[Gdb-discuss] Dwarf Error: Cannot find referent at offset XXXXXX

Hi all,

I am working on GDB for debugging. Tried with all gdb version and in all cases I am getting Dwarf error. Please tell me how to overcome this error. What I feel that there may be mismatching of dwarf format between ads compiler and gdb. I saw so many numbers of people facing this problem. So tell be very frankly that this problem can be solved or not; otherwise I have to close this project because I am in a deadline. If any where I am doing mistake please tell me how to do this. Once I can able to communicate from host with all commands then I will start writing gdb-stub for target side. I will be waiting for u r reply.

Host Side: PC (Intel P4 with Windows XP OS) with gdb-5.3/gdb-6.0/gdb-6.2

Target Side: ARM926EJ-S based System. Compilation is done through ADS 1.2 compiler.

I tried with all three GDB versions, results r giving below.

1: GDB-5.3 [download from www.sourceforge.net where arm-elf-gdb.exe was in built]

Results: C:\gnude\bin>arm-elf-gdb.exe ...........\........\target.elf

GNU gdb 5.3

2: GBD-6.0 [download from http://ftp.gnu.org/gnu/gdb/ and generating gdb.exe following the steps given in http://gnude.sourceforge.net/ ]

Results: C:\gdb>gdb .......\............\target.elf

(gdb)

3: GDB-6.2 [same as gdb-6.0: (1) $ CFLAGS="-s -O3" (2)export CFLAGS (3)$ mkdir buildgdb; (4)cd buildgdb; (5)../configure --target=arm-elf --prefix=/gnude --disable-shared --disable-nls --disable-win32-registry --enable-interwork --enable-multilib; (6) make all install; this will give gdb.exe in gdb folder]

Results: C:\gdb>gdb ...........\........\target.elf

Conclusion: I expect that u have gone through all the results. Please reply all the necessary steps to do this. The main part is I will proceed or stop here itself.
