No Debug information of an iPhone app
- by Markus Pilman
Hi all,
I wrote an iPhone app which uses a third party library. I crosscompiled this library successfully and everything works smoothly. But when I want to debug the application, it would make sense to also be able to debug the library.
So I compiled also the external library with debuging information (usign the gcc option -ggdb). But when I want to debug it, I get the correct symbol names, but the positions are always wrong/extremly wierd (locale_facets.tcc:2505 or iostream:76). For example a stack trace could look like this:
#0 0x000045e8 in zorba::serialization::SerializeBaseClass::SerializeBaseClass () at iostream:76
#1 0x0001d990 in zorba::RCObject::RCObject () at iostream:76

Does anybody have an idea, where these wrong locations come from?
