Hello List. The attached file contains the errors I get when I attempt to compile my utilities library using Boost 1.47.0 with the Intel Compiler v12.1.0 on Debian Squeeze v6.0.2. (My IDE is Qt Creator v2.3.0 using v4.7.4 (x64) SDK) This is my first attempt at doing this under Linux as the utilities library (dll) compile as is in Windows. So I would appreciate your thoughts on this as I can't continue the migration of the other projects until I get this library working. Thank you. -- Bill
