Hi all, while developing some code for Boost, I've had to add some more tests to the configuration headers so that BOOST_NO_STDC_NAMESPACE gets defined when some functions cannot be found (e.g., std::strdup, which is missing under NetBSD). This is irrelevant, because this symbol could get defined in a future by other changes in Boost. The problem is that when BOOST_NO_STDC_NAMESPACE is defined under NetBSD, Boost.Iostreams does not work any more and breaks the build of programs using it. Consider the following code example: ----- #define BOOST_NO_STDC_NAMESPACE #include <boost/iostreams/device/file_descriptor.hpp> int main(void) { return 0; } ----- When building it, I get: ----- $ g++ -I/home/jmmv/opt/include test.cc In file included from /home/jmmv/opt/include/boost/iostreams/positioning.hpp:19, from /home/jmmv/opt/include/boost/iostreams/device/file_descriptor.hpp:24, from test.cc:2: /home/jmmv/opt/include/boost/iostreams/detail/config/codecvt.hpp:70: error: ` codecvt' not declared ----- The problem arises because codecvt does not exist in the global namespace under NetBSD, although it does inside std::. Therefore, the 'using ::codecvt' line (the one that triggers the error) breaks the build. I don't know how this should be fixed, so I'm just sending a bug report. Maybe the BOOST_NO_STDC_NAMESPACE definition should be made more fine grained, so that defining it due to the lack of a function does not affect others that may exist? Should I file a bug report or is this message enough? Thanks, -- Julio M. Merino Vidal <jmmv84@gmail.com> http://www.livejournal.com/users/jmmv/ The NetBSD Project - http://www.NetBSD.org/
