More info: g++ & gdb -- works, even without debuginfo for libstdc++ clang++ & gdb -- works g++ & lldb -- works clang++ & lldb -- fails I now notice these warnings in lldb after installing the debuginfo packages: warning: (x86_64) /lib64/libstdc++.so.6 unsupported DW_FORM values: 0x1f20 0x1f21 warning: (x86_64) /lib64/libgcc_s.so.1 unsupported DW_FORM values: 0x1f20 0x1f21 I searched the web for details on that error, but came up empty. Could it be that the debuginfo packages are just not compatible with lldb? > I'd try gdb + gcc + binutils ld (or gold) + libstdc++ (use std::fstream as an > example of something that gcc will home to the libstdc++ debug info - > dwarfdump your executable and you'll see it doesn't contain the definition of > basic_fstream, but verify the debugger can still render the full definition). > If that works, swap out various parts of that & see where it falls apart. Good strategy. I don't quite have the hang of dwarfdump yet though, but I'll continue to investigate. _______________________________________________ cfe-users mailing list cfe-users@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-users
