STRIP 과 gdb
gdb 실행시 아래와 같이 symbol 정보를 load하지 못하는 경우가 있다. 처음에는 ‘-g’ 옵션 또는 최적화 문제 ‘-Ox’ 옵션 문제로 생각했는데, STRIP 을 제거 했더니 정상적으로 symbol enable된 ELF 가 생성되었다. strip의 기능을 제대로 모르고 있었기때문이다.
$ arm-cortex_a9-linux-gnueabi-strip --help
Usage: arm-cortex_a9-linux-gnueabi-strip <option(s)> in-file(s)
Removes symbols and sections from files
The options are:
-I --input-target=<bfdname> Assume input file is in format <bfdname>
-O --output-target=<bfdname> Create an output file in format <bfdname>
-F --target=<bfdname> Set both input and output format to <bfdname>
-p --preserve-dates Copy modified/access timestamps to the output
-D --enable-deterministic-archives
Produce deterministic output when stripping archives
-U --disable-deterministic-archives
Disable -D behavior (default)
-R --remove-section=<name> Remove section <name> from the output
-s --strip-all Remove all symbol and relocation information
-g -S -d --strip-debug Remove all debugging symbols & sections
--strip-dwo Remove all DWO sections
--strip-unneeded Remove all symbols not needed by relocations
--only-keep-debug Strip everything but the debug information
-N --strip-symbol=<name> Do not copy symbol <name>
-K --keep-symbol=<name> Do not strip symbol <name>
--keep-file-symbols Do not strip file symbol(s)
-w --wildcard Permit wildcard in symbol comparison
-x --discard-all Remove all non-global symbols
-X --discard-locals Remove any compiler-generated symbols
