First time posting to a mailing list, sorry if I've messed something up. I'm trying to build Boost 1.48 using Intel XE 12.1 and when running bjam it brings up "Windows can't open this file" for each file. I tried to adapt instructions from here: http://software.intel.com/en-us/articles/building-boost-with-intel-c/ I added the following to user-config.jam: using intel-win : 12.1 : "C:/Program Files (x86)/Intel/Composer XE/bin/ia32/icl.exe" : intel "C:/Program Files (x86)/Intel/Composer XE/bin/iclvars_ia32.bat" ; I tried building with the following command: C:\Users\blanked\Desktop\boost_1_48_0>bjam --toolset="intel" "-sINTEL_PATH=C :\Program Files (x86)\Intel\Composer XE\bin\ia32\" "-sINTEL_BASE_MSVC_TOOLSET=vc -10_0" "-sINTEL_VERSION=12.1" Building the Boost C++ Libraries.
