For this last I don't think there is a good non-intrusive solution. If the default is to throw an exception then it effectively limits the contained type to those enumerated. In this case it is probably better to use variant in the first place. In Christ, Steven Watanabe

configure behavior is strange (writing to home dir)
by Neal Becker 12 Dec '06

12 Dec '06

I just grabbed RC_1_34_0. I ran configure and was surprised to see: Generating Boost.Build configuration in /home/nbecker/user-config.jam... That's not really expected behavior, to write to my home dir. Probably not really useful either if I build as a different user. Why don't we just write the the build dir?

This is typically independent of interpolation policy and would default to no smoothing.

I'll add an installation section to the docs. The library is header-only, so there is no lib to compile and link to. Boost.Time_series requires either Boost 1.34 or Boost CVS HEAD. If you already have a Boost installation with bjam, then just unpack time_series.zip into some empty directory, set a BOOST_ROOT environment variable to point at the root of your boost installation, and then you should be able to compile the example program (libs/time_series/example) with "bjam --v2" If you're a Visual C++ user, the example program has a .vcproj file, which will also get you going, so long as you set the BOOST_ROOT environment variable. If you're winging it, you just need to set the include directories like this: -I /home/eric/time_series/boost/backports \ -I /home/eric/time_series \ -I $BOOST_ROOT The backports include path must come before $BOOST_ROOT, and is only necessary if you are compiling against Boost 1.34. (It's not needed if you're compiling against HEAD.) HTH, -- Eric Niebler Boost Consulting www.boost-consulting.com

[python][iostreams][configure script] build/install issues
by David Abrahams 12 Dec '06

12 Dec '06

Issue 0: The configure script seems to not have been updated for BBv2. It is working OK by chance because the -sXXXX options it passes are just not relevant under BBv2. Doug, can you update it? Issue 1: My system didn't have bzlib.h and compilation was unceremoniously failing. Should the configure script detect this condition (and the lack of zlib) and set NO_BZIP2 and NO_ZLIB appropriately? Issue 2 (or maybe this is issue 0 again): I notice the configure script is detecting my PYTHON_ROOT and PYTHON_VERSION, but Boost.Build now handles that job itself (see the logic in tools/build/v2/tools/python.jam). Thanks, -- Dave Abrahams Boost Consulting www.boost-consulting.com

Boost inspection notification (2006-12-12/RC_1_34_0) *X*
by Rene Rivera 12 Dec '06

12 Dec '06

Boost Inspection Report Run Date: 17:04:06 UTC, Tuesday 12 December 2006 An inspection program <http://www.boost.org/tools/inspect/index.html> checks each file in the current Boost CVS for various problems, generating this as output. Problems detected include tabs in files, missing copyrights, broken URL's, and similar misdemeanors. Totals: 11423 files scanned 890 directories scanned (including root) 185 problems reported Problem counts: 0 files with invalid line endings 0 bookmarks with invalid characters 4 invalid urls 116 broken links 22 unlinked files 7 file/directory names issues 1 files with tabs 0 violations of the Boost min/max guidelines 35 usages of unnamed namespaces in headers (including .ipp files) Summary:

[type_traits][docs] example for is_base_of<> needs to be updated
by Pavel Kalugin 12 Dec '06

12 Dec '06

documentation for is_base_of says: "... Note that is_base_of<X,X> will always inherit from true_type..." and few lines after: "is_base_of<Base, Base>::value is an integral constant expression that evaluates to false: a class is not it's own base.", http://boost.org/doc/html/boost_typetraits/reference.html#boost_typetraits.… -- Pavel Kalugin

[configure] Running configure on dash.
by Daniel James 12 Dec '06

12 Dec '06

Hi, When I try running the configure script on Ubuntu I get: daniel@bah:~/src/boost$ ./configure --prefix=/usr/local/boost test: 180: ==: unexpected operator test: 193: ==: unexpected operator test: 213: ==: unexpected operator test: 218: ==: unexpected operator test: 222: ==: unexpected operator test: 226: ==: unexpected operator test: 243: ==: unexpected operator This is because Ubuntu now links /bin/sh to dash (the script works fine when called with bash). The bash man page says: string1 == string2 True if the strings are equal. = may be used in place of == for strict POSIX compliance. So I've attached a patch which uses '=' instead of '==' which seems to do the trick. Daniel
