Notes Linux thread compilation undefined reference to ' pthread_create '

When using a thread, when compiling with GCC or ARM-LINUX-GCC, an error occurs: undefined reference to ' pthread_create '

There are two main reasons for this:

1. #include <pthread.h> make sure the header file is added

2,-lpthread compile options, that is, at compile time to add additional compilation options, such as the use of ARM-LINUX-GCC compiled lc300-led-test.c files, the command should be as follows:

Arm-linux-gcc-o lc300-led-test Lc300-led-test.c-lpthread

Note the back-lpthread, especially-behind the ' l ', link = ' l '
