Hi, I've been playing aournd with boost coroutines2 and maybe I'm just confused about where this project is, but with 1.65 coroutines2 doesn't seem to be buildable out of the box any longer: I've tried looking through mailing list archives for anything about the status of coroutine2 to no avail, and coroutine still spits out warnings to use coroutine2 when used. I'm not sure where in the build system things hook in to fix this. Here's the output on my system: berne@Bugg:~/tmp$ tar xzf boost_1_65_0_beta1_rc1.tar.gz berne@Bugg:~/tmp$ cd boost_1_65_0/ berne@Bugg:~/tmp/boost_1_65_0$ ./bootstrap.sh --with-toolset=clang Building Boost.Build engine with toolset clang... tools/build/src/engine/bin.linuxx86_64/b2 Detecting Python version... 2.7 Detecting Python root... /usr Unicode/ICU support for Boost.Regex?... not found.
