There is a major difference between linking statically and dynamically. The former only links in object files from .a which resolve currently unresolved symbols, whereas a shared library .so is linked in in its entirety regardless (unless -Wl,–as-needed linker option is used).

It so happens, that GNU C++ standard library std::call_once checks whether the application is multi-threaded by checking whether pthread_create can be resolved. Since your code doesn’t invoke pthread_create or std::thread with non-default constructor, statically linking -pthread doesn’t link in pthread_create , and hence std::call_once fails. The check is done by invoking __gthread_active_p function:

/* For a program to be multi-threaded the only thing that it certainly must be using is pthread_create. However, there may be other libraries that intercept pthread_create with their own definitions to wrap pthreads functionality for some purpose. In those cases, pthread_create being defined might not necessarily mean that libpthread is actually linked in. For the GNU C library, we can use a known internal name. This is always available in the ABI, but no other library would define it. That is ideal, since any public pthread function might be intercepted just as pthread_create might be. __pthread_key_create is an “internal” implementation symbol, but it is part of the public exported ABI. Also, it’s among the symbols that the static libpthread.a always links in whenever pthread_create is used, so there is no danger of a false negative result in any statically-linked, multi-threaded program. For others, we choose pthread_cancel as a function that seems unlikely to be redefined by an interceptor library. The bionic (Android) C library does not provide pthread_cancel, so we do use pthread_create there (and interceptor libraries lose). */ #ifdef __GLIBC__ __gthrw2(__gthrw_(__pthread_key_create), __pthread_key_create, pthread_key_create) # define GTHR_ACTIVE_PROXY __gthrw_(__pthread_key_create) #elif defined (__BIONIC__) # define GTHR_ACTIVE_PROXY __gthrw_(pthread_create) #else # define GTHR_ACTIVE_PROXY __gthrw_(pthread_cancel) #endif static inline int __gthread_active_p (void) { static void *const __gthread_active_ptr = __extension__ (void *) >HR_ACTIVE_PROXY; return __gthread_active_ptr != 0; }

One fix is to #include and add a line or two to the top of your main function:

static_cast(pthread_create); static_cast(pthread_cancel);

That causes undefined references to pthread_create and pthread_cancel and makes -static -pthread link in these functions from the static library into your application, which makes __gthread_active_p function return 1 and, in turn, enables std::call_once to work.

Another fix is to use -Wl,–undefined=pthread_create,–undefined=pthread_cancel linker command line option, which doesn’t require source code changes.

c++ reports terminate called after throwing an instance of’std::system_error’ what(): Unknown error -1 error

In thread programming, the compiler reports

terminate called after throwing an instance of’std::system_error’

terminate called recursively

what(): Unknown error -1

Aborted (core dumped)

Solution: When linking, add the -pthread option. g++ -std=c++11 -pthread thread_demo.cpp -o demo.

This error will be reported when clion is compiled. You need to modify the compilation options in CMakeLists.txt.

c++ terminate called after throwing an instance of ‘std::system_error‘ what(): Unknown error -1

During thread programming, the compiler broadcasts

Terminate called after throwing an instance of ‘STD ::system_error’

you are able to terminate called br> what(): Unknown error-1

Aborted (core dumped)

and add the -pthread option. G++ -std=c++11 -pthread thread_demo.cpp-o demo.

When Clion compiles, this error is reported. You need to modify the compile option at cmakelists. TXT.

Crash : terminate called after throwing an instance of ‘std::system_error’ what(): Resource deadlock avoided

I have a simple client /server application the code of which is mentioned below. Please run the server in one shell and the client in another shell in linux. First start the server and then the client. When the server is done with it’s work, it crashes with following exception:

terminate called after throwing an instance of ‘std::system_error’ what(): Resource deadlock avoided

This happens from the line m_thread->join() from inside the function Service::HandleClient I have no clue on what’s going on.. Can someone please check the code.. I just want that the server application should also get closed correctly the way the client application got closed.

**Server Code : **

c++ terminate called after throwing an instance…anycodings

The signal handler is called in the anycodings_signals context of the thread t. You can’t call anycodings_signals t.join() in the thread routing, it would anycodings_signals cause deadlock, thus you get program anycodings_signals terminate, this way the deadlock is anycodings_signals avoided.
