Thanks! readelf -d nss_wins.so.1 Dynamic section at offset 0x1d20 contains 32 entries: Tag Type Name/Value 0x0000000000000001 NEEDED Shared library: [libwbclient.so.0] 0x0000000000000001 NEEDED Shared library: [libwinbind-client-samba4.so] 0x0000000000000001 NEEDED Shared library: [libreplace-samba4.so] 0x0000000000000001 NEEDED Shared library: [libcrypt.so.5] 0x0000000000000001 NEEDED Shared library: [libc.so.7] 0x000000000000000e SONAME Library soname: [nss_wins.so.1] 0x000000000000000f RPATH Library rpath: [/usr/local/lib] 0x000000000000001d RUNPATH Library runpath: [/usr/local/lib] Looking at other libs, they have the settings 0x000000000000000f RPATH Library rpath: [/usr/local/lib/samba4/private:/usr/local/lib] 0x000000000000001d RUNPATH Library runpath: [/usr/local/lib/samba4/private:/usr/local/lib] What is the best way to fix this ? It seems I can do a quick libmap entry and it seems to correct it [/usr/local/lib/nss_wins.so.1] libwinbind-client-samba4.so /usr/local/lib/samba4/private/libwinbind-client-samba4.so libreplace-samba4.so /usr/local/lib/samba4/private/libreplace-samba4.so ldd nss_wins.so.1 nss_wins.so.1: libwbclient.so.0 => /usr/local/lib/samba4/libwbclient.so.0 (0x801003000) libwinbind-client-samba4.so => /usr/local/lib/samba4/private/libwinbind-client-samba4.so (0x801213000) libreplace-samba4.so => /usr/local/lib/samba4/private/libreplace-samba4.so (0x801417000) libcrypt.so.5 => /lib/libcrypt.so.5 (0x80066b000) libc.so.7 => /lib/libc.so.7 (0x80024a000) This is something that needs to be fixed in the port at build time ?
