I have some trouble building the boost filesystem lib using VS2012 x64. I use the following instructions to build it: 1. Download boost 1.54.0 from http://www.boost.org/ 2. Extract files (e.g. "C:\thirdparty\vs2013\x64\boost_1_54_0") 3. Start Visual Studio 2012 x64 command prompt 4. Change to boost directory (e.g. "cd C:\thirdparty\vs2010\x64\boost_1_54_0") 5. Execute .\bootstrap.bat 6. Execute b2 address-model=64 toolset=msvc-11.0 --build-type=complete stage --with-filesystem --with-signals --with-system Unfortunately the file "libboost_filesystem-vc110-mt-sgd-1_54.lib" is not build Previously I used boost 1.51.0, 1.52.0 and 1.53.0. In this releases the libboost_filesystem-vc110-mt-sgd-1_5x.lib was always build without any problems. Did anybody mange to build this lib using VS2012? Which instructions do you use to build it? Best regards, Julian
