Subject: [Boost-users] [wave] Tracing a macro in a preprocessor directive
From: Edward Diener (eldiener_at_[hidden])

I was trying to trace the output of a macro within a preprocessor
directive in a file using the Wave trace facility. The directive is:
#elif BOOST_PP_ITERATION_FLAGS() == 1
so I specified:
#pragma wave trace(enable)
#elif BOOST_PP_ITERATION_FLAGS() == 1
#pragma wave trace(disable)
But wave's trace showed me an empty file where the macro output (
-tsomefile ) should have been.
Is there a way to capture the output of the BOOST_PP_ITERATION_FLAGS()
macro at the point where the #elif is occuring using Wave's trace facility ?
