Bisection indicates that r81808 is the responsible change, though I've no idea why.

I encountered the same error message. I used bcp with the --scan option, then I used bcp again and copied over the build module. Bootstrap ran fine, but I got the same error as listed above. It was fixed after I copied over the directory .../boost_1_54_0/libs/system/build to the stripped out boost directory that bcp copied the files to.

but I got the same error as listed above when I ran b2. *

I've discovered while looking at Boost 1.55.0 Beta 1, that the regular expressions in bcp have to be updated to account for the BOOST_SYSTEM_NOEXCEPT macro. I'll attach the diff shortly.

Still seems to fail for me, in what appears to be the same way. I updated to the latest revision, and that is r86530 (with matching comment), and I get the same failure. (The build was using gcc-4.8 since that's now the default. Likely originally it was using gcc-4.7.)

Ah.... it works if you do a

./b2 --with-filesystem

Or else build from within libs/filesystem/build.

Why a global build fails I have no idea, and frankly my attempts to get meaningful diagnostic information from Boost.Build have completely failed :-(

Given that we're going to be modularizing Boost anyway, I hope this issue will become moot eventually?

I'm still encountering this error with Boost 1.56.0 on Ubuntu 12.04 LTS with gcc 4.6.3

In fact, in order to even /get/ to this stage, I have to do a lot more with bcp that the original poster suggests. I summarised my efforts on Stack Overflow here: http://stackoverflow.com/questions/26132227/how-do-i-use-bcp-to-extract-a-subset-of-boost-which-can-be-built (including referencing this ticket)

Any advice to proceed further would be appreciated.
