<div><div>Hi,</div>
<div> </div>
<div>as far as I know, lldb can debug windows applications, but there are a</div>
<div>lot of features missing (support for PDB debug info being the most</div>
<div>serious -- i.e. your exe must be built with clang to have any debug</div>
<div>info). You don't need to use any debug server, just do a "target</div>
<div>create", "process launch".</div>
<div> </div>
<div>hope that helps,</div>
<div>pl</div>
<div> </div>
