Boost license and Open Source

Hi. I'm thinking of starting an open source project, and I'm seriously considering using Boost. I've read many messages regarding the practical aspects of using boost with other projects (particularly open source). However, I have found nothing useful regarding the legal aspect of using Boost for an open source project. As I'm considering licensing my project under the GPL, I'm concerned about the GPL "friendlyness" towards Boost. Besides the technical aspect of it, what is the best way to structure the project, to license the project, etc. in order to satisfy GPL and Boost licenses? Any help would be much appreciated. Best regards, Ezequiel "This communication is intended solely for the addressee and is confidential and not for third party unauthorised distribution."

CVS instructions at http://www.boost.org/more/getting_started.html#CVS don't work.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I tried to get a copy of Boost CVS using the instructions at http://www.boost.org/more/getting_started.html#CVS, but I got this error: ~ $ cvs -d:pserver:anonymous@cvs.boost.sourceforge.net:/cvsroot/boost login ~ Logging in to :pserver:anonymous@cvs.boost.sourceforge.net:2401/cvsroot/boost ~ CVS password: ~ cvs [login aborted]: connect to cvs.boost.sourceforge.net(66.35.250.209):2401 failed: Connection timed out However, when I use the SF CVS instructions at http://sourceforge.net/cvs/?group_id=7586, I have no problems. It recommends the following line instead. cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/boost login The difference seems to be cvs.boost.sourceforge.net versus cvs.sourceforge.net. Is this a temporary technical problem? Or should the instructions on the getting_started.html be updated? Thanks, Aaron W.

regex_search (v4) raises exception for wregex
by Adam Molnar 04 May '04

04 May '04

hi! the following pattern (35 matching token, and at least one more) with this simple expression ("[_]+$") throws "memory exhausted" when using wchar_t strings. the same works with char strings even triple sized. matching doesnt throw, if we use "^[_]+$", "[_]{1,}$", "[_][_]*$" etc. so this is a bug. it seems the expression-string is short enough to cause some problem, but i was unable to track down the error. wchar_t * wp = L"___________________________________x"; wregex wre(L"[_]+$"); try { regex_search(wp, wre); } catch (bad_expression & e) { cout << e.what() << endl; } another issue: i think, "(one|two|three|)" style alternation (notice the empty string on the right) should be accepted and handled as "(one|two|three)?" now it throws bad_expression

Problem 2 with Boost 1.31.0 Regex for tru64cxx65
by Richard Hadsell 04 May '04

04 May '04

Having persuaded everything to compile in the 1.31.0 Regex library, it runs into another problem in building the .a archive libraries: tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a /bin/sh: /bin/ar: arg list too long rm -f bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a ar r bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/c_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/c_regex_traits_common.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/cpp_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/cregex.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/fileiter.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/posix_api.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex_debug.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex_synch.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/w32_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/wide_posix_api.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/instances.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/winstances.o "bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release"/cxx_repository/* ...failed tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a... The problem is due to the number of instantiations in the template repository and the lengths of their names. There are 492 instantiations, and many of them have 90-character file names, which looks like the compiler's maximum allowed. I solved the problem in previous versions of boost by breaking up the build into separate steps. This was the way I modified the make file: AR:= ar -cq IIDIR:= $(LIBDIR)/cxx_repository $(DIRNAME)/lib$(LIBNAME).a : $(ALL_O) @echo "*** creating lib$(LIBNAME).a" rm -f $@ $(AR) $@ $^ @echo "*** adding template instantiations" $(AR) $@ $(IIDIR)/[_A-Z]* $(AR) $@ $(IIDIR)/[a-z]* It builds the library from just the object files and then adds the instantiations in two steps. (Apparently, adding all of them exceeded the same shell arg list limit.) How can I do something equivalent with bjam to build the library? -- Dick Hadsell 914-259-6320 Fax: 914-259-6499 Reply-to: hadsell(a)blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 44 South Broadway, White Plains, NY 10601

regex patches available
by John Maddock 04 May '04

04 May '04

All users of Boost.Regex-1.31.1 should be aware that there are now a set of patches available for this release - see https://sourceforge.net/project/showfiles.php?group_id=7586 for downloads. Issues fixed include: POSIX style regular expressions not behaving correctly with regex_grep. Non-greedy repeats not backtracking correctly in some cases. Backreferences cause some repeat operators to behave incorrectly. Some wide character expressions weren't getting correctly optimised, leading to thrown exceptions in trivial cases. Misc. compiler compatibility fixes. Regards, John Maddock

Problem building Boost 1.31.0 for VC6
by Estese 03 May '04

03 May '04

Hi, I'm trying to build the Boost 1.31.0 libraries for VC6 (on WinXP). My installation of MSVC is "C:\Program Files\Microsoft Visual Studio\VC98". All my user environment variables point to this location, as they should. I created the bjam executable, placed it in my Boost root (C:/boost_1_31_0), and then ran bjam with the following command: bjam "-sTools=msvc" However, it attempts to run the following command for every library: "CALL D:\Program Files\Microsoft Visual Studio .NET 2003\VC7\bin\cl" I don't even have .NET installed on my PC! Why would it be doing this? I tried explicitly telling bjam where vc6 is with the -sMSVC_ROOT argument, but it always outputs the same result. I've verified all my user environment variables, and they all point to C: and to VC6, as they should. I don't know why bjam insists on trying to build the boost libraries for Visual Studio .NET. Any thoughts? Sean Estey __________________________________ Do you Yahoo!? Win a $20,000 Career Makeover at Yahoo! HotJobs http://hotjobs.sweepstakes.yahoo.com/careermakeover

serialization library
by Russell Balest 02 May '04

02 May '04

Robert, Thank you for writing the serialization library. I'm in awe that someone finally did this so well. I've been using it for 2 days and think it's fantastic. I've been mucking with serialization frameworks myself for 8 years; now this will trump all my efforts and I'll give up and switch. Many Thanks, Russell Balest

lexical_cast<string> of type char
by DY, JERRY U (SBCSI) 01 May '04

01 May '04

I'm converting our code to use lexical_cast for converting between our numeric types to string. It worked mostly but was surprised to see what looked like graphic characters on my screen. It turns out that when we wanted to display the ascii value of a character, lexical_cast<string> doesn't work -- it doesn't treat the char as a numeric, which when we really think about it, makes a lot of sense. Casting the char to int solves the problem. But I was just wondering how the experts would handle this. char c = 65; string s1 = lexical_cast<string>(c) // s1 = "A" string s2 = lexical_cast<string>((int)c) // s2 = "65" Thanks! -Jerry
