Hi Adrian,
This is a somewhat non-standard configuration, but there are a couple
of ways you could achieve that. A couple which come to mind are:
- If you're fine with hacking the cmake files then you could just
insert something like
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g0")
into the root llvm CMakeLists.txt
and then add
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g")
to lldb's CMakeLists.txt
- If you want a solution which does not involve modifying the cmake
files, you could build llvm and lldb separately. The llvm could be
built with -g0 (or even in release mode if you really want) and then
the stanalone lldb build would be -g.
- You can also try building with -gsplit-dwarf
(LLVM_USE_SPLIT_DWARF=On) to see if that saves enough space for things
to work for you.
