hello,
I am compiling my code with g++4.8.1 under c++11 mode, however the fedora's system provided boost thread lib has been compiled under c++98.
Linking fails because of errors like:
mainthread.cpp:(.text+0x2cf): undefined reference to `boost::thread::start_thread()**' mainthread.cpp:(.text+0xcc9): undefined reference to `boost::thread::join()'
looking at the provided shared object, nm -C -D /usr/lib64/libboost_thread-mt.**so.1.53.0 |grep start_thread
000000000000ba80 T boost::thread::start_thread_**noexcept(boost::thread_* *attributes const&) 000000000000ba00 T boost::thread::start_thread_**noexcept()
neither of which is start_thread()
I've put an entry here https://bugzilla.redhat.com/**show_bug.cgi?id=1021009<https://bugzilla.redhat.com/show_bug.cgi?id=1021009>
Is there a possible workaround?
Are you sure your compiling with Boost 1.53?
start_thread is defined in boost/thread/detail/thread.h lines 178-184 as
void start_thread() { if (!start_thread_noexcept()) { boost::throw_exception(thread_**resource_error()); } }
Indeed, this file (thread.hpp not .h) is there and has the same code at the same lines. However /usr/lib64/libboost_thread-mt.so.1.53.0 doesn't have start_thread() symbol at all. start_thread_noexcept() is there though.
Fedora guys said they compile with g++4.8 but with c++98, not c++11
Please could you check this file and the contexts of this linenes
