[CppAD] pthread_getunique_np

[Dominik Skanda]

Hi,

the function isn't available on my system, too. I get the same error
message:

pthread_id.cpp: In function `int main(int, char**)':
pthread_id.cpp:6: error: `pthread_id_np_t' was not declared in this
scope
pthread_id.cpp:6: error: expected `;' before `tid'
pthread_id.cpp:7: error: `tid' was not declared in this scope
pthread_id.cpp:7: error: `pthread_getthreadid_np' was not declared in
this scope

regards
Dominik
