13460	broken shared build.	pawels@…	Vladimir Prus	"hi,

i'm using a boost with a custom namespace (e.g. bcp --namespace='''foobar''' --namespace-alias ...). for such configuration the current version of program_options doesn't export symbols from shared library.

afaics the current boost build system defines in such configuration -D'''FOOBAR'''_PROGRAM_OPTIONS_DYN_LINK=1 macro which doesn't match the boost/program_options/config.hpp:37 #ifdef:

#if defined(BOOST_ALL_DYN_LINK) || defined('''BOOST'''_PROGRAM_OPTIONS_DYN_LINK)

finally, the BOOST_PROGRAM_OPTIONS_DECL macro is empty.

this is a regression from boost-1.64.0."	Bugs	new	To Be Determined	program_options	Boost 1.66.0	Regression
