Reposting this here since I got no response on "users" but this list seems more appropriate:

Using boost 1.55, Ubuntu 12.04, gcc 4.6

I'm building boost on linux using the lsb sdk (4.1.8) . I was getting the failure (paraphrased):

pthread_yield not declared

in libs/thread/src/thread.cpp 513

The documentation for pthread_yield ( says:

This call is nonstandard, but present on several other systems. Use the standardized sched_yield(2)<> instead.

If I change boost/config/platform/linux.hpp to define


instead of


Then sched_yield is used instead and the build finishes properly.

I'm posting this for two reasons:

  1. To help others running into the same issue
  2. To question whether linux.hpp should be updated officially as I did above
  3. If not, why
