Dwarf error opening ELF file with GDB 6.3

Dwarf error opening ELF file with GDB 6.3

[Vijay Padiyar]

Hi there

I am building an executable for the MPC8260 processor. I have built my
toolchain for the 2.6 kernel and MPC8260 target using Kegel's crosstool.

When I try to load the built executable in GDB 6.3 (built for my target), I
get a dwarf error.

My compiler flags are:

For C++ files:

~ $
powerpc-603e-linux-gnu-g++  -finline-limit=7000 -fdollars-in-identifiers -DL
INUX -DLIN_HW -D_GNU_TOOL -D__LINUX -D__BIG_ENDIAN__   -fno-builtin  -msoft-
float -mcpu=603e -Wpointer-arith  -Winline -fPIC -ffunction-sections -fdata-
sections   -Wall  -gdwarf-2 -g2 -D_REENTRANT -DGLBTRACELEVEL=7 -DTRACE_RUNTI
ME_LEVEL=7 -DTRACE_CONSOLE_LEVEL=3 -D__cplusplus -fpermissive -fno-for-scope
 -Woverloaded-virtual -fno-rtti -o File.o -c File.cpp


For C files:

~ $
powerpc-603e-linux-gnu-gcc  -finline-limit=7000 -fdollars-in-identifiers -DL
INUX -DLIN_HW -D_GNU_TOOL -D__LINUX -D__BIG_ENDIAN__   -fno-builtin  -msoft-
float -mcpu=603e -Wpointer-arith  -Winline -fPIC -ffunction-sections -fdata-
sections   -Wall  -gdwarf-2 -g2 -D_REENTRANT -DGLBTRACELEVEL=7 -DTRACE_RUNTI
ME_LEVEL=7 -DTRACE_CONSOLE_LEVEL=3    -Wstrict-prototypes -o File.o -c
File.c


My linker options are:

~ $ powerpc-603e-linux-gnu-g++  -g (all object files here) -o Executable.out


Now, when I try to open this file with GDB, I get an error as follows:

~ $ powerpc-603e-linux-gnu-gdb  Executable.out

Dwarf Error: Could not find abbrev number 112 [in module
/home/chandrashekharp/linux/project/devel/5X-Pilot/bin/LINUX/Executable.out]

(gdb)


Could this be due to some incorrect or misdirected compiler flags? Or
something else? Because I am able to load and debug simple applications like
the ubiquitous "Hello, World!" without any problem.

Please help me out!

This error is generally caused by linker bugs, or a corrupt object.
