Вопрос по gdb, gcc – Сообщение об ошибке GDB (GCC 4.7) (из macports)


У меня есть такое сообщение, когда я запускаю GDB:

$ gdb a.out

Кажется, мне нужно снова получить libstdc ++, но как с macports?

GCC now generates unwind info also for epilogues. DWARF debuginfo generated by GCC now uses more features of DWARF3 than before, and also some DWARF4 features. GDB older than 7.0 is not able to handle either of these, so to debug GCC 4.5 generated binaries or libraries GDB 7.0 or later is needed. You can disable use of DWARF4 features with the -gdwarf-3 -gstrict-dwarf options, or use -gdwarf-2 -gstrict-dwarf to restrict GCC to just DWARF2, but epilogue unwind info is emitted unconditionally whenever unwind info is emitted.

Так что вы должны увидеть, есть ли в Macports более новая GDB.
