Ну вот, к примеру:
thresh@snowflake lib/vlc/access $ ldd -r libdvdread_plugin.so
undefined symbol: __block_New (./libdvdread_plugin.so)
undefined symbol: __var_Create (./libdvdread_plugin.so)
undefined symbol: __msg_Generic (./libdvdread_plugin.so)
undefined symbol: __var_Get (./libdvdread_plugin.so)
undefined symbol: vlc_dgettext (./libdvdread_plugin.so)
undefined symbol: config_Duplicate (./libdvdread_plugin.so)
undefined symbol: __config_GetPsz (./libdvdread_plugin.so)
linux-gate.so.1 => (0xffffe000)
libpthread.so.0 => /lib/libpthread.so.0 (0x3aaca000)
libdvdread.so.3 => /usr/lib/libdvdread.so.3 (0x3ab1d000)
libc.so.6 => /lib/libc.so.6 (0x3ab36000)
/lib/ld-linux.so.2 (0x75555000)
libdl.so.2 => /lib/libdl.so.2 (0x3ac4f000)
thresh@snowflake lib/vlc/access $ nm -D /usr/bin/vlc | grep __block_New
thresh@snowflake lib/vlc/access $ nm -D /usr/lib/libvlc.so | grep __block_New
000bcdd0 T __block_New
thresh@snowflake lib/vlc/access $ file /usr/lib/libvlc.so
/usr/lib/libvlc.so: ELF 32-bit LSB shared object, Intel 80386, version 1
(SYSV), stripped
thresh@snowflake lib/vlc/access $ file /usr/bin/vlc
/usr/bin/vlc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.4.1, dynamically linked (uses shared libs), stripped
Это нормально? На момент подгрузки этого plugin'а в программе данные символы
не являются unresolved.
