[LLVMdev] Enabling debug in LLVM-1.7 release

[Silken Tiger]

Hi

This may sound like a stupid question, but well i am not very good with the automake tools:
How do i enable debug mode in llvm-1.7?

I tried 
./configure --enable-debug-runtime
editing Makefile.config  DEBUG_RUNTIME=1
editing Makefile.config.in DEBUG_RUNTIME=1 and ./configure --enable-debug-runtime

Currently i managed to make a profile build but gdb just chokes like this when trying to debug:
Starting program: /work0/tstone/llvm-1.7/Profile/bin/llc /work0/tstone/llvm/Profile/bin/llc
[Thread debugging using libthread_db enabled]
Error while reading shared library symbols:
Cannot find new threads: generic error


Thanks
