It's the libstdc++-4.9-dev in Debian Jessie (amd64). The package version is 4.9.2-10.<br>

Which C++ library is that? On my system (gcc 4.9) running<br>
<br>
grep -r '&pthread_create' /usr/include/c++/<br>
<br>
finds nothing.<br>
<br>
And in the preprocessed file:<br>
<br>
$ grep pthread_create SymbolTable.ii<br>
extern int pthread_create (pthread_t *__restrict __newthread,<br>
static __typeof(pthread_create) __gthrw_pthread_create __attribute__<br>
((__weakref__("pthread_create")));<br>
return __gthrw_pthread_create (__threadid, __null, __func, __args);<br>
<br>
<br>
Cheers,<br>
Rafael<br>
