[lttng-dev] Odd dependency for lttng-ust

[lttng-dev] Odd dependency for lttng-ust

[Thibault, Daniel]

I'm starting from a clean Ubuntu 12.04 installation after adding the various prerequisites of the git.lttng.org LTTng 2 packages:

LTTng 2 Packages (in the proper dependency order):

lttng-modules (2.1.0+-c6403de)
userspace-rcu (0.7.6-da9bed2)
lttng-ust (2.1.0+-340f776)
lttng-tools (2.1.1+-281047b)

Prerequisites installed:

automake
binutils-gold
bison
flex
libpopt-dev
libtool
libuuid1
python-dev
swig2.0
kernel's headers (i.e. linux-headers-generic)
texinfo
g++

After making and installing lttng-modules and userspace-rcu successfully, lttng-ust's configure fails with:

checking for _cds_lfht_new in -lurcu-cds... no
configure: error: Cannot find
liburcu-cds lib, part of Userspace RCU 0.7 or better.

This occurs even though userspace-rcu installed /usr/local/lib/liburcu-cds.  It seems I must install liburcu-dev from the LTTng PPA (because the current Ubuntu liburcu-dev is 0.6.7 while lttng-ust requires 0.7 or better) before I can configure lttng-ust properly.  This is a weird bootstrapping problem: could the userspace-rcu package's install be incomplete?

Quoting the lttng-tools README file:

"    - liburcu
      Userspace RCU library, by Mathieu Desnoyers and Paul E. McKenney

      -> Tested with liburcu >= v0.7.2"

Therefore you need to install Userspace RCU 0.7.2 or later.

A dependency is not only on a package, but also on a range of versions.

Thanks,

Mathieu

   But shouldn't the userspace RCU library be installed by the userspace-rcu package?  That's the gist of my puzzlement.  By the time I get to lttng-ust's configure, I've installed lttng-modules and userspace-rcu.  Doing an install of git.lttng.org's userspace-rcu should be equivalent to installing the liburcu-dev package from repository, no?

No. Distribution packages usually lag behind the project upstream.
Ubuntu 12.04 has been released last year, and their policy don't allow
them to update the packages within this specific distribution version.

This is why you run into trouble when you try to mix distribution
packages (from last year) with the current development head.

Don't mix packages from distributions with packages built from sources
when version dependencies don't match. All the required dependency
information is found in the README files of each project.

Thanks,

Mathieu

But I'm not mixing old packages with new: I tried fetching everything from git.lttng.org.  The README for lttng-ust reads in part:

PREREQUISITES:
  - liburcu
    Userspace RCU library, by Mathieu Desnoyers and Paul E. McKenney
    -> This release depends on liburcu v0.7.2
      * Debian/Ubuntu package: liburcu-dev
      * Website:  http://lttng.org/urcu
      * Releases: http://lttng.org/files/urcu
      * GitWeb:   http://lttng.org/cgi-bin/gitweb.cgi?p=userspace-rcu.git;a=summary
      * Git:      git://lttng.org/userspace-rcu.git

Doesn't this say that I can get the required liburcu from git.lttng.org's userspace-rcu?  Could it be version 0.7.6 is not retro-compatible with 0.7.2 (that is to say, lttng-ust requires 0.7.2, and 0.7.2 only, not "0.7.2 or later")?

0.7.6 should work. You might want to check the list of packages
installed by your distribution to see if an old userspace RCU package is
installed into /usr/ and overrides the one you installed within
/usr/local/.

   But 'sudo make install' invokes 'ldconfig -n /usr/local/lib'...

   Tried again, without fetching liburcu-dev from the LTTng PPA.  The packages added to the basic Ubuntu 12.04 install are:

automake        1:1.11.3-1ubuntu2
binutils-gold    2.22-6ubuntu1

This time I did sudo ldconfig after each install (both commands had nothing to say).  After making and installing lttng-modules and userspace-rcu successfully, lttng-ust's configure fails about a dozen checks earlier than the liburcu-cds check with:

checking for uuid_generate in -luuid... no
checking for uuid_create in -lc... no
configure: error: Cannot find libuuid uuid_generate nor libc uuid_create. Use LDFLAGS=-Ldir to specify their location.

Even though libuuid1 (includes libuuid-perl, uuid-dev, uuid-runtime) is installed.  I need to fix this new stumbling block before we can address the liburcu-cds problem.

As the error messages suggests, please try:

LDFLAGS=-L/usr/local/lib ./configure

instead of "./configure"

   Interesting, that prefix does allow configure to complete successfully.  lttng-tools runs into the same problem as lttng-ust, and requires the same LDFLAGS prefix for its configure.  No other problems arise.

   So how do we fix userspace-rcu so the bootstrap -configure - make - install sequence doesn't run into this problem?  I'm presuming here that userspace-rcu's install needs to be touched up.  Or maybe lttng-ust's (and lttng-tools's) bootstrap.

   (It's a problem because the ReadMe for the lttng-ust and lttng-tools packages stipulate a plain ./configure invocation: as they currently stand, the instructions fail)

[lttng-dev] Odd dependency for lttng-ust

Hi Daniel,

Could you make sure that all previous liburcu versions are properly
uninstalled (e.g. no liburcu* in /usr/lib)?

I think that you might have an old version installed and that
configure is looking up the library via the default LD_LIBRARY_PATH
which contains /usr/lib before /usr/local/lib and hence you see the
error that "checking for _cds_lfht_new in -lurcu-cds no" even though a
newer version is present in /usr/local/lib.

As a general guideline, make sure when you install packages from
source that you uninstall previous version that might have been
installed by your package manager in order to minimize potential
conflicts.

Christian
