On AIX I want to compile with multi-threading, then means using xlC_r.

Using bjam threading=multi

Will do this.

However is there a way achieving the same effect without putting "threading=multi" on the command line ? i.e putting the threading model in site-config.jam

In my site-config.jam , have tried the following, all to no avail

*using* xlc : : xlC_r ; using vacpp : : <threading>multi ; using vacpp : xlC_r ;

Use project requirements: project site-config : requirements <threading>multi ; - Volodya
