[result_of?] New regression test failures on Trunk
by Richard Webb 25 Dec '07

25 Dec '07

The Trunk test results are showing that a number of new failures (e.g. xpressive/parameter/bimap) have appeared in the past couple of days. The failures appear to have occured as a result of the change to result_of.hpp for Ticket #1535 (at least, reverting result_of.hpp to the previous version allows the xpressive tests to pass on VC9). Can anyone confirm this? Thanks, Richard Webb

[dataflow] update: simple GUI dataflow editor added as an example
by Stjepan Rajko 25 Dec '07

25 Dec '07

Hello, I am getting close to wrapping up version 0.9 of the Dataflow library (I think the 9 stands for how many times I've revamped the concepts :-)). The exciting new addition is that I have completed a simple GUI dataflow editor! Screenshot: http://tinyurl.com/3cblmo I have never been more excited about making an app that doubles a number :-) For this version, I want to iron things out a bit more (docs need a ton of work) before I package it up (current code is available in the sandbox and docs on website). When the ironing is done I will request review for the generic layer and Dataflow.Signals. Dataflow.Blueprint has a long way to go but I think it shows that the generic layer is useful. And the GUI shows that Dataflow.Blueprint is useful :-) The GUI is built with FLTK (quick and easy), but I hope to switch it to the new cppgui lib at some point. Best regards, Stjepan

Venerable 403 Forbidden Problem
by Philip Garofalo 24 Dec '07

24 Dec '07

Hello, I know this has been asked before, but I'm running into the "MKACTIVITY...403 Forbidden" error when I try to commit a file. A previous response to a similar query in this message list said that you need a developer account (which I'm pretty sure I have; I've created an account with SVNManager) not just a Trac account. Okay, assuming my developer account is hunky-dory, I guess the next step, according to http://svn.boost.org/trac/boost/wiki/BoostSubversion, would be to invoke svn switch --relocate http://svn.boost.org/svn/boost https://svn.boost.org/svn/boost/ your-username/ --username Well, that would be great, but svn.exe isn't installed with Tortoise SVN, so if that's what I need to do I can't do it with just my TortoiseSVN installation. So... Is running svn switch what I really need to do? If so, do I have to download a separate installation of SVN? (That seems redundant, as TortoiseSVN appears to incorporate the functionality of SVN in one of its executables.) How can I commit my changes successfully and not get the Forbidden 403 message? Thanks, Phil

[vault] ctor_shared_from_this()
by Robert Sitton 24 Dec '07

24 Dec '07

I've had a few cases where my design required calling shared_from_this() in a constructor and destructor. I made some modifications to enable_shared_from_this which I have posted here: http://www.boost-consulting.com/vault/index.php?order=rating&direction=1&di… There is a test function in a test file in the zip archive that will fail if you call shared_from_this() instead of my ctor_shared_from_this() method.

[Units] can't view the documentation
by John Salmon 23 Dec '07

23 Dec '07

I am very interested in the recently accepted Boost.Units library. I'm interested enough that I'd really like to read the documentation.... I have checked out the sources from the svn sandbox, but I can't seem to turn the units.qbk into something more readable. I tried the "obvious": run bjam in the docs directory, but that issues the complaint below. I added 'using boostbook;' to the user-config.jam in the top-level source directory, to no avail. I fear that I'm in a maze of twisty tools, all alike. a) is there an easy way to build the documentation or b) could some kind soul who has found their way through the maze of bbv2, boostbook, xsltproc, etc. do the rest of us a favor and put the html docs up on the web somewhere. $ bjam Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (don't panic: this is a strictly optional feature). warning: No toolsets are configured. warning: Configuring default toolset "gcc". warning: If the default is wrong, you may not be able to build C++ programs. warning: Use the "--toolset=xxxxx" option to override our guess. warning: For more configuration options, please consult warning: http://boost.org/boost-build2/doc/html/bbv2/advanced/configuration.html warn: Unable to construct ./standalone error: the boostbook module is not initialized error: you've attempted to use the 'doxygen' toolset, error: which requires Boost.Book, error: but never initialized Boost.Book. error: Hint: add 'using boostbook ;' to your user-config.jam salmonj(a)drdws032.nyc$

[GIL]: extended png io
by Andreas Pokorny 23 Dec '07

23 Dec '07

Hello Lubomir, Hailin and the other boosters, I implemented support for more png file types, including palette and grayscale with alpha images. For the implementation I had to add a gray_alpha layout, and extend the color_type metafunction for homogeneous bit_aligned_pixel_* types - packed_pixel is still missing. I tested 1,2 and 4 bit images with http://www.schaik.com/pngsuite/pngsuite_bas_png.html and some images with I also added additional calls to png_packswap to get proper results for 1bit images. Could you review the changes? A svn diff of boost/gil/ is attached to the email. I have a boost svn account, and could add that stuff myself, if you want me to. I could also add more test cases that capture more of the png file types. kind regards Andreas Pokorny

That's actually not possible without changing folks library code: it's a per-library decision which is the default, with the static library being recomended as the default unless there are reasons to choose otherwise. There's a great deal of documentation that would have to change to reflect this as well. There's also a rationale for why static linking is the default behaviour in our docs here: http://www.boost.org/more/separate_compilation.html#static_or_dynamic There's a further issue with building only one variant under MSVC: it doesn't work! By only building a release build, then the only thing that will work "straight out the box" is building a release build of your application against the dll runtime. Debug builds will generate linker errors (can't find the auto-linked library etc), as will builds against the static runtime, this means that Boost will appear totally broken if users try and build the default debug builds that their IDE gives them. We need to be *very* careful with this, or the complaints will be loud and vociferous! If the aim is to reduce the number of variants built, then I would suggest: Dymanic *and* static lib, as Release, multithreaded, dynamic runtime single build on Unix variants (2 build variants). Dynamic *and* static lib, Release *and* Debug, multithreaded, dynamic runtime on Win32 compilers (that's 4 build variants). That's an absolute minimum IMO. Even then we will have to be very careful that our build instructions indicate very clearly how to build the other variants, especially for those msvc users :-) Sorry to be the bearer of the bad news, John. PS this is too important and far reaching to be discussed only on boost-build IMO.

You should probably repost this suggestion with '[lambda]' in the subject or file a feature request with a patch for that library's authors to pick it up. IIRC there was a planned merger of Lambda and Phoenix2. Itseems you have some time to contribute ITM and your "Egg" library showssome experience in that domain. I'm CCing Joel as he might be interested in your help. Getting "Factory functionality" out of the Lambda library does not deprecate the utility we are reviewing: Using Boost.Lambda just to create a single class instance seems sorta wasteful. Factory's greatest strength is its simplicity: We can easily make it compile (and optimize decently) even with legacy compilers and it's lightweight in terms of dependencies and template instantiations.
