Re: [Boost-users] Boost.Function in 1.37.0

Actually, there is no code to reproduce this. The errors occur within one of the projects which complies ok with boost 1.36.0. I am not yet sure how does boost.function get referenced through the headers or what might have changed in boost 1.37 compared to 1.36 headers

Could you possibly send a small reproducer code. Since I have a setup of BOOST 1.37 with MSVC, MinGW and on GNU/Linux, I can test it.

Using boost.function in Boost 1.37.0 generates several errors. Compiler extract :

In Boost 1.36.0 the code complies ok. Is it boost function or my code.

Just for note. I am using WinXP with VS2k5SP1 and my projects have had not errors appear when I changed to 1.37. If you can make a copy of your solution and start deleting things until you get to what is causing the problem, that would help quite a bit.
