BOOST 1.33 msvc/gcc
by Nadine Faizant 22 May '07

22 May '07

Hello, I'm testing same code compiling under MSVC 8.0 or gcc 3.4.2 on the same machine. I face two different problems around boost::dynamic_bitset : - with msvc version : dynamic_bitset allocation is very, very slow (compare to gcc execution time), - with gcc version, it seems (i'm quiete sure) that dynamic_bitset allocation take more and more time after several hours of intensive use. The two problem sound like a problem around dynamic_bitset allocation. Somebody did notice that ? Thanks for your help, Nadine

problem building asio on Windows
by Yunior Peralta González 22 May '07

22 May '07

I tried to build boost in Windows using bjam and I made it without any error (I just compiled the thread library). the problem came when I included asio.hpp I think that's because not all thread libraries were installed (just 6 files were installed) when I did the same in Debian I got just 4 files and also had errors with asio, but when I installed this way: ./configure --with-libraries=thread sudo make install instead of bjam, I got 10 files and asio worked perfectly. I'm not sure but if I need the 10 files as I guess I think that I'm not be able of using asio on Windows, but this is a contradiction because asio like boost is a multi-platform set of libraries. I'm very confused and I'll be very grateful if you try to help me.

[Boost.asio] daytime server example doesn't work.
by Schrotti 22 May '07

22 May '07

Hello, I have a problem with compiling the daytime server example of the Boost.asio tutorial (http://asio.sourceforge.net/asio-0.3.7/doc/tutorial/tutdaytime2src.html) I always get an exception which says "A File which already exists can't be created". Does anyone know the reason of the problem? btw: I'm using Boost 1.33.1 under Windows XP Sp2 with the MS Visual Studio IDE (express) and its compiler. Thanks for your efforts, Schrotti.

Using asio SSL
by Daniel Adolfsson 22 May '07

22 May '07

Hello. I'm trying to write a small FTP client using asio, and I'm having trouble getting SSL/TLS working. What I want to do is to connect to the FTP server normally, and send "AUTH TLS" in cleartext to the server, and if successfull switch over to SSL. I have tried to use a ssl::stream to connect to the server, and while not in SSL mode, using async_write() / async_read_until() with stream_.next_layer(). This works fine, and everything is sent, but when the client enter SSL mode, the server only receives junk from the client, while the client receives good responses from the server. I've checked and double checked- I am using stream_ while in SSL mode, not stream_.next_layer(). So, async_read_until() seems to work with stream_ in SSL mode, but async_write() doesn't. Any ideas? Is there a better way to do this? Daniel

I had forced it to use socket_select_interrupter because the pipe_select_interrupter wasn't compiling due to (what I thought was) a lack of a pipe implementation on VxWorks. I have since got this configured correctly, so pipe_select_interrupter seems to work ok. socket_select_interrupter also works with the bzero() call I had in my original post. -- /************************************** * Scott Finley * Research Software Engineer * TomoTherapy Inc. * Email: sfinley(a)tomotherapy.com * Phone: 608.824.3381 ***/

Filesystem problems

How do you get the path class to accept a windows drive letter? Suppose I have a dir named c:\Foo, the path constructor throws for every combo I can think of c:\\Foo, etc. I can however, say /Foo and everything works. Using boost1_33_1, VS 2005, XP Pro SP2 and linking with libboost_filesystem-vc80-mt-s-1_33_1.lib

[serialization] exception in text_iarchive constructor
by Krishanu Debnath 22 May '07

22 May '07

Hello, I get exception from text_iarchive constructor when I try to read a previously saved(serialized) file. This doesn't happen every time. It only happens when I try to run the test case through regression tcl script(I am not sure if this piece of information is of any help). I get either stream error or St9bad_alloc( bad_alloc ?). When I get exception If I try to read the file using getline, it fails too. ifstream::good() returns true before calling text_iarchive/getline though. If I use file command on that 'saved' file, I get following: "ASCII text, with very long lines, with no line terminators" As you can understand I can't reproduce this in a small testcase. I have no clue what's going wrong here. Any sort of help will be helpful. Thanks, Krishanu

I am on a Mac with OS X 10.4 and trying to compile the boost/Python examples in tutorial or quickstart using Bjam v3.1.14 OS=MACOSX. I issue the following command in the boost_1_34_0/libs/python/libs/ example directory bjam --toolset=darwin test I receive the following errors: Jamroot:18: in modules.load rule python-extension unknown in module Jamfile</Users/arthurcoleman/ Boost/boost_1_34_0/libs/python/example>. /Users/arthurcoleman/Boost/boost_1_34_0/tools/build/v2/build/ project.jam:312: in load-jamfile /Users/arthurcoleman/Boost/boost_1_34_0/tools/build/v2/build/ project.jam:68: in load /Users/arthurcoleman/Boost/boost_1_34_0/tools/build/v2/build/ project.jam:170: in project.find /Users/arthurcoleman/Boost/boost_1_34_0/tools/build/v2/build- system.jam:237: in load /Users/arthurcoleman/Boost/boost_1_34_0/libs/python/example/../../../ tools/build/v2/kernel/modules.jam:261: in import /Users/arthurcoleman/Boost/boost_1_34_0/libs/python/example/../../../ tools/build/v2/kernel/bootstrap.jam:132: in boost-build /Users/arthurcoleman/Boost/boost_1_34_0/libs/python/example/boost- build.jam:7: in module scope Can someone help me since I can't figure out what I'm doing wrong. By the way, I have tried as a superuser and get the same errors. It seemed that I was able to successfully install boost from the boost.../build director with the ./configure --toolset=darwin --show- libraries ect. Thanks in advance, Arthur

No problem: --- class A { public: pqxx::result test(const std::string &rString, const std::string &rDesc = std::string()) // fatal error // pqxx::result test(const std::string &rString) // OK { return pqxx::result(); } pqxx::result test1(void) { return pqxx::result(); } }; int main(int argc, char* argv[]) { A a; BOOST_AUTO(rs, a.test("SELECT 1")); // fatal error (when used A::test(const std::string &rString, const std::string &rDesc = std::string())) ... } --- So when I use the first signature (pqxx::result test(const std::string &rString, const std::string &rDesc = std::string()) there is fatal error.
