Nadilson Ferreira created QPID-4279:
---------------------------------------
Summary: Mac OS X thread local storage
Key: QPID-4279
URL: https://issues.apache.org/jira/browse/QPID-4279
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.18
Environment: Mac OS X
Reporter: Nadilson Ferreira
Historically, Mac OS X uses the Mach-O executable format, which does not
support thread local storage data section found on most operating systems using
ELF executable format (here is how ELF handles thread local storage as
documented by Ulrich Drepper). If you try to compile a program using __thread
modifier, you'd get the following error.
error: thread-local storage not supported for this target
The following URL
http://lifecs.likai.org/2010/05/mac-os-x-thread-local-storage.html provides a
good solution for the problem.
Notice also that the file include/qpid/sys/Thread.h defines a macro to handle
the thread local mechanism. Nevertheless some files are not using the macro but
using the __thread instead.

+ src/qpid/sys/posix/AsynchIO.cpp
+ src/qpid/sys/DeletionManager.h
+ src/qpid/sys/epoll/EpollPoller.cpp
