Neither of these seem to work, i.e. the invoked compiler is the native compiler g++ and not the cross-compiler specified in user-config.jam. Try putting user-config.jam into tools/build/src and see if it finds it there. If not, you can run b2 —debug-configuration and it will output where it searches for user-config.jam (and other components). — Noel

[boost-test] question about using templates for tests
by Damian Vicino 20 Jul '14

20 Jul '14

Hi, I’m trying to test a template with different parameters and I can’t figure out how to do it for the following case. My class is something like this: template<class T, class M, template<class, class> class F> class C { T t; M m; F<T, std::shared_ptr<C<T, M, F>; Public: … } So my test, should receive 3 template classes, first 2 normal classes and a third which receives 2 Template Parameters. For now I’m just duplicating the tests for each implementation I write for F and they pass. Anyway, it is starting to be hard to maintain, a template solution would be great. F is suppose to receive a priority_queue like parameter, something getting a value and a comparison operator. For example, this is one of the parameters I’m testing with: template <class VALUE_TYPE, class COMPARE_TYPE> using priority_queue_vector = std::priority_queue<VALUE_TYPE, std::vector<VALUE_TYPE>, COMPARE_TYPE>; Is it possible to do this with current Boost.Test? Thanks in advance

[clang] Using clang in Windows
by Edward Diener 19 Jul '14

19 Jul '14

Just a note to everybody about using clang in Windows. I upgraded the latest clang-linux.jam file in Boost Build on the 'develop' branch so that clang in Windows using gcc should now work for the purposes of testing Boost libraries. If you get the latest clang and build it on Windows using CMake with any of the mingw generators or Ninja, you will have a clang executable which will default to a target using gcc headers and libraries. If you add a line in user-config.jam such as: using clang : : yourpath/clang++.exe ; then you should be able to execute: b2 toolset=clang in order to run tests from withion a test directory for any Boost library using clang as your compiler. The output looks very good without any of the problems I have seen before when running clang in Windows. Just make sure you switch to the Boost Build 'develop' branch and pull the latest source. I have been successful so far when running tests of preprocessor, mpl, type_traits, and tti with clang in Windows. I will test some more libraries but so far it looks to me that the clang developers have finally created a version under Windows which can be used to successfully test Boost libraries. This adds one more reliable testing environment under Windows. Now I can use the latest clang, various flavors of gcc under mingw, and various flavors of VC++.

Re: [boost] Portable robust mutex an another try...

Then I think to extend it with time stamp as Niall Douglas wrote. I just need atomic CAS for 64bit. Cause the time stamp and process ID must be changed in one shot. Then I can skip many robust checks, if the time from last lock is shorter than some predefined interval. So many regular locks will neither test file lock and it will run faster. In case one process die, there will be expired timeout and lock candidate will go check file lock. I'll check if I can add a 64bit CAS in boost\interprocess\detail\atomic.hpp. (if you know how it should be done, it will be a big help for me, cause I have not a lot of practice in atomic portable world.) regards -- Sopko Ladislav 3D Informatica, Via Speranza 35, 40068, S.Lazzaro di Savena - Bologna, Italy Tel: +39051450844 | Fax: +39051451942 WWW: http://www.3di.it Documentation: https://intra.3di.it/manuali/ - http://wiki.3di.it FTP: ftp://ftp@ftp.3di.it, Download:/3di, Upload:/incoming **** Informativa Privacy - Ai sensi del D.

regex iterator memory leak
by Marjan Yahyanejad 18 Jul '14

18 Jul '14

I am using the example code of regex iterator in http://www.boost.org/doc/libs/1_55_0/libs/regex/doc/html/boost_regex/ref/re… , in a linux machine with default boost config which means NON RECURSIVE, and 4096 block size , I run the example with mtrace , setting it at first line of main method and doing muntrace right before return 0, I see that 4096 bytes get lost based on mtrace logs. if there are no flaws in my test, then is there something I should separately call to free up that memory? Otherwise that blocks seems lost to me. The original reason I started this test was that I have a similar code, and I see memory corruption on my machine which is causing connection drops to my rabbitmq server and it goes away as soon as I comment out the following three lines. So I think there is something wrong with the memory allocations of boost regex iterator. boost::sregex_iterator m1(text.begin(), text.end(), expression); boost::sregex_iterator m2; std::for_each(m1, m2, &regex_callback); Thanks --

Parallel Sorting Algorithms
by Melkowski, Kevin M. (MU-Student) 17 Jul '14

17 Jul '14

I noticed on the google summer of code page that multi-threading and sorting algorithms such as the Radix Sort was a big interest right now. I’ve been developing an open-sourced parallel Radix Sort for a while now and wanted to submit it to a library. This algorithm sorts positive and negative values for each standard data type. The code I have can be found here: https://github.com/Kevincav/Radix-Sort. When running tests for this, on my laptop I managed to sort 1 billion uniformly distributed floats in about 45 seconds. When I tested std::sort with the same test it never finished, it sorted 100 million floats finished around that time though. This is optimized for both C and C++ programs, the documentation isn’t done yet so that’s one thing I still need to finish. This is my first post and I tried to follow the guidelines, hopefully it wasn’t a bad first post. Thanks for reading, Kevin

[detail] Disabling Warnings in Jamfile
by Axel Ismirlian 17 Jul '14

17 Jul '14

I am trying to build and compile the detail tests on AIX 6.1 with gcc, but there is one small problem on the very last test: gcc.compile.c+ + ../bin.v2/libs/detail/test/container_fwd/container_fwd_debug.test/gcc-4.8.1/debug/container_fwd_test.o In file included from /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/4.8.1/include/c+ +/cstddef:41:0, from ../boost/config/select_stdlib_config.hpp:18, from ../boost/config.hpp:44, from ../boost/detail/container_fwd.hpp:16, from ../libs/detail/test/container_fwd/container_fwd_test.cpp:6: /opt/freeware/lib/gcc/powerpc-ibm-aix6.1.0.0/4.8.1/include/c+ +/powerpc-ibm-aix6.1.0.0/bits/c++config.h:277:4: error: #warning currently using inlined namespace mode which may fail without inlining due to lack of weak symbols [-Werror=cpp] # warning currently using inlined namespace mode which may fail \ ^ cc1plus: all warnings being treated as errors "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -pedantic -Werror -g -fPIC -fpermissive -g -ftemplate-depth-300 -pedantic -Wstrict-aliasing -fstrict-aliasing -Wextra -Wsign-promo -Wunused-parameter -Wconversion -DBOOST_ALL_NO_LIB=1 -D_GLIBCXX_DEBUG -D_STLP_DEBUG -I".." -c -o "../bin.v2/libs/detail/test/container_fwd/container_fwd_debug.test/gcc-4.8.1/debug/container_fwd_test.o" "../libs/detail/test/container_fwd/container_fwd_test.cpp" If I disable warnings being treated as errors through the Jamfile, the test functions correctly, but how do I customize the Jamfile file for AIX? Is it ok for me to simply ignore this warning? Also I was having a difficult time fully understanding what an inlined namespace is.

merging the super-project
by Eric Niebler 17 Jul '14

17 Jul '14

I recently made a tweak to the .gitignore of the super-project on the develop branch. How do I merge that to master? The two branches have different histories, so a regular git merge balks. And when I checkout master (thinking I'll just cherry-pick), I end up with a slew of local changes (which I haven't made). Befuddled, Eric
