iOS XCode compile error: unable to execute command

问题:

I have a project which compiled perfectly in the past, but after the last xcode update (6.3.2) I get a compile error whenever I try to run it directly on a device. Building and Running it in the simulator works fine. The Archive function works fine as well. But no matter what device I connect or what iOS version the device is running, I always get the same compile error:

1. It shows me random files that I'm supposed to submit to the bug report.
2. I haven't made any code changes from a working version to the version causing the current problems and I even reverted to an earlier version which is live and running in the Appstore but still the same error.
3. I have deleted xcode and installed again trough the app store
4. I tried making changes to my code to maybe pinpoint any problems but since the source file of the problem changes every time, I don't really think anymore that it has anything to do with my code.

This is driving me mad. Any help is much appreciated

I tried to add the paypal framework to my iOS Project (Using Xcode 7.2 and Objective-C language), When building it is not giving any error, but when I try to archive the Project and trying to make the IPA, I am getting that Error

unable to execute command: Segmentation fault: 11

Screenshot:

After huge trying I have disabled the Bitcode in Project's Target->Build Settings->Enable Bitcode. Now the build can be achieved. Please check the following screenshot.

I found a fix for my problem:

I'm using a virtual machine and opened the project directly in the shared folder. I moved the project to the documents and now it works!

回答3:

We've just realized that segfault was caused by invalid unicode characters in our sources.

回答4:

I had the exact same problem. In my case I looked at the offending file and played around with it. I was able to resolve the error by commenting out a giant NSDictionary declaration:

 NSDictionary* glyphNameToUnicode = [[NSDictionary alloc] initWithObjectsAndKeys:
                                    @"A", @"A",
                                    @"\u00C6", @"AE",
                                    @"\u01FC", @"AEacute",
                                    @"\u01E2", @"AEmacron",

This thing had probably 300 lines maybe more. Instead I moved the declaration into a file and loaded the dictionary from the file. Not sure if that helps, but in my case those files were not random...

Its deff a bug with xcode though...

回答5:

Apparently it was a bug in my Xcode version. Had to revert to an old one and everything worked again. With the newest update everything was working ok again.

回答6:

Pods are provided xcode/.... path for installation from git and i installed xcode 7.3.1 and its named like xcode3 so i face this type of error but when i renamed it to xcode then this error is solved for me.

So In summary, First of all please check your xcode name in application section.

If it is not xcode then please rename it to xcode and try to run your app.

unable to execute command: Segmentation fault: 11.

I was able to turn off the bitcode and able to achieve the ipa. An in depth of what bitcode means can be seen here

回答8:

If you are using a virtual machine, then copy the files inside the virtual machine, don't import from your shared files, and it will work.

In order to solve a problem (a known bug closed as a duplicate as of this writing) that caused apps built under 10.12 (macOS Sierra) to fail to launch under 10.9 (even when they'd done so without trouble previously), I'd installed 10.11 and Xcode 7.3.1 under a VMWare instance. Xcode (due to laziness on my part) was copied to the Desktop.

After reading SmarterSusheel's answer regarding a renamed Xcode, it dawned on me it may be path-related, so I moved Xcode to /Applications and tried again. Problem (mostly) solved. I say "mostly" because I also had to copy my project folder into the VMWare instance since it seemed to have issues building under the shared folder as well.

回答10:

Setting Link-Time Optimization to NO in both Debug and Release mode is what resolved the problem for me.

回答11:

I was facing similar issue:

clang: error: unable to execute command: Segmentation fault: 11
clang: error: linker command failed due to signal (use -v to see invocation)

Simply updating from Xcode 7.2 to 7.3.1 has resolved the issue!

I only had problem for i386 architecture when building for iPhone 4s simulator running 9.3

When disabling bitcode didn't work (suggested above), i tried to look at the source code. I didn't find any ascii related stuff (suggested by others), so I tried to comment out method by method until I found the offending line. For me the error was caused by this:

let keyboardSize = ((info![UIKeyboardFrameBeginUserInfoKey] as AnyObject).cgRectValue.size)

Changed it into:

let keyboardSize = (info![UIKeyboardFrameBeginUserInfoKey] as! NSValue).cgRectValue.size
