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.
Q1). https://svn.boost.org/trac/boost/ticket/2100, actually says that threads can be compiled without exceptions. Unfortunately its not the case, as I looked at top-of-trunk codebase and the problem still exists. Is this true? I mean threads require exceptions for a fact that is?. If not then can someone help me how to get it to compile without exceptions, and discard the reset of my email please.
Currently, boost::promise and the other classes from boost/thread/future.hpp require boost::exception_ptr, which requires exceptions. The rest of Boost.Thread can be used without exceptions, but you have to use the individual headers (e.g. boost/thread/thread.hpp, boost/thread/mutex.hpp) rather than boost/thread.hpp Anthony -- Author of C++ Concurrency in Action http://www.stdthread.co.uk/book/ just::thread C++0x thread library http://www.stdthread.co.uk Just Software Solutions Ltd http://www.justsoftwaresolutions.co.uk 15 Carrallack Mews, St Just, Cornwall, TR19 7UL, UK.
