# Defines settings for building the TBB run-time as a static library.
# Use these only on platforms where dynamic linking is impractical.
#
# IF YOU USE TBB AS A STATIC LIBRARY, YOU MUST GUARANTEE THAT ONLY ONE COPY OF 
# THE TBB RUN-TIME IS LINKED INTO AN APPLICATION!  LINKING IN MULTIPLE COPIES
# OF THE TBB RUN-TIME, DIRECTLY OR INDIRECTLY, MAY CAUSE PROGRAM FAILURE!

# Note that ITT_NOTIFY allows to selectively remove the definition of
# DO_ITT_NOTIFY without sabotaging deferred expansion of CPLUS_FLAGS.
# TODO: currently only in linux.{gcc,xl}.inc

# Note that -pthread with xl gives "1501-210 (W) command option t contains an incorrect subargument";
# multithreading is instead achieved by using the _r affix in the compiler name.
# TODO: is -lpthread still relevant/needed with XL and _r affix?

# Note that usage of dynamic (shared) libraries is disabled
# (via -D__TBB_DYNAMIC_LOAD_ENABLED=0 and LIBDL emptied) primarily for performance.
