tests fail with intel compiler

[mariomulansky]

I'm trying to get HPX running with the intel compiler on hermione by doing:

CXX=icpc cmake -DCMAKE_INSTALL_PREFIX=/home/mmulansky/hpx_intel \
    -DCMAKE_CXX_FLAGS="-gcc-name=g++-4.8" ../hpx_github/
make -j8
make install
make -j8 tests

and it seems to work fine until the tests/unit/lcos/future.cpp unit test, which fails with some errors like

home/mmulansky/hpx_github/hpx/util/preprocessed/tuple_5.hpp(1108): error: function \
    "hpx::lcos::future<R>::future(const hpx::lcos::future<R> &) [with R=int]" (declared at \
    line 741 of "/home/mmulansky/hpx_github/hpx/lcos/future.hpp") cannot be referenced -- \
    it is a deleted function

note that with g++ the tests run without problems.
Is this a bug or am I doing something wrong?

This is a bug in the Intel compiler which we already tried to workaround. However we have not been able to find a solution yet.

Please try again, @K-ballo committed a patch which should fix this problem.

The workaround only tackles that particular icpc bug. Some tests are still failing to build.

Our buildbots (testing intel13 and intel14) do compile everything again.

Intel 14 uses -gcc-name=g++-4.8 and Intel 13 uses -gcc-name=g++-4.6
