-----------------------------------
Summary: With unbundled dependencies Mesos doesn't build with
-Wl,--no-copy-dt-needed-entries
Key: MESOS-2486
URL: https://issues.apache.org/jira/browse/MESOS-2486
Project: Mesos
Issue Type: Bug
Components: build
Affects Versions: 0.22.0
Environment: Ubuntu 14.10
Reporter: Cody Maloney
Assignee: Cody Maloney
Priority: Blocker
To build a module, glog, protobuf, and boost need to be unbundled so they can
be used by both the module as well as Mesos.
In a bundled build, we build the libraries into libmesos.la / libmesos.so, so
every program picks them up.
In unbundled dependencies are used, we link against all of the dynamic
libraries / .so files manually. We link libmesos.so against them, then link all
the other programs against libmesos.so to get the dependencies.
This relies on the DT_NEEDED flag "copying" the .so's dependencies into the
executable. [Ubuntu and
Debian|https://wiki.ubuntu.com/ToolChain/CompilerFlags#A-Wl.2C--no-copy-dt-needed-entries]
forcibly add the flag `-Wl,--no-copy-dt-needed-entries` to the linker to
disable this.
This breaks the build with unbundled dependencies on those platforms. Some
sample error messages:
{code}

'_ZN6google4base21CheckOpMessageBuilder7ForVar2Ev'
