Re: [lldb-dev] Using LLDB API on windows

[Ted Woodward via lldb-dev]

Hi Russell,

 

I assume you mean for SBTarget::Launch or LaunchSimple to launch a Windows 
application.

 

The short answer is, this already works.

 

SBTarget::Launch calls Target::Launch, which calls DebugProcess in the relevant 
platform. For cases where we use lldb-server, the platform make a call that 
eventually gets to  GDBRemoteCommunication::StartDebugserverProcess to start up 
lldb-server. On Windows, PlatformWindows::DebugProcess calls Process::Launch, 
which (on Windows) will do the correct thing to start up and connect to a 
Windows process.

 

See PlatformWindows::DebugProcess in 
source\Plugins\Platform\Windows\PlatformWindows.cpp and 
ProcessLauncherWIndows::LaunchProcess in 
source\Host\windows\ProcessLauncherWindows.cpp .

Subject: [lldb-dev] Using LLDB API on windows

 

Hey so I am developing a project using LLDB as a debugger and am looking to 
make it cross-platform. 

 

As I see it, the LLDB API boots up an instance of lldb-server, but lldb-server 
isn't available on windows. Is there a way to use the LLDB C++ API on windows? 

 

On the status page   I see the lldb 
commandline tool is OK for windows, which uses the LLDB API, how is this 
achieved?

Re: [lldb-dev] Using LLDB API on windows

[Russell Greene via lldb-dev]

That makes sense, and I'm sure it works great when using MSVC as a
compiler, but I think LLDB recognizes mingw as a unix compiler and tries to
do GDBRemoteCommunication::StartDebugserverProcess when it should be doing
PlatformWindows::DebugProcess.

Not sure though. All I know is when I try to do a SBTarget::Launch on
windows under mingw (msys2) it says cannot find lldb-server...

Re: [lldb-dev] Using LLDB API on windows

[Ted Woodward via lldb-dev]

I wonder if lldb isn’t using the windows platform. In the lldb command line, 
load up your target, then type “target list”. I’d like to see what plaform it 
chose, and what the triple is.

[lldb-dev] Temporary log channel...

[Jim Ingham via lldb-dev]

BTW, Jason noticed that somebody had deleted the LIBLLDB_LOG_TEMPORARY log 
channel.  

Since it looks like one of those things that there's no use for, it's easy to 
think deleting it is a good cleanup.  But it's actually quite useful as a way 
to quickly tailor-make a particular set of logs.  Some of the logs (the 
expression log in particular) are pretty chatty and you just want a subset, and 
sometimes you want to pick just a few messages from several logs.  You can 
easily do that by just switching the log channel from whatever log it was to 
LIBLLDB_LOG_TEMPORARY, and then do "log enable lldb temp".  Then before you 
check in your code, you can just go revert all the instances of 
LLDB_LOG_TEMPORARY and you've left the original state untouched.

Re: [lldb-dev] Using LLDB API on windows

[Zachary Turner via lldb-dev]

As the person who added most of the support for debugging Windows
executables, I can tell you that I never tested a MinGW executable (nor was
it one of my original goals).  It doesn't entirely surprise me that things
are behaving this way, but I'm not sure what the exact cause would be off
the top of my head.  MinGW executables and msvc Win32 executables use an
entirely different ABI, so I would exepct the non lldb-server path to be a
little wonky since I always assumed MSVC ABI in my implementation.  On the
other hand, as you said there is no lldb-server.

If you're interested in digging into the source code and trying to add a
patch for MinGW support, I can give you some pointers.

[Russell Greene via lldb-dev]

Ooh, I'd definitely be interested.

Sounds like a very fun project.

I'll have to familiarize myself with the internals (I'm currently learning
the API, which seems to resemble the internals moderately well...)

I'll start educating myself tomorrow morning when I wake.
