Compilation problem with date_time and iostream gzip (and bzip2) filters
This simple test fails to compile with gcc 4.0.1 (or 4.0.2, it's the debian unstable version) and boost 1.33.0 if the date_time include is uncommented. Is there any known incompatibility between the two libraries ? #include <boost/iostreams/filtering_stream.hpp> #include <boost/iostreams/filter/gzip.hpp> // #include <boost/date_time/local_time/local_time.hpp> int main() { boost::iostreams::filtering_istream in; in.push(boost::iostreams::gzip_compressor()); return 0; } The full error is attached /usr/include/boost/iostreams/filter/symmetric.hpp: In member function ‘std::streamsize boost::iostreams::symmetric_filter<SymmetricFilter, Alloc>::read(Source&, typename boost::iostreams::char_type_of<T>::type*, std::streamsize) [with Source = boost::iostreams::detail::linked_streambuf<char, std::char_traits<char> >, SymmetricFilter = boost::iostreams::detail::zlib_compressor_impl<std::allocator<char> >, Alloc = std::allocator<char>]’: /usr/include/boost/iostreams/filter/gzip.hpp:199: instantiated from ‘std::streamsize boost::iostreams::basic_gzip_compressor<Alloc>::read(Source&, char*, std::streamsize) [with Source = boost::iostreams::detail::linked_streambuf<char, std::char_traits<char> >, Alloc = std::allocator<char>]’ /usr/include/boost/iostreams/read.hpp:215: instantiated from ‘static std::streamsize boost::iostreams::detail::read_filter_impl<boost::iostreams::multichar_tag>::read(T&, Source&, typename boost::iostreams::char_type_of<T>::type*, std::streamsize) [with T = boost::iostreams::basic_gzip_compressor<std::allocator<char> >, Source = boost::iostreams::detail::linked_streambuf<char, std::char_traits<char> >]’ /usr/include/boost/iostreams/read.hpp:56: instantiated from ‘std::streamsize boost::iostreams::read(T&, Source&, typename boost::iostreams::char_type_of<T>::type*, std::streamsize) [with T = boost::iostreams::basic_gzip_compressor<std::allocator<char> >, Source = boost::iostreams::detail::linked_streambuf<char, std::char_traits<char> >]’ /usr/include/boost/iostreams/detail/adapter/concept_adapter.hpp:247: instantiated from ‘static std::streamsize boost::iostreams::detail::flt_wrapper_impl<boost::iostreams::input>::read(Filter&, Source*, typename boost::iostreams::char_type_of<T>::type*, std::streamsize) [with Filter = boost::iostreams::basic_gzip_compressor<std::allocator<char> >, Source = boost::iostreams::detail::linked_streambuf<char, std::char_traits<char> >]’ /usr/include/boost/iostreams/detail/adapter/concept_adapter.hpp:74: instantiated from ‘std::streamsize boost::iostreams::detail::concept_adapter<T>::read(typename boost::iostreams::char_type_of<T>::type*, std::streamsize, Source*) [with Source = boost::iostreams::detail::linked_streambuf<char, std::char_traits<char> >, T = boost::iostreams::basic_gzip_compressor<std::allocator<char> >]’ /usr/include/boost/iostreams/detail/streambuf/indirect_streambuf.hpp:250: instantiated from ‘typename boost::iostreams::detail::indirect_streambuf<T, Tr, Alloc, Mode>::int_type boost::iostreams::detail::indirect_streambuf<T, Tr, Alloc, Mode>::underflow() [with T = boost::iostreams::basic_gzip_compressor<std::allocator<char> >, Tr = std::char_traits<char>, Alloc = std::allocator<char>, Mode = boost::iostreams::input]’ test.cpp:10: instantiated from here /usr/include/boost/iostreams/filter/symmetric.hpp:112: error: ‘boost::iostreams::symmetric_filter<boost::iostreams::detail::zlib_compressor_impl<std::allocator<char> >, std::allocator<char> >::<anonymous enum>’ is/uses anonymous type /usr/include/boost/iostreams/filter/symmetric.hpp:112: error: trying to instantiate ‘template<class T> struct boost::is_integral’ /usr/include/boost/iostreams/filter/symmetric.hpp:124: error: ‘boost::iostreams::symmetric_filter<boost::iostreams::detail::zlib_compressor_impl<std::allocator<char> >, std::allocator<char> >::<anonymous enum>’ is/uses anonymous type /usr/include/boost/iostreams/filter/symmetric.hpp:124: error: trying to instantiate ‘template<class T> struct boost::is_integral’ /usr/include/boost/iostreams/filter/symmetric.hpp:131: error: ‘boost::iostreams::symmetric_filter<boost::iostreams::detail::zlib_compressor_impl<std::allocator<char> >, std::allocator<char> >::<anonymous enum>’ is/uses anonymous type /usr/include/boost/iostreams/filter/symmetric.hpp:131: error: trying to instantiate ‘template<class T> struct boost::is_integral’

This appears to be the GCC 4.0 + SFINAE + anonymous enum problem discussed in this thread: http://lists.boost.org/Archives/boost/2005/08/91958.php. I'd guess that Date_Time is using anonymous enum (directly or indirectly) and it's interfering with a SFINAE'd operator in Iostreams, or vice versa. Even if I can fix the interaction between Date_Time and Iostreams, it may still be a problem when one of the two libraries is used with certain non-Boost libraries. I'll work on fixing it. In the mean time, it would be helpful if you could name the several anonymous enums defined in Iostreams and report back. E.g., at line 148 of boost/iostreams/filter/aggregate.hpp, change enum { to enum flag_type { (you can use the name "flag_type" everywhere.) The affected files seem to be boost/iostreams/filter/aggregate.hpp boost/iostreams/filter/gzip.hpp boost/iostreams/filter/line.hpp boost/iostreams/filter/symmetric.hpp Jonathan

OK. I've seen that this was a problem with anonymous enums, but I haven't found the exact reason.

There is more files with anonymous enums in iostream. a quick grep gives this: $ rgrep "enum {" boost/iostreams/* boost/iostreams/code_converter.hpp: enum { boost/iostreams/detail/streambuf/indirect_streambuf.hpp: enum { boost/iostreams/filter/line.hpp: enum { boost/iostreams/filter/symmetric.hpp: enum { boost/iostreams/filter/gzip.hpp: enum { boost/iostreams/filter/gzip.hpp: enum { boost/iostreams/filter/aggregate.hpp: enum { I changed them, and the example in my first post compiles, with both gzip and bzip2 filters. Patch attached. Thanks for the quick response

Great! Thanks for the patch. The fix will appear in 1.33.1

Been looking at this one for a bit, and thought I would post to see if anyone else has has this problem. BASIC INFO: I am running OS X 10.4.2 I have Bjam successfully configured to build boost and run the regression tests (YEAH!) In user-config.jam, I have set my tools=darwin as opposed to gcc (gcc does NOT work on Mac OS with boost due to the "zerolink" functionality apple added to GCC) I have been searching google and so far have found other people with a simliar problem, most notably when porting BSD apps to OSX. (but as of yet no solution) As it sits right now, I am trying to get the documentation to build with BJAM, but running the jamfile in \boost_root\docs is failing on a build of Quickbook. Below is the details of the attempted BJAM of quickbook directly. Any thoughts or help appreciated. Thanks, Brian DETAILS: $ bjam --v2 warning: Python location is not configured warning: the Boost.Python library won't be built Building Boost.Regex with the optional Unicode/ICU support disabled.

More info- I took the link command (from below error) copy- pasted- and removed the -static (per an usenet posting I saw with a similar fix) DOING THIS, allowed quickbook to build a DEBUG but not a release. There appears to be a bjam\config BUG with the quickbook jam file using the darwin toolset. I then used my user-config.jam to give it an explict path to the quickbook binary. So far so good, for me at least. It looks like the docs are now building. BUT- this leaves open the problem of this not working on OSX. I am *not* an expert on BJAM, but I am more than willing to try out things and debug this for the benefit of fixing this bug. If anyone (who is smarter about BJAM than me) who would like to help fix this bug. You are welcome to send mail on this list or send mail to me privately.

This thread discusses vc7.1 -- not sure I see the connection unless you are saying gcc 4 has the same problem?

It's indirect... Jeff

Gcc does have the problem; the title of the thread is misleading. See later posts such as: <http://lists.boost.org/Archives/boost/2005/08/92002.php> and <http://lists.boost.org/Archives/boost/2005/08/92004.php> For now it is SFINAE cannot be safely, portably used upon anonymous enums, though this could change, depending how we resolve core issue 488. - Mat
