    Hi,

    I am building cairo-1.8.6 in AIX 6.1.
    After the configuring was successful, i gave make command.

    The following error is displayed.
    libs/libcairo.exp -W1, -bernotok
    Undefined symbol: pthread_mutex_lock
    Undefined symbol: pthread_mutex_unlock
    Undefined symbol: pthread_mutex_destroy
    Use the -bloadmap or -bnoquiet option to obtain more information.
    Collect2: ld return 8 status.

    What does this means and how to resolve it.

    Please help.

    It is missing the pthread library.
    This contains the three missing function.

    The .exp means this is some form of export file used to build the program and it is missing the references to the library.

    Hope this helps, Nigel
