Benjamin Bannier commented on MESOS-6658:
-----------------------------------------
One crucial difference between the cmake and the autotools build is that the
autotools build explicitly requests {{-Wl,--as-needed}} under Linux, while the
cmake build just inherits the default behavior of the linker. AFAIK e.g.,
Fedora enable {{-Wl,--as-needed}} systemwide and by default, while e.g.,
Debian-based distros (Debian & Ubuntu) do not. This seems to nicely overlap
with were these bad binaries are created.
To test this out I added {{-Wl,--as-needed}} to the
{{CMAKE_SHARED_LINKER_FLAGS}} on a ubuntu-14 host, and was indeed able to
unload a {{src/mesos-tests}} created with the cmake setup successfully.
I am not sure this is a problem in the cmake build; it seems more that the
autotools build explicitly masks a problem, and we see that only in the cmake
build which didn't behave identical. It seems desirable to have the build
produce good binaries no matter whether {{-Wl,--as-needed}} was used or not, as
e.g., some systems use versions of {{ld}} which overeagerly might drop even
required dependencies (e.g., in cases where dependencies do not model their own
dependencies correctly).

> A default cmake build created from {{ec0546e}} creates a {{mesos-tests}}

> This problem appears e.g., ubuntu-14.04 with cmake-2.8.12, but also on
