That was a dead end. Recent boost appears to assume that the STL headers are provided by the system. I'll probably have to switch back to bundled boost and use its TR1 headers. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org
