mongodb @2.6.4 fails to build with boost 1.56.0

[moneyc.net@…]

Trying to install mongodb results in this error:

Please attach the main.log, but I believe this may be an issue I already reported to the developers.

I guess this is what I am observing as well. I'll attach a main.log.

Thanks. The error in both logs is:

:info:build src/mongo/shell/linenoise_utf8.h:145:14: error: no member named 'swap' in namespace 'std'; did you mean 'boost::swap'?

This is reported upstream: ​https://jira.mongodb.org/browse/SERVER-14930

This may be an incompatibility with boost 1.56.0. We could go back to using the copy of boost shipped with mongodb, but that would reintroduce #38334. In the mean time, until we work out a more permanent solution, you could downgrade to boost 1.55.0.

Cc Me!

At the expense of perhaps reintroducing #38334, I've switched the mongodb port to use the built-in copy of boost again in r124301.
