[Q] Boost-Build V2
by Chris Drexler 18 Aug '03

18 Aug '03

Dear Listmembers, since a few weeks I'm using boost within a development system which should be changed towards operating system independence. As boost-buil V2 has a lot of nice features I wanted to base the build process on it. Unfortunatly it's very confusing to get all the information I need and sometimes it is not clear to which boost-build version (v1 or v2) some documentation belongs to. I hope this list is the right place to ask some questions about this. I'm going to describe the my current setup first (which is a little bit longish in order to cover all important points, hopefully) and afterwards I'll explain the problems. The scenario: We have some self-made class libraries which depend on downloaded packages (one is boost). So I thought of using the (usage-)dependency features of boost-build v2 for automatically using the right include paths and the according libraries. (I'm using milestone 6 of boost-build) root | + pkgs + boost_1_30_0 | | | + log4cpp_0.3.4b + include | + lib | + mylib + include | + src | + myapps + testapp + src The idea was to separate the information of which package versions to use and where libraries and include files reside. For this I put a Jamfile into 'pkgs' which consist of the following entries (OS independence not included right now) ------------------------------------------------------------------- project pkgs ; BOOST = boost_1_30_0 ; LOG4CPP = log4cpp-0.3.4b ; # system libraries lib winsock : : <name>Ws2_32.lib ; lib advapi : : <name>Advapi32.lib ; alias all : log4cpp boost ; alias boost : : <include>$(BOOST) ; lib log4cpp : : <file>$(LOG4CPP)/msvc6/log4cpp/Release/log4cpp.lib <variant>release : : <library>winsock <library>advapi ; lib log4cpp : : <file>$(LOG4CPP)/msvc6/log4cpp/Debug/log4cpp.lib <variant>debug : : <library>winsock <library>advapi ; ------------------------------------------------------------------- and the Jamfile in 'root' (where project-root.jam and boost-build.jam resides) contains ------------------------------------------------------------------- project MyProject : default-build debug <link>static ; use-project /pkgs : ./pkgs ; use-project /MyLib: ./mylib ; ------------------------------------------------------------------- The Jamfile in 'mylib' uses several of the libraries defined in 'pkgs' ------------------------------------------------------------------- project MyLib : usage-requirements <include>./include : requirements <include>./include : source-location ./src ; LIBSRC = [ .. whatever ..] ; lib MyLib : $(LIBSRC) : : : <library>/pkgs//log4cpp ; lib MyLib2 : $(LIBSRC) : : : <library>/pkgs//all ; ------------------------------------------------------------------- and the application 'testapp' depends on 'mylib' ------------------------------------------------------------------- project testapp : requirements <library>/MyLib//MyLib : source-location ./src ; exe test : testapp.cpp ; exe test2 : testapp.cpp : : <library>/MyLib//MyLib2 ; ------------------------------------------------------------------- Problems/Questions ================== - I had to put a (empty) 'project-root.jam' file into 'pkgs'. Otherwise I get the error message: error: default build can be specified only in first alternative main target is ../../../pkgs/log4cpp Any ideas why this happens? - the library dependcies for 'log4cpp' are correct and the appropriate library is linked BUT the include depencies are not used (neither for boost nor for log4cpp). I had to add the paths once more into the Jamfile in 'root' to make them available. After the changes the Jamfile looks like this ------------------------------------------------------------------- BOOST = pkgs/boost_1_30_0 ; LOG4CPP = pkgs/log4cpp-0.3.4b ; project MyProject : default-build debug <link>static : requirements <include>$(BOOST) <include>$(LOG4CPP)/include ; use-project /pkgs : ./pkgs ; use-project /MyLib: ./mylib ; ------------------------------------------------------------------- This is not what I wanted because now the paths to the package directies appear twice, once in root/Jamfile and once in root/pkgs/Jamfile. Thanks you very much ! Best Regards, Chris Drexler

RE: [Boost-Users] [date_time] library binaries for VC7.1? && Comm on lib placement
by Administrator 18 Aug '03

18 Aug '03

Dan, The date_time.lib library is a static lib. The built date_time.dll actually has no exports in it, so for VC purposes is useless. I would say don't worry about it, and just use the static lib. On a side note, has anyone been working on placing built items into a common directory, say <boost_top_dir>/lib? If not, I have a patch that should help alot.

Type Traits
by Hossein Haeri 18 Aug '03

18 Aug '03

Hi friends, I'm looking for some stuff like the Loki::TypeTraits. I presume that there should be some similar ones in the boost repository. If I'm right, please tell me where they are. Thanks, --Hossein __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com

uClibc and Boost
by codeazure 18 Aug '03

18 Aug '03

Has anyone had success using Boost with the uClibc libraries? In particular, have you got Boost.Python to work? I am using the getting_started1.cpp example provided with Boost. I am using Boost 1.30.0, uClibc 0.9.20 and Python 2.2.3. Note that uClibc does not currently support a dlopen() called library calling a dlopen(). I have found that as long as the library is loaded with Python, I can get it to work. I am currently using the SSL version of the socket module, which is using SSL libraries linked against Python. I have tried 2 techniques so far, but both result in core dumps. 1. Compile Python against uClibc and force linking with libboost_python.so 2. Compile Pyhton against uClibc only. Build Boost application by linking against libboost_python.a so no external library is needed. It may be that the 2 libraries are simply not compatible at this stage. Does anyone have any ideas? David Abrahams has suggested low level debugging to work out what is causing the core dump, but if the problem lies deep within uClibc, then I have a problem. Regards, Jeff Gray

Variant library or alternative suggestion
by vivek_arora 17 Aug '03

Whats is the status of the variant library which was supposed to have been approved for inclusion? I was unable to compile the code submitted for review. Are there any alternative ways/libraries for representing typesafe unions ? thanks -Vivek Arora

newbie metaprogramming question
by Istvan Buki 17 Aug '03

17 Aug '03

Hello Boost experts, I'm starting learning about template metaprogramming and I discovered that Boost provide several libraries in that area. I tried to see if those libraries could be used for a piece of code I have in my mind but I have a hard time figuring out how to start with it. I don't know if it is because I try to apply metaprogramming techniques in a use case where they doesn't fit or because of my lack of experience with these tools. I'm posting my use case here to get some help and advice about it. In a library I provide two classes: 1) An abstract base class (let's call it Base) from which user will derive their own classes. 2) A manager class responsible for manipulating instances of classes derived from Base. The user, in his application, create an an arbitrary number of classes derived from Base. Let's call them A, B and C for example. He create a typelist containing all those classes and passes it as a parameter to the manager class: typedef boost::mpl::list< A, B, C > my_types ; typedef Manager< my_types> my_manager ; When an instance of my_manager is created I would like to automatically create one instance of each type present in the typelist and these instances should be stored in a container where I could access them later. Something like the following: template < class Typelist > class Manager { public: Manager( void ) ; // ..... private: std::vector< Base * > container_ ; // .... } ; template < class Typelist > Manager< Typelist >::Manager( void ) { // This is not C++, it is pseudo-code that shows what I would // like to achieve. FOR EACH Typelist item i DO Base *b = new Typelist[i] container_.push_back( b ) ; END } So, at compile-time, some code should be generated to do what I wrote in pseudo-code in the constructor of Manager. Does this make any sense ? And if it is, could someone help me transform transform the pseudo-code in the constructor of manager to real code ? Thanks for any help you could provide, Istvan

Errors building boost w/ VC++ 6.0 sp5
by Michael H. Cox 17 Aug '03

I downloaded boost_1_30_0.zip, unpacked the zip file, cd'ed into boost_1_30_0, and ran "bjam "-sTOOLS=msvc". Most of the library seemd to compile fine (Python was skipped since I didn't have it installed). Bjam failed to update 12 targets, skipped 12 targets (the same 12 that failed?), and updated 452 targets.

Hello, I am newbie to boost.python. Currently, I have a projects to wrap our c++ code to python module using boost_python. I download boost_1_19_0 and built it in .net, now I want to test the libraries is right or not, I try to build the hello module in the example, but fail, it saying that: c:\Program Files\Microsoft Visual Studio .NET\Vc7\include\cstdio (15): error C2059: syntax error : ':' any trick about it
