我尝试使用std :: this_thread :: sleep_for()函数,但得到了错误
error: 'std::this_thread' has not been declared
。
标志_GLIBCXX_USE_NANOSLEEP包括。
还需要什么来强迫它发挥作用?
MinGW ==> gcc版本4.7.2(GCC)
SSCCE:
#include<thread>
int main() {
std::this_thread::sleep_for(std::chrono::seconds(3));
}
命令行:
g++ -D_GLIBCXX_USE_NANOSLEEP -std=gnu++0x ssce.cpp -o ssce.exe
编译结果:
ssce.cpp: In function 'int main()':
ssce.cpp:4:8: error: 'std::this_thread' has not been declared
