I have built the latest glibc sources with a ToT GCC and am trying to run the glibc testsuite now. I ran into a couple of
new warnings that I fixed (locally) and am now looking at nptl/tst-thread_local1.cc which dies with:
tst-thread_local1.cc:172:7: error: ‘thread’ is not a member of ‘std’
std::thread thr{[func] {func (nullptr);}};
Does anyone know what is going on here? If I compile a small test program:
#include <thread>
int main(int, char **){
std::thread tt;
}
With G++ 5.4 (using -std=c++11) this test program compiles. but with ToT GCC, it dies with:
g++ -std=c++11 thread.cc -lpthread -o x
thread.cc: In function ‘int main(int, char**)’:
thread.cc:5:5: error: ‘thread’ is not a member of ‘std’
std::thread tt;
^~~
thread.cc:5:5: note: suggested alternative: ‘fread’
std::thread tt;
^~~
fread
Is there some C++ standard change that I am not aware of or some other header file I need to include?
