- Subject: Dwarf error opening ELF file with GDB 6.3
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!
