequent runs produces an error below:
[dcc32 Fatal Error] F2039 Could not create output file '.\Win32\Debug\Project1_p.exe'
I tried enabling my application Experience and setting it to automatic, as stated here with no luck. How to fix this permanently? Im using Delphi 10.1 Berlin.
UPDATE 1:
I know deleting the .exe, checking whether the executable is still running in the task manager and killing the process are the quick solutions. But I want a permanent fix.
You probably are running your application through the Run Without Debugging button (big green arrow Shift+Ctrl+F9), instead of that you should better run it through the Run button (small green arrow inside of a windows F9).
This way not only you can easily fix errors debugging your application line to line, but more importantly, when you stop the debugger (Stop button) the application closes and the executable is no longer in use, so you can recompile without showing that error again.
The quick fix that you are looking for does not exist. The compiler cannot write the output file if it is already being used as the executable for a running process.
The solution is to make sure that the process has terminated before you attempt to compile again. Quite plausible, it seems to me, is that there is a bug in your code that means that the process is not terminating when you attempt to close it.
Open your task manager and navigate to processes
Close all processes linked with your program, it usually says '.exe' at the end
lmk if it helped!

I have recently updated to macOS 13.0 and for that minimum XCode Version required is 14.x series. But my existing project never getting successfully building. Its getting stuck at some point.
Its not getting failed. Build process screenshot is attached below. Its not pointing to any specific class. Seems like there are lots of classes which are getting compiled successfully at last but still build process is stuck at some point:
Seen similar threads like below on apple pages but nothing seems working. Does anyone got resolution?

Something similar has happened to me in the past on a number of occasions. If the Swift compiler is hanging mid-build, usually the issue is that there is some expression that is too complex for Swift to do the type inference on.
What you need to do is first find the exact statement that is causing the hang. This is how I do it:
First find out which source file is causing the problem. Look at the build log to figure this out (the build log can be located by looking at the reports navigator ⌘9 ). Find the build log and click on it. The build log will appear in an editor window.
One of the compiles will still be in progress and its file is the one you want.
The next thing to do is comment out all the code and recompile. This time the compilation will finish (if you have the right file, or there is only one) but probably with a lot of errors. Then you add the code back in, function by function, until one of them causes the compilation to hang again. If it's not obvious which line of the function is causing the problem, comment it out again and then add the lines back one by one until the compilation breaks again.
Once you have located the line, you need to simplify the type inference on that line. If it's a closure, try adding an explicit declaration for its parameters and return type. If it involves some complex array, try adding a type annotation to its declaration. Also try breaking down complex expressions into multiple simpler expressions.
There's no one size fits all answer to this but usually, once you have located the exact line that is causing the problem, it should be reasonably obvious how to fix it.
I've got a weird problem when I try to Run/Compile in Delphi Berlin 10.1 Update 2 on Windows 10.
If I succeed to Run/Compile my project, and then quit the launched .exe, and try to Run/Compile a second time, without making any changes to my code, I get this error message:
[dcc64 Fatal error] F2039 Impossible to create output file '.\win64\debug\eedatelier.exe'
Sometimes it says eedatelier.rsm instead (most of the time).
I tried deleting all .dcu files, same result.
I made some changes in code and saved the .pas, sometimes it works, sometimes it doesn't.
If I erase the .rsm file, it works most of the time.
Sometimes I have to erase the .exe file to make it Run/Compile again.
I just don't understand what is going on.
I've searched around and can't find anything on this.
Using Swift 2 and Xcode Version 7.0.1 (7A1001). Every time I execute something in the debugger console, Xcode crashes.
The project is not very big, and has less than 10 third party frameworks.
I can't think of much more information that's relevant, but I'm sure there's more, so please do ask me if there's anything I should add to my question that would help.
I've of course cleaned build and derived data.
It's driving me insane. Thanks!
UPDATE 16/11/12
Submitted rdar://23559366.
How are you maintaining your third party frameworks? Via Carthage?
If so then this is probably your issue: https://github.com/Carthage/Carthage/issues/924
This is an issue if the location of the /Carthage/Build/iOS folder is in a different location to where it was produced (i.e if it was compiled on a different machine and the absolute file path has changed).
A temporary fix would be to run carthage build --no-use-binaries on your machine to rebuild the symbols using the current absolute file path working around the bug.
But if you wasn't using carthage then its probably not your issue so sorry
I had similar problem with Xcode whenever I hit breakpoint.
In case you see this screen right before your Xcode crashes - you are lucky and my fix might save you. All you need to do is open this window and in the Project Navigator, select any file that you want, so that instead of that white blank view you would get your code. After this you are most likely will be able to successfully stop your app at your breakpoint and perform the debug.
I am not sure why this happens, but I suspect that the reason is Debug View Hierarchy mode, which you might have triggered prior to setting you breakpoint and trying to stop at it. At least this is when it happens to me.
I have similar problem earlier.
If you try to print non-optional variable and unfortunately it holds nil value then it breaks/crash. so that make sure declare all possible variables as "Optional type".
I need to debug the startup for an ios application on an actual device... and by start up I mean the very first instruction that is is executed when the OS hands control over to the app. Not "main". Also, this application doesn't have any symbols (ie. the debug information isn't available.. yet). I don't care if I have to debug at the CPU instruction level. I know how to do that (done it for over 30 years). I want the debugger to stop when control is about to transfer to the app. When I use the Attach|by Name command and run, it just says "Finished running".
Oh, and this application was not built in XCode. It is, however an application I built, signed and provisioned and moved to the device. The application does run since I can see the console output. Just in case you're thinking I'm some hacker trying to debug someone's application.
How's that for a tall order? I'll bet nobody can answer this... I've not been able to find any information on how I could do this with an XCode-built project. I wonder if it is simply not possible or "allowed" by the Apple overlords?
What do you say, Stack Overflow gods?
UPDATE: I should clarify something. This application is not built with any commercially available or open-source tool. I work with a tools vendor creating compilers, frameworks, and IDEs. IOW, you cannot get this tool... yet. In the process of bootstrapping a new tool chain, one regularly must resort to some very low-level raw debugging. Especially if there are bugs in the code generated by the tools.
I'm going to answer my own question because I think I've stumbled upon a solution. If anyone has anything more elegant and simple than this, please answer as well. On to the steps:
Starting with a raw monolithic iOS executable (not a bundled .app, but the actual binary mach-o file that is the machine code).
Create a new like-named empty Xcode project. Build and run it on the device.
Locate the output bundle's .app folder.
Copy the above raw iOS executable over the existing one in the .app bundle's folder.
The application will now have an invalid signature and cannot be deployed and run.
Run codesign against the app bundle (you can find out the command-line by running xcodebuild on the above Xcode project).
In the bundle's .app folder, run otool -h -l on the binary image. Locate the LC_UNIXTHREAD load command and find the value associated with the 'pc' register. This is address where the os loader will jump to your application. If this address is odd, then these are Thumb instructions otherwise it will be ARM (I think that's how it works).
Add a symbolic breakpoint (I used GDB instead of LLDB) and enter the address as '*0x00001234' as the symbol.
Select Product|Perform Action|Run Without Building.
Assuming that GDB is able to evaluate the breakpoint expression and set the break point, and you've selected Product|Debug Workflow|Show Disassembly When Debugging, the process should break at the very first instruction to be executed in the application.
You can now single step the instructions and use the GDB console to get/set register values.
Your question does not make sense - main is the entry point into the application. It is the first code that should be encountered, unless possibly you have initialize() overridden for some classes (but even then I think main would get hit before the runtime).
I think you are seeing some kind of odd error on launch and you think you want to set a breakpoint on entry to catch it, but far more likely what would help you is to describe the problem on launch and let one of the 4000 people who have seen and fixed the same crash help you...
However, if you really want to use GDB to break on an application with no symbols (but that you launch from XCode) you can have GDB break on an assembly address as per:
How to break on assembly instruction at a given address in gdb?
To find the address of main (or other methods) you can use tool or atos, some examples in this question:
Matching up offsets in iOS crash dump to disassembled binary
ADDITION:
If for some reason XCode cannot launch your application for debugging, you could also jailbreak and install GDB on the device itself which would give complete control over debugging. If XCode can launch you application I see no reason why being able to break at an arbitrary memory address does not give you the ability you seek...
One solution for applications with webviews is to run them in the iOS Simulator, and connect to that with the remote-debugger in macOS Safari. This is off-topic but maybe the one or other could benefit.

Or use NetCat for iOS... not the most perfect solution, but at least you see what's going on.
I am creating an installer using the Adobe AIR captive runtime feature. Normally, the compiler generates a directory for me with all the necessary files that I then use to generate an .msi installer with.
Before, I could just double click the .exe file in this generated directory and the application would already work. (Good way of checking whether the generated files are valid).
I have now stumbled into the situation where I double-click the .exe file and nothing happens. No error message, no logs, nothing. The .exe file just exits immediately.
I have dug up and older installer of my app and tried to run this, the resulting install works fine. But once I replace my SWF file in the install directory with a new build of my app, I once again have the problem.
So, obviously SOMETHING in the Main.swf doesn't agree with the .exe file, but since there are no error messages or whatever it is extremely hard to figure out what the problem is.
The application runs fine from the IDE, by the way, the problem only occurs when I use it in combination with the captive runtime output.
Has anybody ever experienced something similar? And how were you able to figure out what was going on? Is there some secret place where AIR perhaps logs some errors, or is there a way to convince it to output some kind of error log?
You need to create a blank file with no extension called "Debug" (I used textedit and simply removed the extension manually). Put that in the META-INF/AIR/ folder, next to application.xml. This will cause the Air runtime to run in debug mode.
From what I can tell, if there are any fatal errors (e.g. a certain failover .swz file can't be loaded) then at least you'll be able to see what's going on.
Did you manage to make this work?
