Can I use read_graphviz to initialize a graph from a *.dot file where properties are stored as bundled properties as opposed to property maps? -- William Yun Chen '09 Hinman Box 1826 Dartmouth College Hanover, NH, 03755

[serialization] Announcing eos portable archive
by Pfligersdorffer, Christian 26 Sep '08

26 Sep '08

Dear boost fellows, during the last two weeks I finally had time to port our archives to recent boost versions up to 1.36. I also refactored a bit, put the archives into namespace eos and renamed them portable_[io]archive in order to prevent further mix-up with the portable binary archive from the examples. In addition I finally did some testing on x64 and found our code working without complaints. So I encourage anyone who wants to use binary serialization across different platforms with floating point support to have a look at it at the boost vault: http://www.boostpro.com/vault/index.php?directory=serialization Cheers, -- Christian Pfligersdorffer Software Engineering http://www.eos.info

Boost Interprocess: Sharing memory among different users
by Silvio Reis Junior 26 Sep '08

26 Sep '08

Hello folks!I'm writing a software for the Linux environment. I'll need to share data between a daemon and a program running on the user's context. I chose to use shared memory because it's faster. I'm trying to use boost::interprocess::shared_memory_object but I'm facing a problem: When I access the shared memory in my test case running in the same user context, everything works fine. But when I access it using a program running in the current user when the shared memory was created as root, I get an access denied error. I searched in the documentation for a way to enable access to all users but I found nothing. Is there a way to do it? Thanks in advance. Silvio.

boost::asio::write() never returns
by Jean-Sebastien Stoezel 26 Sep '08

26 Sep '08

Hi, I use the Boost ASIO library to send TCP packets of about 500k every minute to a TCP server. I run my application on Windows XP, the server runs on a UNIX station. I use boost 1.35 While this works well initially, eventually after 4 or 5h the call to boost::asio::write() never returns, and locks my thread. No exception is generated. I checked the RAM resources on my computer when this happens and it looks like it's stable (I don't think there is any memory leak). If I were to speculaate on this, I woudl say it looks like the call suddently becomes blocking for some reason. this being either a TCP stack being full, or no answer from the server... Any help will be greatly appreciated. Thanks! Jean

Hi there I am looking for a logging library, and has gotten confused about wheter: http://www.torjo.com/log2/ or http://boost-log.sourceforge.net/libs/log/doc/html/index.html is most likely to gain acceptance within the boost community? Any thoughts?

Change from binary_oarchive to text_oarchive gives 'sizeof' compilation errors
by James Vanns 26 Sep '08

26 Sep '08

Hi, in trying to debug a problem we are experiencing here with binary archives I tried switching to text archives to see if we get the same behaviour. However, now I can't even compile my code! A straight swap for binary_oarchive to text_oarchive gives me these errors: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ The arrangement of my header files is like so: // base_msg.h #include <boost/archive/tmpdir.hpp> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> using boost::archive::text_oarchive; using boost::archive::text_iarchive; class Base { private: text_oarchive out; text_iarchive in; }; template<class T> class MsgSerializer : public T, public Base { ... }; // msg.h #include "base_msg.h" // Boost containers, algorithms etc. #include <boost/serialization/map.hpp> #include <boost/serialization/string.hpp> #include <boost/serialization/vector.hpp> #include <boost/serialization/base_object.hpp> #include <boost/serialization/split_member.hpp> struct MyMsg_ { template<class Archive> void serialize(Archive &p_archiver, const unsigned int /* version */) { } }; typedef MsgSerializer<MyMsg_> MyMsg; etc. I have literally just changed binary_ for text_ and it now spits out said error whenever it encounters MyMsg_. This used to compile fine. Even if I re-arrange the headers I still get the same error? What must I change to get text_archives to compile!? I've also tried adding access.hpp (which I didn't have to do before) and serialization.hpp all to no avail. Regards, Jim -- James Vanns Systems Programmer Framestore CFC Ltd.

[python] Defining a variable
by Robert Dailey 25 Sep '08

25 Sep '08

Hi, I'm embedding python through Boost.Python. Before I "import" or "exec" a specific PY file, I want to set a global variable in that script that the user will be able to access when the script is finally executed or imported. How would I do this?
