[lldb-dev] about lldb status on windows

[haifeng.qin]

clang++ prompt can't recognize "-fuse-ld=lld" on windows. clang++ version is 3.6 .

command : 
clang ++ -o hello.exe hello.cpp -g -fuse-ld=lld

Is there a problem with my usage?

thanks.

qin.

Make sure you're using lld for the link step by adding the option -fuse-ld=lld.  That will preserve the DWARF debug info, which lldb uses.

 First of all, thank you for your answers.

What type of file generated debug information output to when build exe file? How to generate? 
I use "clang ++ -o hello.exe hello.cpp -g" command generates a pdb and exe.  pdb and exe file format is fixed, how to store debugging information generated by clang?
 
thanks.

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