arm-elf-gcc and objdump

["Aaron Case" <aaron dot case at dynazign dot com>]

Hello,

I am having trouble with a simple debugging switch in arm-elf-gcc.

I include the -g switch in the make file compiler flags like such:

CFLAGS
= -g -Wall -I$(PKG_INSTALL_DIR)/include -ffunction-sections -fdata-sections

I get the following output, which shows it took the -g switch, when I build
the project files for an application called "basic_lcd::

$ make
arm-elf-gcc -c -o
basic_lcd.o -g -Wall -I/ecos-c/ECOS_db/ecos_min_v2_install/inc
lude -ffunction-sections -fdata-sections basic_lcd.c

Yet when I run the arm-elf-objdump binary utility I get the following
output:

$ arm-elf-objdump -g basic_lcd

basic_lcd:     file format elf32-littlearm

arm-elf-objdump: basic_lcd: no recognized debugging information

In addition I can see a size difference in the files when compiled with and
without the -g switch for debugging.

I can see that the debugging switch is adding information to the file, yet
the extra information is not recognized as debugging information.

If anyone has any experience with this, thanks in advance for your hints and
help.

Regards,
Aaron Case
