the dpkg-shlibdeps pacakging tool warns about some under- and overlinked libraries:
symbol _Ux86_64_dwarf_find_unwind_table used by libunwind-coredump.so.0.0.0 found in none of the libraries symbol _Ux86_64_get_elf_image used by libunwind-coredump.so.0.0.0 found in none of the libraries symbol _Ux86_64_dwarf_search_unwind_table used by libunwind-coredump.so.0.0.0 found in none of the libraries symbol _Ux86_64_dwarf_search_unwind_table used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol _Ux86_64_get_elf_image used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol lzma_index_uncompressed_size used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol lzma_index_end used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol lzma_index_buffer_decode used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol _Ux86_64_dwarf_find_unwind_table used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol lzma_stream_footer_decode used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol lzma_index_size used by libunwind-ptrace.so.0.0.0 found in none of the libraries symbol lzma_stream_buffer_decode used by libunwind-ptrace.so.0.0.0 found in none of the libraries The following patch addresses these: src/Makefile.am - define PTRACE_SO - add libunwind-ptrace.la and libunwind-coredump.la last to lib_LTLIBRARIES to fix build errors with the new LIBADD dependencies. - define libunwind_ptrace_la_LDFLAGS and libunwind_ptrace_la_LIBADD - define libunwind_coredump_la_LIBADD - remove libunwind-$(arch).la from libunwind_setjmp_la_LIBADD Matthias
liblzuma used in decoding MiniDebuginfo is not listed in libunwind.pc. Changes in version 2 of patch: * Don't check HAVE_LZMA. It is redundant. * Make liblzma as private libraries in use. Both are suggested by Mike Frysinger <[email protected]>.
