linux-tools: perf should link statically to libbfd

[Steve Langasek]

SRU Justification:

Impact: By dynamically linking libbfd, it is not possible to have older versions of the perf tool installed (as there can only be one version of this lib). Also, Debian policy actually forbids depending on a certain version of the library).

Fix: Change the makefile to statically link libbfd. This is a Ubuntu specific change, though. Which unlikely will make it upstream.

Testcase: Check the perf version provided though the builders (it seems that building in chroots can cause builds not linking against libbfd at all as HAVE_CPLUS_DEMANGLE gets set). The ouput of ldd should not show libbfd.

Trying to install linux-tools-2.6.35-28 from maverick on a natty system fails with:

Unpacking replacement linux-tools-2.6.35-28 ...
dpkg: dependency problems prevent configuration of linux-tools-2.6.35-28:
 linux-tools-2.6.35-28 depends on binutils (<< 2.20.51.20100909); however:
  Version of binutils on system is 2.21.0.20110327-2ubuntu2.
dpkg: error processing linux-tools-2.6.35-28 (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 linux-tools-2.6.35-28

This is because perf is dynamically linked to libbfd, and only one version of libbfd (in the binutils package) can be installed at a time. This makes it impossible to install linux-tools for more than one Ubuntu release onto the system at the same time, which is a hindrance to debugging for obvious reasons.

Please link perf statically against libbfd.

See also the binutils-dev package description, which explicitly forbids linking Debian packages dynamically with libbfd:

Package: binutils-dev
Description: The GNU binary utilities (BFD development files)
 This package includes header files and static libraries necessary to build
 programs which use the GNU BFD library, which is part of binutils. Note that
 building Debian packages which depend on the shared libbfd is Not Allowed.

The same thing happened to oprofile several times until it was finally fixed to link libbfd statically (http://bugs.debian.org/537744, http://bugs.debian.org/573905, bug 426614, bug 588033).

[Stefan Bader (smb)]

The provided patch seems incomplete to me. The changed lines only seem to effect any testing, not the build. Though I could see that my own testbuilds were not linking against libbfd, but that turned out to be because HAVE_CPLUS_DEMANGLE is defined. Which actually may be an alternate solution (to modify the builddeps of the kernel package).

Anyway, for a starter, this is the modified Oneiric patch.

[Anders Kaseorg (andersk)]

Yeah, the fixed patch looks right, thanks.

[Stefan Bader (smb)]

Actually, just when you think you understood things, I now see why the old patch seemed to work. What happens is that with those modifications (use /usr/lib/libbfd.a) all compile tests that try to find out whether libbfd, libiberty or libz are there fail. And so we always take the last route of HAVE_CPLUS_DEMANGLE.
Well, the compile works, but I am not really sure whether this is what we want. There certainly is a reason to try libbfd first. Then, while talking about this, there was one idea that, whatever we do, if we could avoid having a Ubuntu specific change to carry around, this would be much less burden to maintain.
There seemed to be an option documented in the makefile (which is to define LDFLAGS="-static") that should result in a static build. Though this seems broken. However, if that can be fixed, that would be something acceptable upstream. So I need to look at that a bit more.
