Codeblock translate boost thread Program

If:

/Usr/lib/libpthread. A (pthread_create.o) | in function 'pthread _ create': |
(. Text + 0xa2f) | undefined reference to '_ dl_stack_flags' |
/Usr/lib/libpthread. A (pthread_create.o) | in function 'pthread _ create': |
(. Text + 0xbe5) | undefined reference to '_ dl_stack_flags' |
/Usr/lib/libpthread. A (ptw-pause.o) | in function '_ pause_nocancel': |

/Usr/lib/libpthread. A (ptw-pause.o) | in function '_ pause_nocancel': |

Solution:

Add libpthread. A to the codeblocks linker settings and find the file in/usr/lib.

The-lpthread parameter must be added to the command line compilation.

GCC thread. C-o thread-lpthread
Thread. C is your source file. Do not forget to add the header file # include <pthread. h>

Add libc. A to the codeblocks linker settings and find the file in/usr/lib.
