Dear Boosters!
I already posted this message to boost-users lists last week but I got no response. So here we are.
I have a problem compiling some source code that uses Boost 1.54 and gcc 4.2.3 (it's a toolchain for a MIPS platform but that's irrelevant).
Basically there is a problem with checking concepts on types that come from unnamed namespaces. See the attached code example and compiler error message. Note that the same code compiles without any problems on gcc 4.6.3.
I've found a question on boost-dev list [1] and a ticket [2] related to this particular issue. Note that the ticket was closed with "worksforme" resolution, which I don't understand - the problem is still out there.
Now since Boost's minimal requirements are gcc 3.3 [3] then should I consider it a bug that I should report or is it a known issue? In case the latter is true then what should I do?
Not sure that this particular problem is triggered by the same bug I experienced [1], but I'd say anonymous namespaces are quite broken in gcc 4.2. I'm not aware of any workaround other than just replace the anonymous namespace with a named one and a using declaration. [1] http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28407
