[boost.random] Dependencies/modularization
by Philip Bennefall 02 Dec '13

Hi all, I know that I have brought up this subject before and that work is being done to improve the situation, but I just wanted to ask about a specific case that I came across today while attempting to extract a subset of Boost. I want to use mersenne_twister.hpp, uniform_int_distribution.hpp and uniform_real_distribution.hpp from boost.random as part of an open source library that I am developing. Since the only part of Boost that I am using in that library is the Mersenne Twister prng, I figured I would ship the relevant headers along with my own source distribution. I used bcp to scan my code which includes these three headers, and I get a directory which is 2.89 MB in size and which contains 304 files. I looked at what is being included, and in order of size the worst offenders are as follows: preprocessor - 1.82 MB type_traits - 604 KB config - 250 KB The other libraries that are included are tiny, and I would not consider config to be a problem either. Clearly, preprocessor is the worst offender by far here in terms of bloat. I wonder if there is an easy way to get rid of the dependency on that library without hacking Boost too much? As for type_traits, it seems a bit large for what I gather it is being used for in this case but is not the end of the world either. Does anyone have any suggestions? Will the modularization of Boost reduce these dependencies in the not too distant future? I know that a huge effort is being spent moving Boost to Git, but I am curious to know whether there is a roughly estimated timeline for the modularization work? Kind regards, Philip Bennefall

[type_traits] Why is there no total extent?
by Mostafa 01 Dec '13

01 Dec '13

I was wondering why there is no total_extent in the TypeTraits library. total_extent would represent the total number of elements in a complete built-in array type, else it would be zero. I would think that this would be a natural supplement to the existing extent metafunction. (There is a very similar functionality in the smart pointers library, under the name of array_total here: smart_ptr/detail/array_traits.hpp) Mostafa

All, Looking to have ZeroMQ integration with Boost-v1.54. I am familiar with Boost.ASIO client and Server model. BTW, How do I proceed to have ZeroMQ integrated with Boost-v1.54 with GCC on Linux platform?

[conversion] Isolating the phantom file changes problem

This is the simplest case I could come up with where git clone produced a initially modified state. Any ideas why this is happening? Is this another manifestation of crlf problems? --Beman D:\modular-boost\libs\intrusive>git clone --recursive git@github.com:boostorg/boost.git modular-boost ... much output, no apparent error messages...
