The Xcode project will check out the sources for you into: lldb/llvm
If they aren't already there. Then it will create lldb/lldb-build and configure/build into that directory in a way that works for multiple architectures. So making a build folder inside llvm might work for you, but it won't be used by Xcode. If you want to do manual builds you can cd into: lldb/llvm-build/Release+Asserts/x86_64 Then run make from there. > On Aug 22, 2014, at 11:11 AM, Zachary Turner <ztur...@google.com> wrote: > > I will try that.
