Thanks Daniel. I go the following errors and some segmentation fault. Is there any additional option to set:?

Has anyone successfully compiled boost and application with boost with CLANG compiler?If yes, would you mind sharing the steps?

Sure, follow the Boost compilation docs and set your toolset to clang.
Here's an example invocation that should get you started:

    ./bootstrap.sh --with-toolset=clang --prefix=${where}
    ./b2 -j $(nproc) toolset=clang cxxflags="-std=c++11 -stdlib=libc++"
linkflags="-stdlib=libc++"
    ./b2 install --prefix=${where}

You may want to remove the libc++ flags if you want to build against
libstdc++ instead.

Hi,

I am looking into the documentation of hana to merge two or more maps, say:

#include <boost/hana.hpp>

namespace hana = boost::hana;

int main(int argc, char **argv) {

    constexpr auto m1 = hana::make_map(
            hana::make_pair("key1"_s, hana::type_c<std::string>),
            hana::make_pair("key2"_s, hana::type_c<std::string>)
        );

    constexpr auto m2 = hana::make_map(
            hana::make_pair("key3"_s, hana::type_c<std::string>),
            hana::make_pair("key4"_s, hana::type_c<std::string>),
            hana::make_pair("key5"_s, hana::type_c<std::string>)
        );

    // Merge two or more maps?
    constexpr auto result = m1 + m2;

    return 0;
}

I'm not sure how to do this, probably taking the first map and for every
pair in the subsequent map return an insert? In pseudo code:

constexpr result = hana::insert(hana::insert(m1, pair1), pair2);

Can someone give me some pointers in the right direction?

Regards, Matthijs

Subject: [Boost-users] [test] Init framework before dataset generation
Message-ID: <npjuv0$20e$1@blaine.gmane.org>
Content-Type: text/plain; charset=utf-8

Hello,

I try to use boost test with data test cases:

std::vector<float> fibonacci() {
  std::cout << "Data Set" << std::endl;
  [...]
}

BOOST_DATA_TEST_CASE(datatest, boost::unit_test::data::make(fibonacci()), mapping)
{
  std::cout << "Datatype" << typeid(mapping).name() << std::endl;
}

The problem of that is, that fibonacci is initialized before anything else. The order of initializations is:

Data Set
main
init_unit_test
Global Fixture

That works fine here, but my fibonacci uses MPI which needs to initialized by MPI_Init. I want to do that initialization in the global fixture or int main or init_unit_tests, once for the entire test runner.

Is there anything I can do about that and belay initialization of Data Set after one of the others?

Thanks,
Florian
