Hi,

Our boost build requires bcp to copy out certain libraries and stage only
the boost modules that we require. However, moving to a new platform,
Solaris 11.3 with SunStudio 12.4, it fails to build the first piece, the
bcp tool.

So, I'm assuming that this is an issue with not picking up the appropriate
standard library. I did have -library=stlport4 as a part of the
user-config.jam.

# Configure sun (default version).
using sun : : : -library=stlport4 -features=tmplife -features=tmplrefstatic
;

This used to work with 1.55.0 on Solaris 10, SunStudio 12.1. Shouldn't the
library flag be seen in the command? Is this no longer a valid rule?

Any ideas what has changed or what I'm missing?

Kevin
