             Bug #: 30862
           Summary: New prelink is required for debug builds
           Product: Wine
           Version: 1.4
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: build-env
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: wrar at wrar.name
    Classification: Unclassified


At least on current Debian unstable with gcc 4.7.0 and at least with the Debian
1.4 package (which includes -g in CFLAGS) kernel32.dll.so cannot be relocated
with prelink older than the latest release (20111012):

prelink: kernel32.dll.so: Unknown DWARF DW_AT_8465 with block DW_FORM

You can see this message in our build logs at e.g.
https://buildd.debian.org/status/fetch.php?pkg=wine&arch=i386&ver=1.4-0.4&stamp=1338858761

It may be not clear from the message but prelink actually exits without
changing the binary so kernel32.dll.so is not relocated which causes all bugs
that was fixed by adding the relocation.

Support for "DW_AT_8465" which is DW_AT_GNU_call_site_value was added to
prelink in r188 on 2011-04-01 so at least in some cases if you build wine with
debug, you are required to use prelink >= 20111012, otherwise you deserve the
same configure warning that is issued when prelink is not installed.
Unfortunately I don'see an easy way to check the prelink binary version as they
all report "prelink 1.0" in -V.

When wine is built with gcc 4.6.3 prelink fails on DW_OP_242
(DW_OP_GNU_implicit_pointer) instead which was added in the upstream r187 on
2010-11-23 (so 20111012 is still required). When wine is built with gcc 4.5.3
prelink 20090925 doesn't fail. This may be the real cause of "Steam overlay
requires gcc 4.5" reports such as #22053.
