Hi! Some libraries (e.g. /usr/lib/libaio.so.0) don't have any DT_NEEDED entries because they don't have any relocations against any libraries but self. Such libraries haven't been prelinkable so far, because ld.so prints statically linked for them. This patch just moves the DT_NEEDED check after DL_DEBUG_PRELINK check, it looks big because of indent changes (diff -upb is very short). 2003-05-14 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (dl_main): For LD_TRACE_PRELINKING print search scope even ifno DT_NEEDED is present. --- libc/elf/rtld.c.jj 2003-05-13 16:58:06.000000000 -0400 +++ libc/elf/rtld.c 2003-05-14 17:12:35.000000000 -0400 @@ -1262,57 +1262,52 @@ cannot allocate TLS data structures for important that we do this before real relocation, because the functions we call below for output may no longer work properly after relocation. */ - if (!
