Can't compile lldb on opensuse 12 64

Hello,

I can’t compile lldb on opensuse linux 12 64bit.

I get many warnings and the error:

(Almost full log available.)

The configure I used:
configure --enable-cxx11--enable_optimized --disable_assertions

I could compile the latest clang++, libc++ etc. Only lldb won’t compile.

Any ideas?

Thanks

I don't think you're doing anything wrong - it looks like an extra
parameter was added to the call and this case was missed.

Can you try passing in the file size ( filespec.GetByteSize() ) as the 3rd
parameter in linux/Host.cpp and see if that this fixes it?

Oh this is the fix I just sent. If you review rev 186211, it just needs a 0 there.

Yeah, there's a bit of code in ObjectFile::GetModuleSpecifications() which does the FileSpec::GetByteSize() call for you if you pass in a 0 as a part of r186211 -- I committed Timothee's patch. Thanks!
