I have tried to follow your advice but I have encountered a little problem, and I can't find the solution on documentation. When I tried to install bgl-python-0.9 (boost.graph bindigs) I retrieved this error: [root@ciropom bgl-python-0.9]bjam --build-dir=/home/ciropom/Scaricati/bgl-python-0.9/ --toolset=gcc --build-type=complete stage Unable to load Boost.Build: could not find "boost-build.jam" --------------------------------------------------------------- Attempted search from /home/ciropom/Scaricati/bgl-python-0.9 up to the root and in these directories from BOOST_BUILD_PATH and BOOST_ROOT: /usr/share/boost-build. So how can I load correctly Boost.Build? The documentation speak only about a "IO streams library error", and in this case it isn't the problem. The documentation recommend to ask in mailing list.. I hope that you can help me... Many thanks for the time you spent for me! Tomasoni Danilo -- http://ciropom.homelinux.net L'apprendere molte cose, non insegna l'intelligenza. -- Eraclito

I just port a project from boost_1_33 to boost_1_36 on fedora core 6. After the program run a few minutes, it crashed and got a message: terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error> >' what(): Already open I searched the message from boost docs and google but has nothing useful. What does thi message mean? How can i catch the exception? -- Best regards, PangYongQiang

cross-platfrom binary serialization?
by Ákos Maróy 27 Sep '08

27 Sep '08

Hi, I'm working on a cross-platform project, where we're serializing data and sending it over TCP, using boost::serialization and boost::asio. As the data is quite big, and is mainly numeric, binary serialization provides a nice advantage over XML-based serialization, both in terms of performance and data size. But, I've found that the serialized data itself is not cross-platform. E.g. if I have a simple app, that sends serialized data via a TCP connection, it works fine as long as both ends of the connection are on the same platform (say both are Linux x86_64, or both are Windows XP). but they don't interact with each other - the data sent by one platform is not accepted 'as is' by the other. I wonder what provisions have to be done to achieve binary serialization that would work in such a context? Akos

Building boost 1.36 regex library on openwrt/optware
by Dustin Arnett 27 Sep '08

27 Sep '08

Hello, I am trying to build the regex boost library on my Asus wl500gP router. It has openwrt kamikaze 7.09/optware installed on it. Things may take a while to build, but they do build. But I am having problems getting this specific package to work. It is beyond me. All modules compile properly, the static library even links properly, just the regex shared library spits out these errors.

[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

Dear all. I have some problems installing this fantastic libraries.. I have downloaded the svn version (revision 338) and the 0.9 relased version, but either haven't a setup.py file that work. In bindist/ folder, there is a setup.py file, that try to install all files in bin/* directory.. but this folder does not exists! in bindist folder exists only setup.py file. So.. how can I install python bindings for boost on my fedora 9 machine?? Thank you for advice!

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
