BLL for other compilers than GCC and Kai C++
by tslettebo1 19 May '02

19 May '02

Hi all. Have anybody got the Boost Lambda Library to work on other compilers than GCC and Kai C++ (which are mentioned in the documentation)? I have Intel C++ 6.0, which is quite standards compliant, but I get a zillion error messages, just by trying to compile boost/libs/lambda/test/bind_tests_simple.hpp. Trying it with MSVC 6.0 gives an ICE, but that's hardly unexpected. :) Also, are there any plans, on ongoing work, to make it more portable? (I post here, rather than the Boost list, as it's about use of a library) Regards, Terje

Boost threads compile with Sun WS6U2?
by NYSSEN Peter (BMB) 18 May '02

18 May '02

Hi all, I'm working on a multithreaded application on Sun Solaris 8 with Sun Workshop 6 update 2 installed. Currently my application uses the pthreads library. I've been looking at the Boost.threads library and I would like to use this instead of pthreads. I see that the Sun WS compiler is not in the supported toolsets list and there is no appropriate jam file available. In the Compiler Status: solaris page I see that this compiler is being tested, but no refference to the threads lib. Can anybody point me in the right direction as how I should build this lib in my environment? Is it enough if I try to create a jam file? Has anybody already done this (preferably for release 1_28)? What is the reason this compiler is not in the supported toolsets list?

Graph: Multiple edge properties with MSVC
by Siegel, Matthew 18 May '02

18 May '02

Hi, First off . . . great graph library. I can not get Visual C++ 6 SP5 to compile when I try to put multiple properties on the edges. Seems like a problem with the 3rd parameter that a boost::property can take another boost::property. When the 2nd property is taken out of the edge property list, everything works fine. Thanks for the help! Matt Example: // Vertex property - name as a string typedef boost::property<boost::vertex_name_t, std::string> VertexProperties; // Edge property - name as string, weight as a double typedef boost::property< boost::edge_weight_t, double, boost::property< boost::edge_name_t, std::string> > EdgeProperties; // Graph definition typedef boost::adjacency_list< boost::vecS, // Store out-edges in a std::vector boost::vecS, // Store vertex set in a std::vector boost::directedS, // Graph is directed VertexProperties, // Vertex properties EdgeProperties> Graph; // Edge properties Produces the following compiler error: Compiling... routetable.cpp c:\dev\lib\stlport-4.5.3\stlport\stl\char_traits.h(138) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information Error executing cl.exe. routing.exe - 1 error(s), 0 warning(s)

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.

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

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

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.
