ProDBG is a new debugger under development that will support a variety of targets and operating systems. Currently it's in very early development and primary focusing on Mac as primary target. This is how it currently looks.
Mac build status
Windows Win64 build status
Linux build status
Major redesign of the ProDBG is currently happening so be aware that not much is currently working.
Building the code on Mac requires that Clang is installed on your system. The easiest way to do this is to get Xcode and install the commandline tools.
After doing that open a terminal and run scripts/mac_build_debug.sh and you should have an executable that you can open in t2-output/macosx-clang-debug-default/ProDBG.app
On Windows Visual Studio 2013 is required (2012 or earlier will not work as parts of the code uses C99) With VS 2013 installed do this:
Open a cmd window and first run scripts\vcvarsx86_amd64.bat and then scripts\win64_build_debug.cmd and you will have an executable in t2-output\win64-msvc-debug-default\prodbg.exe
Currently the Linux build isn't supported but the code complies and all unit-tests should be working correctly. To build use scripts/unix_gcc_build_debug.sh
The current misc work is being tracked on a trello borad which you can find here https://trello.com/b/blg2yGPv/prodbg
