Re: [Boost-users] Boost fusion problem

Hi Lee, We actually noticed that by changing the tuple to a (fusion) vector, it just works. This was unexpected as we'd thought/read in the boost doc that tuple was just effectively an alias for a vector, but apparently not. This is good enough for us so no solution required beyond this.

Hi guys,

We're trying out the latest version of Boost (1.61, migrating from 1.55) and have some code calling the fusion library that now doesn't compile and it's not obvious (to me at least) why. I've created a simple program (below) to demonstrate the issue. As per the compile/run section below, this compiles and runs with Boost 1.55, not with 1.61.

If anyone has any idea or pointers to what is wrong here I'd really appreciate it. Sorry if this isn't the right forum for this kind of issue too - if so please let me know how best to seek help on this.

Regards Jess

This is a regression caused by the upgrades for C++11. Compiling in C++03 mode still works with Boost 1.61. The problem is the nested sequence, the new C++11 version is trying to unpack the inner sequence for a conversion move when it should be moving the entire inner sequence. The problem is caused by the [incorrect dispatch method][0] being selected. Little late for me to attempt a fix, but I should be able to do a bit later this week if no one else can.
