I would like to add stack traces to my program (Cygwin/MinGW, Windows XP). I've already implemented a stack walker, but there is an open problem with symbol name/line lookup. The compiler (GCC 4.4-trunk) emits DWARF2-compatible debug information, but I don't know how to reach the appropriate sections (especially ".debug_info") within the executable. The PE header walker is able to dump PE sections, but they have strange, numeric names, e.g.:
sec[0]: name = .text sec[1]: name = .data sec[2]: name = .rdata sec[3]: name = .bss sec[4]: name = .idata sec[5]: name = /4 sec[6]: name = /19 sec[7]: name = /35 sec[8]: name = /47 sec[9]: name = /61 sec[10]: name = /73 sec[11]: name = /86 sec[12]: name = /97 sec[13]: name = /108 On the other hand, the DWARF sections are available in the file -- a hexdump viewer can locate them, as well as objdump. Could somebody please tell me what should I do in order to get to the DWARF sections from this point? Any documentation will be appreciated. Best regards, Piotr Wyderski
