Clone warnings in lexical_cast
by Tom Kent 09 Jan '20

09 Jan '20

I just ran a: git clone --recursive https://github.com/boostorg/boost boost_root and I got some warnings in lexical_cast: Cloning into 'D:/teeks99-09/boost_root/libs/lambda'... Cloning into 'D:/teeks99-09/boost_root/libs/lexical_cast'... warning: unable to unlink 'D:/teeks99-09/boost_root/.git/modules/lexical_cast/objects/b1/102161720ea50668a5756828409400a4314744.temp': Invalid argument warning: unable to unlink 'D:/teeks99-09/boost_root/.git/modules/lexical_cast/objects/8a/0a6c194259a9a3fa24ea3fb815899bfcbfed64.temp': Invalid argument warning: unable to unlink 'D:/teeks99-09/boost_root/.git/modules/lexical_cast/objects/47/dd68ef6ee5c02257a57d03ac9e611a68893d0d.temp': Invalid argument warning: unable to unlink 'D:/teeks99-09/boost_root/.git/modules/lexical_cast/objects/02/b86ef5bcc4574e5c03b75ed463dbb5ada446c9.temp': Invalid argument warning: unable to unlink 'D:/teeks99-09/boost_root/.git/modules/lexical_cast/objects/c2/b4875ef060ea7de75feceb1f20284766128325.temp': Invalid argument Cloning into 'D:/teeks99-09/boost_root/libs/local_function'... I don't think these are an issue necessarily but it might be something that can be cleaned up. Tom

[Graph] Large incoming changes to Boost.Graph master.
by John Maddock 08 Jan '20

08 Jan '20

Dear all, Boost.Graph has had no maintainer for some time, but the CMT has been busy fixing bugs none the less. Unfortunately, other than some trivial fixes to docs and some directory refactoring, nothing much has been merged to master in a good while . On the plus side, develop is now in a better tested tested state than IMO it has ever been, however the change set is rather large so the potential to mess up somebodies code is certainly there: https://github.com/boostorg/graph/pull/196. So... this is both a heads up, and a plea: if you have any mission critical code using the Graph library, could you please test against current develop and report any problems? If you don't want to mess about with git, download from https://github.com/boostorg/graph/archive/develop.zip and place zipfile-contents/libs/graph/include in your include path ahead of that for Boost-1.72. Many thanks, John.

What happened to Boost.Nowide?
by Alexander Grund 08 Jan '20

08 Jan '20

Hi, I'm a user of (a fork of) Boost.Nowide and already fixed some issues I found and was looking into getting them upstream. I also wanted to know, if it is finally in Boost. Unfortunately this does not seem to be the case. I found https://lists.boost.org/Archives/boost//2017/06/236475.php which accepted it into Boost. This is from mid-2017 and nothing has happened since. Does anyone know what the status of Boost.Nowide is? It seems the filestream parts are now incorporated into Boost.FileSystem. So it seems only cin/cout/cerr, the args wrapper and the C-functions (fopen, ...) are missing. Especially the first 2 are very useful in writing cross-platform code. Might those be integrated into some other Boost Library? Thanks, Alex

Retirement as Review Wizard
by Ronald Garcia 07 Jan '20

07 Jan '20

Dear Boosters and Boost Steering Committee, After roughly 14 years as a Boost Co-Review Wizard, I feel that the time has come for me to step down from the position, and make room for a new face with fresh ideas. It has been my pleasure to serve in this position for this time alongside first Tom Brinkman and now John Phillips. I look forward to seeing what the next 14+ years of Boost brings! Sincerely, Ron Garcia Boost Co-Review Wizard

Query on Project Multiprecision/Math GSoC 2020
by Christopher Kormanyos 06 Jan '20

06 Jan '20

Dear Boost Is there a place to post and describe a potentialGSoC 2020 project? We have a potential project for GSoC 2020. It involvessignificantly extending the precision of Boost.Multiprecisionand harmonizing these extensions and tests with Boost.Math.I have the proposal worked out in plain text and would liketo post it or share it. We have discussed this project (in PM) with the knownrecent authors and maintainers of Multiprecision and Math,and interest is strong. On a personal note, my name isChristopher Kormanyos, previous three-time Boost GSoCmentor. In previous years, I have also contributed to bothMath and Multiprecision. Thank you and kind regards, Chris

It depends on the size of the documentation. For 'trivial' documentation, the Doxygen and Markdown combination is acceptable, but I believe strongly that the best Boost documentation is done using the Quickbook toolchain (including Doxygen syntax comments to provide a references section). A killer feature of Quickbook is the ability to include code snippets from actual C++ examples that can be run, ensuring that what you get is what compiles and runs. As a mark-up language Quickbook is pretty obvious (apart from the gotcha of using indent-spaces as a way to add code sections - a common but quick'n'dirty markup feature that can cause some confusion).

Boost ASIO
by live man 03 Jan '20

03 Jan '20

Hi, We have been using Boost for our firmware product which runs in ARM processor. However for development we make use of Visual Studio IDE. We also have our own TCP / IP suite which defines its own socket.h file. We are facing issue related to using Boost ASIO in Windows development platform. It seems that the library by default includes windows networking header files - which we do not want. Instead we want Boost ASIO to make our own library socket headers and declaration. We noticed that if we include Boost ASIO and our TCP / IP socket declaration we get re-definition error and compilation fails with lots of errors? Please let us know how we can resolve the issue with the objective mentioned above? Thanks in advance. Regards, Prakash

Recomended way of generating documentation
by Alexander Grund 01 Jan '20

01 Jan '20

Hi, I'm currently in the process of generating documentation in a Boost usable format and got a couple questions. The documentation is currently in-source in Doxygen format and has a markdown file for the start page. 1. Which aliases do I need and for what? I've seen boostdoc and boostrelease but couldn't find a description what and why they are 2. Where do the documentation files need to go? It seems using BJam naively outputs them to bin.v2 not to the libraries doc folder which I'd even see useful because generated files should not clobber the source tree 3. What benefit is there going from Doxygen (over multiple conversions) to boostbook? Can't I just go from Doxygen to HTML? 4. If the above: Calling `doxygen mylib.html` in BJam generates a mylib folder and a mylib.html redirecting into that folder. Both hardcoded to go into a subfolder of bin.v2. How is that useful/useable? Wouldn't I want a 'html' folder and an index.html redirecting to the index.html contained or no redirection file at all? 5. As I'm thinking about calling doxygen manually: Do I need to do anything so e.g. mylib shows up in boost/doc/html? Why is only a subset of the libraries there? Thanks for any help or pointers!

Boost-GIL GSOC 2020
by Siddhartha Sen 31 Dec '19

31 Dec '19

Hello, I would like to propose an idea for GSOC 2020. I would like to re-implement pre existing features in Boost-GIL for example inverting an image, conversion from black and white to colour and vice versa, etc, but with the usage of parallel programming in order to improve the efficiency and speed things up. This is nothing but an idea merely, as I have some idea with parallel programming beforehand. Could anyone give me some guidance as in how to proceed with this? And also do you all think this is a good enough proposal? I already have built a couple of libraries for image conversion using openmp, but I am not sure whether they are boost compatible or not. Thank You.
