On a fresh ubuntu install, after configuring everything. I get an error
terminate called after throwing an instance of 'std::system_error'
what(): Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)
This error seams to come from a lack of the option -lpthread for the compiler. However, cmakefiles seem to be adding this option.
I tried to add it manually with -DCMAKE_CXX_FLAGS=" -lpthread " but that did not work either.
Excuses, ik kende de bug al, maar dacht dat er niet meteen iemand anders op gcc 4.8 ging beginnen werken (dus had hem nog niet gefiled). Dit is een gekende bug in ubuntu / gcc 4.8, dus wachten op hun fix.
Meer gedetailleerd: er is een optimalisatie toegevoegd/aangepast die libraries niet linkt als de compiler/ubuntu denkt dat ze niet nodig zijn, zelfs als ze in de linker flags staan. Die detectie is dus verkeerd :)
Ubuntu versoin of the bug https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1228201 Workaround: compile with -Wl,--no-as-needed
added a temporary fix for the problem with compiling on new ubuntu
See #571. This commit should be reverted as soon as g++ or ubuntu fixes their bug.

Does not seem to be getting fixed anytime soon.
Further info: Cmake warned me (but did not give an error)
-- Looking for include file pthread.h -- Looking for include file pthread.h - not found -- Could NOT find Threads (missing: Threads_FOUND)
Might have something to do with my specific cmake version: see http://stackoverflow.com/questions/16909008/cmake-error-try-compile-pthreads-of-type-executable
