regex and std::towlower
by Tim Clemons 11 Sep '04

11 Sep '04

I'm attempting to compile against the boost_regex headers on Solaris 2.8, using gcc and STLport. I'm encountering the following compile error: /boost/boost/regex/v4/regex_traits.hpp: In static member function `static boost::regex_wchar_type boost::c_regex_traits<boost::regex_wchar_type>::translate(boost::regex_wchar_type, bool)': /export/build/pixie/aegis-build/dev/liberty/common/cpp/utils/boost/boost/regex/v4/regex_traits.hpp:290: error: `towlower' is not a member of `_STL' Any ideas? This appears to be specific to Solaris, as the code base compiles alright on Linux. Appreciate the help. -- Tim.

LNK1104: cannot open file 'libboost_unit_test_framework-vc71-sgd.lib'
by Roy Varghese 11 Sep '04

11 Sep '04

Hi I am trying to build a test program that comes with the Genserial library (http://genserial.soureforge.net) which uses boost. I get the following error while linking: test fatal error LNK1104: cannot open file 'libboost_unit_test_framework-vc71-sgd.lib' This library seems to be included because of these lines in one of the cpp files: #include <boost/test/unit_test.hpp> using boost::unit_test_framework::test_suite; I verified that the file does exist in boost\lib however the naming is different, it has a version number suffix to it "libboost_unit_test_framework-vc71-sgd-1_31.lib'" hence the problem with the linker. How do I go about resolving this, short of renaming all the lib files? Thanks Roy --><8---Profound quote snipped by email server--><8---.

Boost.Build Main vs. exe
by Steven T. Hatton 10 Sep '04

10 Sep '04

There seem to be two different general approaches to using bjam. One is to use "objects" such as /Main/ and /Library/. This is described here: http://www.boost.org/tools/build/jam_src/Jamfile.html The other approach is to use "rules" such as /exe/ and /lib/. This is described here: http://www.boost.org/tools/build/v1/build_system.htm Am I correct in viewing these as separate approaches that I am free to choose between? Is one approach preferable to the other in terms of future compatability, or generally accepted practices? -- Regards, Steven

High level question on iterator_adaptor vs iterator_facade
by Brian Braatz 10 Sep '04

10 Sep '04

I have worked through the tutorial on iterator_facade. (extremely cool library)- and I am reading about iterator_adapter- but what I am not seeing is the high level picture here. My Question: In a nutshell- what is the basic difference between iterator_adapter and iterator_facade? When would I use one over the other? Any thoughts appreciated thanks Brian

Newbie Q
by Jon Handler 10 Sep '04

10 Sep '04

Hi, I'm failing to build either bjam or (eventually, I got the binary) the boost library. I'm using Win 2K, VC++ 6, boost 1.31.0. In setting environment variables, I set MSVC, but couldn't figure out VISUALC (since I don't have a VC++ directory). When I try to build, I get: D:\boost_1_31_0>bjam "-sTOOLS=msvc" install [ Fails to find PYTHON ] ...patience... ...found 7592 targets... ...updating 3079 targets... MkDir1 C:\Boost spawn: No such file or directory Thanks, Jon

boost lib naming conventions on OSX (darwin)
by Simmons, Aaron 10 Sep '04

10 Sep '04

I have built and installed boost on Mac OSX (using the 'darwin' toolset). I've noticed that the libboost libraries that are built don't follow the boost naming conventions. Specifically, they don't include the 'osx' toolset identifier as specified in the 'Getting Started' documentation at http://boost.org/more/getting_started.html#Results Is this a known issue? Thanks, Aaron Simmons

Building Boost on Mac OS X
by John Meinel 10 Sep '04

10 Sep '04

I've been trying to build boost-1_31_0 on Mac OSX (10.3.5). I first tried with the default compiler, and then I installed XCode 1.5 to get gcc build 1666, which seems to be what is listed on the main site. After all this, the problem I get is: c++ unrecognized option `-shared' As near as I can tell, it builds everything except for the shared libraries. I would really prefer to use the shared libraries, though if I can get my program to compile against the static it probably would be okay. Does anywone know of a workaround? I read something online that said "try using -G instead of -shared", but that just gave me -G as an unrecognized option. I'm trying to build CVS right now, but I don't know how stable/etc it is. I would much rather use a release, because if I download it later, I know it will still be the same code. Any pointers would be appreciated. John =:->

RE: [Boost-users] Help with Path Constructor
by John Wilkinson 09 Sep '04

Is this a Unicode build? I'm assuming not, since you don't cast the result of GetBuffer, but your code will not work properly with Unicode. In any case, you don't need to use GetBuffer to get a pointer (const TCHAR *) to the buffer; just cast to LPCTSTR (which works for either Unicode or multibyte). It also might help to know what version of Visual Studio you're using.

autoconf m4 macro for boost
by Rodolfo Schulz de Lima 09 Sep '04

09 Sep '04

(answering the mail from Thomas Lemaire) I've attached to this mail the .m4 macros that I made to configure boost automatically in my autoconf/automake projects. It's not complete, nor optimal, but suit my needs. Put it in your /usr/share/aclocal directory and in your configure.ac put: RS_BOOST([1.32.0],[],[AC_MSG_ERROR([Package requires the Boost C++ libraries!])]) RS_BOOST_REGEX RS_BOOST_THREAD RS_BOOST_DATE_TIME RS_BOOST_PROGRAM_OPTIONS it'll create acsubst'ed BOOST_CPPFLAGS, BOOST_LIBS and BOOST_LIBS_R Since I use it to compile for ming32 (win32) and gcc (linux) targets, it's good to have AC_CANONICAL_TARGET right before AM_INIT_AUTOMAKE if you want the m4 to choose between mgw and gcc libraries according to the target you're building for. And if you define something like AC_ARG_ENABLE(debug,....), thus defining enable_debug variable, the m4 will select the debug/release libraries whether enable_debug is yes or no. Then you should put AM_CPPFLAGS=@BOOST_CPPFLAGS@, LIBS=@BOOST_LIBS@ (or @BOOST_LIBS_R@ if you want the recurrent (thread-safe) version of the libraries) somewhere in a Makefile.am That's it... I hope it'll be as useful to you as it is being to me. Regards, rod

Look in Project/<project name> Properties. In the resulting dialog, pick General under Configuration Properties. In the listbox on the right, look at "Character Set", which will tell you whether or not you are using Unicode. I think that Visual Studio defaults to Unicode builds these days, so you should really check this to make sure. A binary dump of the contents of temp2 after the GetWindowText call might be helpful (binary dump so that we can tell if it's Unicode or not). Try this block of code in place of your original: //m_scanPath is a control variable for the textbox containing the directory. CString temp2; //Since the stuff in the textbox is a CString. m_scanPath.GetWindowText(temp2); //Get the directory entered in the textbox. fs::path scanPath((LPCTSTR) temp2); //This does not work even though the param is a const char *) Let me know if it compiles, and what happens when you run it.
