Crash when trying to inject #11

Open seboslaw opened 11 years ago

seboslaw commented 11 years ago

Hey,

when trying to inject code while running (in XCode 5.0.1) I'm getting an EXC_BAD_ACESS exception within dyldbootstrap::start(..):

Bundle "InjectionBundle2.bundle" loaded successfully.
dyld: lazy symbol binding failed: Symbol not found: _llvm_gcov_init
  Referenced from: /Users/svogelsang/Development/work/testproj/iOS/iOSInjectionProject/build/Debug-iphonesimulator/InjectionBundle2.bundle/InjectionBundle

  Referenced from: /Users/svogelsang/Development/work/testproj/iOS/iOSInjectionProject/build/Debug-iphonesimulator/InjectionBundle2.bundle/InjectionBundle

The console shows:

Err.. never come across that before. Do you have a small test project that demonstrates the problem you can send through? Email is in the plugin menu.

seboslaw commented 11 years ago

phew....problem is that this is a rather large and complex project. I guess that is also the problem here. I'll try to setup a test project and add all my dependencies one by one and then send you the thing once it starts crashing again.

johnno1962 commented 11 years ago

sorry, otherwise I don’t have a lot to go on.. It seems to be something to do with testing: http://stackoverflow.com/questions/566472/where-are-the-gcov-symbols, try editing the bundle project and adding some of the flags they mention. Let me know how you get on.

johnno1962 commented 10 years ago

Hi, I’m closing this now unless you’ve found what the problem is.

kunalbalani commented 10 years ago

I have this same problem.

MaciejGad commented 9 years ago

I think that problem is caused by CLang Code Coverage. As mention in http://stackoverflow.com/questions/19290946/clang-code-coverage-mac-os-x-linker-error the best answer is to add following Linker Flags in InjectionBundle.xcodeproj:

-Wall -fprofile-arcs -ftest-coverage
johnno1962 commented 9 years ago

Thanks Maciej. Sebastian. is there any chance you can verify this works and I’ll push it onto github.

seboslaw commented 9 years ago

@johnno1962 I'm sorry. I cannot even reproduce my old issue with Xcode 6.1.1. Everything works fine now.

johnno1962 commented 9 years ago

Thanks for letting me know. I’ll leave things as they are for now and leave this open for reference.

fschaper commented 9 years ago

Had the same problem. @MaciejGad suggestion worked for me as well. -Wall -fprofile-arcs -ftest-coverage

luoqisheng commented 8 years ago

Had the same problem,-Wall -fprofile-arcs -ftest-coverage worked for me. but after the bundle was loaded,all my viewcontrollers was gone.
