[lldb-dev] Makefile build

[Filipe Cabecinhas]

Hi all, 

I was fixing lldb's Makefile build system, and updating it with Dragos' LLVMLibsOptions and Charles' python packaging (with printf instead of echo -n) patches.

But I'm having some weird problems. Everything builds fine with FreeBSD (haven't tested the Python part yet), but on Mac OS X Lion (the latest), I get this:

The problem is that every symbol is there, but marked as local:
$ nm Debug+Asserts/lib/liblldb.dylib| grep __ZNK12lldb_private4Args22GetConstArgumentVectorEv
0000000000275230 t __ZNK12lldb_private4Args22GetConstArgumentVectorEv
$ nm Debug+Asserts/lib/liblldb.dylib| grep __ZN28GDBRemoteCommunicationServerC1Eb
00000000003beca0 t __ZN28GDBRemoteCommunicationServerC1Eb




Linking liblldb.dylib also had this error message, btw. I don't know how bad it is. There's not much info available:
ld: warning: cannot export hidden symbol __ZN4lldb7SBValue6get_spEv from /Users/filcab/dev/svn-llvm/build/Debug+Asserts/lib/liblldbInterpreter.a(ScriptInterpreterPython.o)



Any clues?
