Whenever I try to run my app in Xcode 6 Beta 4 I am getting the error:
The file "MyApp.app" couldn't be opened because you don't have permission to view it.
This error appears no matter what simulator or device I target.
I have tried:
Deleting all Derived Data from Organizer in Xcode
Repairing permissions on my drive
Manually elevating the permissions of the built MyApp.app
Restarting my computer
Has anyone else run into this problem and found a solution?
I use Xcode6 GM. I encountered the same problem. What I did was to go to Build Settings -> Build Options. Then I changed the value of the "Compiler for C/C++/Objective-C" to Default Compiler.
Having the problem on DEVICE too (not just simulator)?
The other solutions only fixed it for me on simulator, not device.
For me this problem occurred (in Xcode 6) when I would try to change the main info.plist properties whilst trying to change my app name.
In info.plist I had changed Executable File name to something other than the default ${EXECUTABLE_NAME}...
I had mistaken this field for the field that changes the name of the app under the icon on the springboard.
In Xcode do the following
Window --> Organiser --> Projects --> The app with the issue --> delete button in Derived Data.
I then cleaned the project and voila
works
For me, a simple Product -> Clean worked great
I've fixed it by cleaning a build folder. Just went to 'Product' menu and Option+Click 'Clean'. After that a problem was resolved.
There was a problem with the Info.plist of the project. I created a new project with the same name in Xcode 6 beta 4 and then replaced the real project's Info.plist with the new one. The project then built and ran fine.
Look at the diff, it appears like the plist might have somehow gotten mixed up with a playground's plist. The bundle identifier was "com.apple.dt.playground.iOS-18300-13" and the executable and bundle names were "iOS" along with some other oddities.

I've had same this error in Xcode 8.2. The reason I found out for me, another Info.plist is added in my project while adding library (manually copy).
So that Xcode is getting confused for selecting correct Info.plist.
I just removed that Info.plist from the added library.
Then it is working fine without any permission alert.
Please check if you have changed Executable file => $(EXECUTABLE_NAME) to any other name. If you have changed this name then it shows this error. Please replace it with $(EXECUTABLE_NAME).
Product -> Clean (command shift K) fixed it for me
My goodness!! I spent hours to resolve this issue.
On XCode 7.3 I was having project with no issues.
Mistake I did
I just Added physical folders and moved my files into them, problem started.
I tried everything
Default compiler
Clean and build
Reset simulator and reboot simulator, Xcode, iPhone even mac
Updated Info.plist
Deleting Derived Data
Editing the permission on the folder of the project
Checking my architectures
nothing worked :(
How I resolved
I was about create new project and then I just deleted those physical
folders I added, clean build and YESS!!
It works!!
Try "cmd+shift+k" to clean the project and rebuild. At least it worked for me
Sometimes opening old project in new version Xcode will get this message.
Go to Issue navigator and follow the warning hint 'Upate to reconmmented settings'.
Boom, magic!
I had similar issue (xCode 6.2) for sample code downloaded. I tried to set Executable Name to Default in Info.plist but this didn't worked.
Instead change Compiler for C/C++/Objective-C to Default compiler (Apple LLVM 6.0) instead of Unsupported Compiler(com.apple.compilers.llvmgcc42) for project.
My Application was working fine on XCode 9.4, but when I opened my project in XCode 10 I was experiencing this issue. For me the issue was the build setting. I found the answer in this page https://forums.developer.apple.com/thread/112141.
In short go to File > Workspace Settings… > Build System and change it to "Legacy Build System"
1) Go Firstly Build Options.
2) Then changed the value of the "Compiler for C/C++/Objective-C" to Default Compiler.
clean and working :-)
I found that changing my compiler to LLVM 6.0 in the Build Options was enough for me (xcode 6.1)
I got same error on my Xcode 6.1.1 for a project downloaded from gitHub which was committed 4 years ago.
For me, setting Architectures to the default value Standard architectures(armv7,arm64) and Compiler for C/C++/Objective-C to Default Compiler in Building Settings worked.
I had the same issue in my project. Later on found that third-party (fmdb for SQLite) file used in project contained Info.plist.
Simply deleting the Info.plist file worked for me!
I recently meet the same problem for running an old project (initially created in Xcode 4.x) in Xcode 6.0.1.
I fixed the problem by changing the Architectures in Building Settings to the default value, which is "Standard architectures(armv7,arm64)".
Hope this could help anyone who got similar problems :)
I've had this error with a number of my older projects that I am getting out of the cupboard to update. It seems that using Xcode 6 with older code seems to bring this about for some reason.
I have fixed this in all projects that I have done this with by:
Delete Derived Data
in Product: do a clean
go to Build Settings in the project Target and go to Build Options and change the value of the "Compiler for C/C++/Objective-C" to 'Default
Compiler'.
I tried all of the listed answers and none of them was useful. The problem was due to existence of an another plist file linked from a submodule via cocoapods. Luckily this was my own module, so I just deleted this plist from the submodule project and reinstalled pods.
solution
Later on I understood that the key of the problem was in the name of that second plist: simply info.plist. You may rename the file and relink it via a sources section of a submodule
That second plist file had a unique name, so Xcode was not supposed to become frustrated. Even my target settings pointed on a main plist, not on a info.plist. Looks like Xcode takes special consideraions about that name
The bug reproduced in Xcode 6.4 and Xcode 7.0
Well in my case, I just rename the Bundle Name and Executable file values in info.plist same as project name. It worked for me.
What I did is here:
I deleted VALIDARCHS from Project
I deleted VALIDARCHS from Target
Build Active Architecture Only = YES (for Debug) Architectures
Standard Architectures $(ARCHS_STANDARD)
Also, File -> Project/Workspace Settings == New Build System
Xcode Version 12.0 (12A7209)
I had this similar problem. Somehow my value for the key Executable File got mixed up. Just change it back to ${EXECUTABLE_NAME} (Under your project > Info). Worked for me!
If you google the text of this error message you will find maybe 20 threads across StackOverflow, Apple dev forums, Reddit, etc. about Xcode failing to be able to run a compiled executable with this error message.
In these threads you will find many people offering various suggestions about how to fix the problem: changing product name to match project name, changing build phase options, something with info.plist, changing compilers to or from Clang, etc. Presumably the suggestions are offered in good faith because they solved the problem for someone, but the answers are so varied that it is clear that the error message is generic and this is an important point if you are receiving it: this error seems to mean that something is wrong with the binary. Ignore its actual text: it may have nothing to do with permissions.
There is no general solution to this error. The error message is totally generic; assume it means "bad binary file". The solution if you are receiving it depends on what you are trying to do, what has changed, why you are seeing this error all of a sudden. Google the specifics of your situation rather than this error message.
In my case, and I have a feeling this is a common case, what I was trying to do was build an old iOS project, nine years old I think, on modern Xcode. The solution was to switch to the legacy build system which led to a compilation error because in the old project there were not modern architecture targets, which could be fixed by manually adding them.
In my case main.m containing the main(...) function was not contained in the list of "Compile Sources" in "Build Phases". To check if this is the case, enter into Build Phases and look, if your main.m appears in the "Compile Sources" list.
Don't know if the problem is related but maybe it can be a solution for anyone pulling the hairs like me.
In my case, I have a project with a lot of targets. Each target is a customisation of that base project which is a Cocoa Touch Static Library and the targets, Applications. Even if the main file is added into the library compilation, but not in each target, that error message appears. So what I did? Manually added the main file to each target in the Compile Sources section and bingo, all fine.
For me the error was in the .plist file at the key CFBundleExecutable.
I had renamed the executable removing a space that was between two words. (Eg: from "Wild Racer" to "WildRacer"). Took 1 day to spot it!!
Xcode is soooo unhelpful in the debugging!
What solved it for me was setting Build Active Architecture Only from No to Yes.
with X-code 6.3.2
[Build Settings] Options.
[All]-[Build Options]-[Compiler for C/C++/Objective-C]-[Default compiler (Apple LLVM 6.1)]
Then rebuild the project, and it runs ok.
On http://developer.toradex.com/software-resources/arm-family/windows-ce/tegra/release-details?view=release-roadmap&issue=10304 it is stated that one should "Copy webservices.dll manually to the target folder \Flashdisk\System\" in order to fix a problem with Ethernet debugging. My problem is that I have no idea where I should copy the file from. Any ideas?
This is for WEC2013.
The file is located in your platform builder path if you build your own CE image:
C:\WINCE800\public\COMMON\oak\target\ARMV7\retail\webservices.dll
If you use a Toradex Prebuilt image, get in contact with the support team, they will probably send the driver to you: https://www.toradex.com/support/support.
I recently started working with WxWidgets (2.9.4) and was working through a tutorial I found, but it seems that I'm unable to load any images. I've already properly used the handler (for PNG) and the problem happens at run-time. Below is an image of the popup that is displayed when attempting to run the program.
Here is the code:
wxPNGHandler *handler = new wxPNGHandler;
wxImage::AddHandler(handler);
wxBitmap exit;
exit.LoadFile(wxT("exit.png"), wxBITMAP_TYPE_PNG);
wxToolBar *toolbar = CreateToolBar();
toolbar->AddTool(wxID_EXIT, exit, wxT("Exit"));
toolbar->Realize();
Connect(wxID_EXIT, wxEVT_COMMAND_TOOL_CLICKED, wxCommandEventHandler(mainWindow::exitProg));
Any help is appreciated.
EDIT: I forgot to mention that when I click Cancel, this happens:
I placed the exit.png file in the build directory (/Debug or /Release) as well as the source code directory, but it still has yet to see it.
What is your working directory?
If you are using visual studio and running using the interface ( F5 or ctrl-F5 or the little run button in the toolbar ) then your working directory is the folder containing the project file. So try copying your image file there.
Or open a command window, cd to one of your build directories, and run your app from the command line.
In general, to avoid this sort of problem, I alter the project properties so that the executable is NOT stored in one of the build folders, but in a new folder ( which I usually call 'bin' - my unix roots are showing! ) and also alter the debugging properties so that the working directory is the bin folder.
There are a couple of advantages to this technique:
Both the release and trhe debug version use the same folder, so you only need one copy of any extra file, like your image file.
It is easy to see the executable and extra files in the working directory without being distracted by all the .obj files that end up in the build folders
IMHO this is well worth the little extra trouble in maintaining non default project properties.
First of all, to avoid problems deep inside wxToolBar, always check the return code of LoadFile() or, alternatively, use wxBitmap::IsOk() to check that the bitmap was successfully loaded.
Second, while adding the handler explicitly as you did is perfectly fine, I'd recommend to just call wxInitAllImageHandlers() as it's simpler and has no real drawbacks unless you are looking to create the smallest program possible.
Finally, to address your real problem, the file clearly doesn't exist at the path you're loading it from. You can, of course, solve this by being careful not to change your working directly (or restore it after changing it) in your program and by placing the file in the correct place. But this is, as you discovered, error-prone, so a better idea is to always use full paths to your resources. To construct them, you will find wxStandardPaths useful, in particular its GetResourcesDir() method.
LLVM can create graphs in Graphviz's "dot" format, and automatically invoke a viewer to display them. By default it uses dotty to display those graphs. I know that I can change it to use a different viewer, but I was not able to find precise instructions on how to do so.
How can I make it open the graphs with a different viewer?
I'm running on Linux but would be interested in an answer for Windows as well.
I found out I'm supposed to change the CMakeCache.txt file in my build folder. For instance, to use XDot instead of dotty, I edited the LLVM_PATH_XDOT_P property in that file to point to the full path of my xdot.py file.
It now opens the alternative viewer successfully, after rebuilding the project.
I just needed to do this.
I managed to do this with a workaround: made a backup of dotty (just in case) and created a link from dotty to XDot.
cp /usr/bin/dotty /usr/bin/dotty_copy
ln -s /usr/bin/dotty /usr/bin/xdot
I believe you could also set some variable during configuration step (possibly LLVM_PATH_DOTTY), but I never tried this as I didn't want to recompile LLVM.
You may try hacking the DisplayGraph function or fidging with the makefiles until you manage to enable one of the #ifdefs in DisplayGraph.
