Hi Folks, If this question has been asked already, I apologise, but I have to go back to my group and present the answer. So please bear with me.

In my current project we are using boost extensively, with exceptions disabled, until last week, when I started using boost threads. I get the following error when compiling...

***************

deepsin@deepsin-lnx01:~/code/boost_thread/boost_threads_eg1$ g++ -fno-exceptions -g -I /usr/local/include/boost/ t1.cpp -o t1 -lboost_thread

...

In file included from /usr/local/include/boost/exception_ptr.hpp:9, ? ? ? ? ? ? ? ? from /usr/local/include/boost/thread/future.hpp:14, ? ? ? ? ? ? ? ? from /usr/local/include/boost/thread.hpp:24, ? ? ? ? ? ? ? ? from t1.cpp:3:

/usr/local/include/boost/exception/detail/exception_ptr.hpp:17:2: error: #error This header requires exception handling to be enabled.

...

**************

This means that any header file that includes, thread.hpp can't be compiled with -fno-exceptions. I have couple of questions if someone could help me with, I would appreciate.

It appears that this is due to a dependency of Boost Thread on Boost Exception's exception_ptr. Somebody should look into this and either remove that dependency or add #ifndef BOOST_NO_EXCEPTIONS around the relevant code (unfortunately I don't have time right now to look into this myself.)

Thanks for a response Emil. Do you think you can spare some time for hand holding, so that I can make this change... :) Thanks PS: I love this link on your webpage. http://www.revergestudios.com/reblog/uploads/ReCode/languages1.jpg. Everybody in my group got a kick out of it.
