#########################################################################
# The boost threading library can be built on top of different API's
# Currently this is the win32 API and the pthreads API.
# Pthread is native on unix variants.
# To get pthread on windows you need the pthread win32 library
# http://sourceware.org/pthreads-win32 which is available under LGPL.
#
# You need to provide the include path and lib path in the variables
# PTW32_INCLUDE and PTW32_LIB respectively. You can specify these
# paths in site-config.jam, user-config.jam or in the environment.
# A new feature is provided to request a specific API:
# <threadapi>win32 and <threadapi>pthread.
#
# The naming of the resulting libraries is mostly the same for the
# variant native to the build platform, i.e.
# boost_thread and the boost specific tagging.
# For the library variant that is not native on the build platform
# an additional tag is applied:
# boost_thread_pthread for the pthread variant on windows, and
# boost_thread_win32 for the win32 variant (likely when built on cygwin).
#
# To request the pthread variant on windows, from boost root you would
# say e.g:
# bjam msvc-8.0 --with-thread install threadapi=pthread
