From: fin_engr@hotmail.com To: boost-users@lists.boost.org Subject: FW: boost -mt libraries in cygwin Date: Sun, 25 Sep 2011 10:15:28 -0400 hi, I just built and installed boost using the following on cygwin ./bootstrap.sh --with-libraries=chrono,date_time,exception,filesystem,graph,graph_parallel,iostreams,math,program_options,random,serialization,signals,system,test,thread,wave link=static link=shared threading=single threading=multi then I ran the below, ./b2 --layout=tagged and the message indicated that it: failed updating 2 targets and skipped 7 targets.... but I continued and ran./b2 --layout=tagged install however, I look in /usr/local/lib and I only have those libraries with suffix -mt My programs are looking for the libraries without the -mt suffix. Can you please let me know what I need to do to get those libraries. thanks!
