LD: (null): Assertion failed: ("dylib not assigned ordinal"), function compressedOrdinalForAtom, file OutputFile.cpp,

After some editing my Xcode 5.1.0 source files I suddenly get this linker error:

0  0x1059b5f93  __assert_rtn + 144
1  0x105a1d7f5  ld::tool::OutputFile::compressedOrdinalForAtom(ld::Atom const*) + 281
2  0x105a1e469  ld::tool::OutputFile::addDyldInfo(ld::Internal&, ld::Internal::FinalSection*, ld::Atom const*, ld::Fixup*, ld::Fixup*, ld::Fixup*, ld::Atom const*, ld::Atom const*, unsigned long long, unsigned long long) + 2261

4  0x105a0f952  ld::tool::OutputFile::write(ld::Internal&) + 116
5  0x1059b6c40  main + 1012
A linker snapshot was created at:
    /tmp/keytech PLM-2014-03-05-101905.ld-snapshot
ld: Assertion failed: (0 && "dylib not assigned ordinal"), function compressedOrdinalForAtom, file /SourceCache/ld64/ld64-236.3/src/ld/OutputFile.cpp, line 3454.
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have absolute no idea what this means?

I already tried to:

Delete the derived data folder
Clean Files and build files
Cosed and reopen Xcode
Made sure no Linker Optimizer are active: No dead Code Stripping, No Link Time Optimization.

I also have excluded some of my latest changed code. With no result. Googleing the error did not find any useful information.

Does anybody have an idea?

Solution

In my case the linker error was gone after I switched in the Build Settings "OSX Deployment Target" from "10.7" to "10.8".
