About
This project elfdbg is a utility program to quickly identify if an ELF binary is built with debug sections
Debug sections in ELF binary usually are generated using the -g
flag with the
compiler. The compiler adds the new .debug_*
sections in the binary.
The program is looking for the existence of sections with name starting with .debug_
to determine if the binary has been built with debug information.
The ELF format is a well-known standard. ELF TIS reference specification is available here and as a FreeBSD elf(5) man page.
Usage
This is intented to be used in shell script in order to avoid using file(1) and parsing the output like below:
`file /path/to/binary | awk '/debug_info/{print $2}'` != 'ELF'
To determine if binary has been built with debug, use the following:
if elfdbg -q /path/to/binary; then echo "No symbols" else echo "Binary with debug symbols" fi
On FreeBSD, you can easily identify the binary packages with missing debug using similar one-liner:
pkg info -a -l|grep local/bin/|while read a; do echo $a: `elfdbg $a`; done
Build and install
The Makefile use the standard BSD Makefile to build the program.
make && sudo make install
If your on Linux, use make -f GNUMakefile
to specify the GNU Makefile.
Test
The tests cases are implemented using the FreeBSD test suite framework with kyua and Kyuafile .
make test
