... Just wanted to add that the same problem occurs when I try the piece of code in the documentation of Boost 1.42: http://boost.org/doc/libs/1_42_0/doc/html/proto/users_guide.html#boost_proto... --- On Fri, 24/12/10, Hossein Haeri wrote: From: Hossein Haeri Subject: [Boost-users] [Proto] Error in FoldToList Example of Tutorial To: boost-users@lists.boost.org Date: Friday, 24 December, 2010, 17:13 Dear all, When I compile the FoldToList example defined here in Proto tutorial: http://boost.org/doc/libs/1_45_0/doc/html/proto/users_guide.html#boost_proto... I get some compiler error message in GCC 4.5.1 (MinGW32, WinXP, SP3), Boost 1.42.0. For your reference, I have included the error messages in the P.S. section of this posting. Anyone here knows what's going wrong?
