Boost in Visual C++ 6.0
by imi123_1999 17 May '02

17 May '02

I am a newbie so please help me a little. I am using Visual C++ 6.0 in order to compile a program given as an example of threads. I am also copying the program below. But the problem is that the program is giving errors of unresolved externals. Please tell me how to change the settings of VC++ options. Here is the program: #include <boost/thread/thread.hpp> #include <iostream> int count = 0; boost::mutex mutex; void increment_count() { boost::mutex::lock lock(mutex); std::cout << "count = " << ++count << std::endl; } int main(int argc, char* argv[]) { boost::thread_group threads; for (int i = 0; i < 10; ++i) threads.create_thread(&increment_count); threads.join_all(); } The errors i am getting are: C:\Windows\Desktop\threadImI\imi.cpp(9) : error C2039: 'lock' : is not a member of 'mutex' c:\program files\microsoft visual studio\vc98 \include\boost\thread\mutex.hpp(35) : see declaration of 'mutex' C:\Windows\Desktop\threadImI\imi.cpp(9) : error C2065: 'lock' : undeclared identifier C:\Windows\Desktop\threadImI\imi.cpp(9) : error C2146: syntax error : missing ';' before identifier 'lock' C:\Windows\Desktop\threadImI\imi.cpp(19) : warning C4508: 'main' : function should return a value; 'void' return type assumed Error executing cl.exe.

RE: [Boost-Users] Boost threads compile with Sun WS6U2?

We use it with suncc and build it from a makefile. (We don't actually build any of the boost libs using Jam).

Call for Volunteers
by William E. Kempf 16 May '02

16 May '02

The Boost-install mail list is up and running (http://lists.boost.org/mailman/listinfo.cgi/boost-install to subscribe), and several people have subscribed. However, traffic is non-existent on the list. I'm concerned that the effort will die if we don't start some momentum. Currently, I have 4 people who volunteered to help with this effort. Hopefully these volunteers are just pressed for time right now and will start contributing shortly, but in any event we need more volunteers. So, I'm calling on people once again. The goal is to create a set of procedures for both the Boost developers and the Boost "installers" that will facilitate the creation of an installation "script" or set of "scripts" for supported platforms. The volunteers will help to define the procedures and to implement the "script(s)" for the target platforms so that Boost users can easily install Boost for use. We need volunteers with a lot of different qualifications. We need someone familiar with every supported platform (I don't mean that a single volunteer needs to know every platform) so that we can insure we define the procedures correctly and can provide an installation solution for every platform. We need people to help us document the procedures and to code the "script(s)". If you're interested in helping with this effort, please join the Boost-install list and let us know how you'd like to contribute. Thanks, Bill Kempf

Boost 1.28.0 released
by Beman Dawes 16 May '02

16 May '02

Boost release 1.28.0 is available. See the www.boost.org home page for news of what's in the release, how to download, and how to build. (Remember that only the Python, Regex, and Thread libraries currently require a build; the others are entirely implemented in the headers.) This is a major release, with both new libraries and lots of general improvements. Much effort has gone into smoothing out the build process for those who use the Python, Regex, and Thread libraries. Among other changes, the release .zip and .tar.gz files are being built via a new procedure, using CVS export. Please let me know right away if you have any problems with either file. --Beman

RE: [Boost-Users] unit testing framework for c++ in boost?
by bjorn.karlsson＠readsoft.com 16 May '02

16 May '02

Parts of this thread is becoming OT. It's fine to discuss libraries outside of Boost for comparison with their Boost equivalents, but the main topic must be about Boost. Bjorn Karlsson Moderator [Non-text portions of this message have been removed]

unit testing framework for c++ in boost?
by srivatsan raghavan 16 May '02

16 May '02

anyone know if there are plans to write a unit testing framework in boost? i've checked out unit++ , the interface doesn't seem very intuitive, and it seems rather feature limited and i kinda like CppUnit, but i get the feeling that since it's very similar to JUnit's interface, it's not as c++ friendly as it could be .. anyone know? __________________________________________________ Do You Yahoo!?

boost::shared_ptr and NULL
by Andrew R. Thomas-Cramer 14 May '02

In this function declaration, is there a simpler way to express a null shared pointer as the default argument value? void foo( const boost::shared_ptr<T> & p = boost::shared_ptr<T>( ) ); In this function call, is there a simpler way to express a null shared pointer as the actual argument? foo( boost::shared_ptr<T>( ) ); ----------------------------------------------------------------------- Andrew R.

Building regex - VC6 SP5 + stlport
by boolean_dream 14 May '02

14 May '02

Hey all, In the past I've had no problems building with this combo, but recently did a system reinstall and got the latest versions and am having trouble. Using: - Boost 1.27.0 - VC6 with SP5 - STLport 4.5.3 STLport is in the INCLUDE and LIB variables as instructed and to complie I just type nmake vc6-stlport.mak from libs\regex\build. After a lot of sutff compling fine I get the below error... I was actually able to fix it by adding in some ifdefs in regex.hpp, but that caused some other problems - clearly I'm doing something wrong. Any ideas? Many thanks. cl /nologo /MTd /W3 /Gm /EHa /Zi /Od /I..\..\..\ /DWIN32 /D_MT /D_DE BUG /D_MBCS /D_LIB /YX /FD /GZ /c -Fpvc6-stlport/vc6-stlport- re300dm/vc6-stlport- re300dm.pch -Fo./vc6-stlport/vc6-stlport-re300dm/ -Fdvc6-stlport/vc6- stlport-re3 00dm.pdb ../src/cregex.cpp cregex.cpp ..\..\..\boost/regex.hpp(402) : error C2011: 'regex_iterator_traits<char *>' : ' struct' type redefinition ..\..\..\boost/regex.hpp(404) : error C2011: 'regex_iterator_traits<char const * >' : 'struct' type redefinition ..\..\..\boost/regex.hpp(407) : error C2011: 'regex_iterator_traits<unsigned sho rt *>' : 'struct' type redefinition ..\..\..\boost/regex.hpp(409) : error C2011: 'regex_iterator_traits<unsigned sho rt const *>' : 'struct' type redefinition NMAKE : fatal error U1077: 'cl' : return code '0x2' Stop.

boost::shared_ptr<const T>
by Andrew R. Thomas-Cramer 13 May '02

13 May '02

Is it legal to construct a boost::shared_ptr<const T> from a raw T*? On MSVC6, it produces errors when class T has an implicit destructor, but compiles without error otherwise. ----------------------------------------------------------------------- Andrew R.

Re: building Boost using Jam
by jd.schmidt＠juno.com 13 May '02

13 May '02

OK, so I invoked Jam from my Boost root directory using: c:\boost_1_27_0\boost-build\jam -sBOOST_ROOT=. -sTOOLS="msvc" Now Jam is actually doing something, but I'm still getting messages like: The system cannot find the specified path. C:\Program is not recongnized as an internal or external command, operable program or batch file Also, I get a lot of messages like: ...found 1606 targets... ...updating 381 targets... [many other messages] ...failed msvc-C++-action [many other messages] ...failed updating 168 targets... ...skipped 202 targets... ...updated 11 targets... Obviously some things are happening, but I get the idea that it didn't work 100%.
