I am trying to port my application to IBM AIX.<br>

I am using boost 1.39 with V10.1 compiler. I have managed to build boost ok.<br>

hence I have &#39;using vacpp ;&#39; in my site-config.jam file<br>

<br>

However when I build my application it barfs with:<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_mutex_unlock<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_mutex_lock<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_mutex_destroy<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_cond_destroy<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_cond_wait<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_cond_broadcast<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_key_create<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_once<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_getspecific<br>

ld: 0711-317 ERROR: Undefined symbol: .pthread_setspecific<br>

<br>

From  googling around the work around is to use xlC_r compiler instead of xlC<br>

<br>

however if change my site-config.jam to &quot;using xlC_r ;&quot; then bjam complains .<br>

<br>

has any one found a workaround for this ?<br clear="all"><br>-- <br>   Best regards,<br>Ta,<br>    Avi<br> <br>
