Just a suggestion:

new gcc compiler requires that library follows the object.

Example:

gcc pthread_example.c -lpthread

instead of

gcc -lpthread pthread_example.c

Not exactly sure what you are compiling but the order the compile command is entered has been known to cause issues in new gcc.

Good luck
