[serialization] linking issues with 1.33
by rwm33＠drexel.edu 15 Feb '06

15 Feb '06

Hello When updating libraries from boost 1.32 to 1.33 our previous code that had no previous linking problems developed linking errors. I then attempted to compile the demo.cpp serialization code included in the boost documentation tutorial and received the same errors. I attach below the code and the error message I got. I am working on a Linux Gentoo machine with Boost installed by e-portage. I believe boost is properly installed as it works with other libraries. Any suggestion?

AIX/g++

Hi, I don't see any AIX regressions so I'm assuming no one officially tests this. Does anyone have any notes about this platform/compiler combination? Does it work? :) Thanks in advance, Sohail

Tricky RPC code using bind()
by Sean Rhea 14 Feb '06

14 Feb '06

All, I've written what I thought was a pretty clever RPC server using bind and templated functions to make server callbacks typesafe. It all resolves around this one function: class rpc_server { ... template <class A, class R> void set_handler(int prog, int vers, int proc, bool_t (*arg_fn)(XDR *, A*), bool_t (*res_fn)(XDR *, R*), function<void(A*,function<void(R*)>)> req_cb) { … [View More]

iostreams library and zlib/bzip2 support
by Robert Vinluan 14 Feb '06

14 Feb '06

Hi All, Right now, in order to compile and link to the iostreams library with zlib/bzip2 support, I have to include the .cpp files in my project (as mentioned in the boost docs). I'm not too fond of this idea as I want to keep 3rd-party code outside of my project build. Perhaps I have missed something in the docs, but is there another way to link with the iostreams library without including the .cpp files? Also along these lines ... is there any reason why zlib.cpp and bzip2.cpp are … [View More]

Solved my problem, RE: program_options wide chars.
by John Gardner 14 Feb '06

14 Feb '06

Apparently the library is compiled treating wchar_t as a built-in type. This applies to at least Visual Studio .Net 2003, and probably 2005. Programs that link with the program_options lib need to define /Zc:wchar_t, e.g. Project Properties -> C/C++ -> Language -> Treat wchar_t as Built-in Type -> Yes --John Gardner

Tree data structure

Which of the boost libraries do I need for creating a tree data structure? Purpose is to hold data for a legend for a map. The legend has different layers and each layer may have sublayers. Thanks, Jeroen Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
