Sorry, the current status is that lldb-server is no longer needed, however the debuggee process hangs and the lldb.exe is "froze" (i.e. it does not accept user input)
Here is the backtrace: http://pastebin.com/mbLFgCA6 I will try and get lldb built in debug mode for better debugging... but this will take sometime as the generated files are too large to written to the file system - (clang sources) I will teak the CMakeLists.txt files to fix this and will report back In the meantime, if you have any more hints/tips - I will be happy to try them here Thanks On Mon, Mar 28, 2016 at 10:13 PM, Eran Ifrah <eran.if...@gmail.com> wrote: > I was able to locate the problematic > code: ProcessWindowsLive::Initialize() was not called due to wrong macros > http://reviews.llvm.org/D18520 > > > On Mon, Mar 28, 2016 at 9:31 PM, Eran Ifrah <eran.if...@gmail.com> wrote: > >> Done. >> >> http://reviews.llvm.org/D18519 >> >> >> On Mon, Mar 28, 2016 at 9:28 PM, Zachary Turner <ztur...@google.com> >> wrote: >> >>> Almost, there's one more step.
