Subject: [PATCH] Don't issue errors on GDB Python files
Many packages, including GCC, install Python files for GDB in library
diretory. ldconfig reads them and issue errors since they aren't ELF
files:
ldconfig: /usr/gcc-5.1.1/lib/libstdc++.so.6.0.21-gdb.py is not an ELF file - it has the wrong magic bytes at the start.
ldconfig: /usr/gcc-5.1.1/libx32/libstdc++.so.6.0.21-gdb.py is not an ELF file - it has the wrong magic bytes at the start.
ldconfig: /usr/gcc-5.1.1/lib64/libstdc++.so.6.0.21-gdb.py is not an ELF file - it has the wrong magic bytes at the start.
This patch silences ldconfig on GDB Python files by checking filenames
with -gdb.py suffix.
[BZ #18585]
* elf/readlib.c (is_gdb_python_file): New.
(process_file): Don't issue errors on filenames with -gdb.py
suffix.
