GDB

GNU DeBugger je source level debugger pro C, C++ a Fortran. Mß takΘ ΦßsteΦnou podporu jazyk∙ Modula-2 a Chill.

GNU funguje s mnoha rozdφln²mi p°ekladaΦi a na mnoha platformach, ale pokud nepou╛φvßte GCC, debugovßnφ C++ mß n∞kterß omezenφ.

GDB se ovlßdß z p°φkazovΘ °ßdky. Pokud chcete full screen debugger, mßte n∞kolik mo╛nostφ - Emacs GDB mode, xxgdb a gdbtk pod X window, xwpe na textovßm terminßlu, pmgdb pod OS/2, rhdb Φi fsdb pod DOSem apod.

SpustitelnΘ soubory a tabulky symbol∙ jsou Φteny pomocφ knihovny BFS, kterß umo╛≥uje jednΘ kopii GDB podporovat vφce formßt∙ (jako a.out, COFF a ELF). Mß takΘ nap°φklad podporu vzdßlenΘho debugovßnφ p°es seriovou linku nebo TCP/IP, watchpoints (breakpointy, kterΘ se aktivujφ, kdy╛ se dan² v²raz zm∞nφ) apod.

GDB pou╛φvß standardnφ remote interface do simulaΦnφch knihoven jako nap°φklad simulßtory pro ARM, Hitachi H8/300, Hitachi SH a PowerPC.

GDB podporuje cross-debugging. Pokud °ekneme, ╛e GDB "targets" platform, znamenß to, ╛e podporuje cross-debugging pro ni. Pokud °ekneme, ╛e GDB "host" platform, znamenß to, ╛e na nφ m∙╛e b²t zkompilovßn, ale nemusφ nutn∞ debugovat nativnφ programy.
