Hi all,

For some reason, ld report some undefined symbols when building the shared library libselinux.so.1 on bfin.

[...] -Wl,-soname,libselinux.so.1,-z,defs,-z,relro

callbacks.c:(.text+0x82): undefined reference to `_security_check_context'
callbacks.c:(.text+0x92): undefined reference to `_is_selinux_enabled'
label.c:(.text+0x172): undefined reference to `_selinux_raw_to_trans_context'

label_file.c:(.text+0xa4c): undefined reference to `_selinux_file_context_path'
label_media.c:(.text+0xf2): undefined reference to `_selinux_media_context_path'
label_x.c:(.text+0xee): undefined reference to `_selinux_x_context_path'
mapping.c:(.text+0x25a): undefined reference to `_avc_reset'
sestatus.c:(.text+0x17e): undefined reference to `_security_getenforce'
sestatus.c:(.text+0x214): undefined reference to `_security_deny_unknown'
collect2: ld returned 1 exit status

All missing symbols are defined in selinux_internal.h or avc_internal.h
by hidden_proto() which is defined in src/dso.h.

hidden_proto() add some asm code which depends on architecture:
# if defined(__alpha__) || defined(__mips__)
#  define hidden_def(fct) \
     asm (".globl " #fct "\n" #fct " = " #fct "_internal");
# else
#  define hidden_def(fct) \
     asm (".globl " #fct "\n.set " #fct ", " #fct "_internal");
#endif

I suppose this asm code is not supported on bfin.
Maybe disable libselinux on bfin ?

Best regards,
Romain Naour
