Intel support

[maeneas]

Hartmut reported that HPX supports the intel compiler.

This is what I see when I attempt to configure with intel on ranger:

[hpx.info.gcc_config] Compiler reports compatibility with GCC version 3.4.6

CMake Error at cmake/HPX_Message.cmake:29 (message):
[hpx.error.gcc_config] GCC 4.4.x or higher is required.
Call Stack (most recent call first):
CMakeLists.txt:214 (hpx_error)

Here is what I see in cmake:

CMAKE_C_COMPILER /opt/apps/intel/12.1/composerxe/bin/icc
CMAKE_C_COMPILER_WITH_PATH /opt/apps/intel/12.1/composerxe/bin/icc
CMAKE_CXX_COMPILER /opt/apps/intel/12.1/composerxe/bin/icpc
CMAKE_CXX_COMPILER_WITH_PATH /opt/apps/intel/12.1/composerxe/bin/icpc
CMAKE_Fortran_COMPILER /opt/apps/intel/12.1/composerxe/bin/ifort
CMAKE_Fortran_COMPILER_WITH_PA /opt/apps/intel/12.1/composerxe/bin/ifort

The Intel compiler is not officially supported. I suggested to Hartmut that you try this. I'll see what can be done about this after SC

[brycelelbach]

Actually, matt, it just looks like you are not setting CMAKE_CXX_COMPILER. Please configure HPX with Intel and try again

[maeneas]

Look closer. CMAKE_CXX_COMPILER /opt/apps/intel/12.1/composerxe/bin/icpc

What version of the intel compiler is that? I remember I managed to build HPX with the intel compiler version 13beta a couple of weeks ago (Added cmake checks to properly detect it even)

[sithhell]

Just saw it ... 12.1 this needs an update of the cmake scripts ... for now, it is safe to just uncomment line 214 (and related) in your copy of CMakeLists.txt. everything should build fine then

[hkaiser]

I added an option to the cmake build system allowing to ignore the version of gcc, thus continuing the build for compilers reporting older versions than 4.5.5. Add -DHPX_IGNORE_GCC_VERSION=ON to the cmake command line to enable this feature (see c8dc0c6).`

[brycelelbach]

The better option is to use the CMake compiler id to determine whether we should do the GCC version test or not.

[brycelelbach]

Can't reproduce still, and works fine for me on two machines. Will wrap up any issues during the actual compilation tomorrow.

[hkaiser]

Please describe what steps you have taken to make it work.

[brycelelbach]

Running into Boost issues, those will have to be worked on before we can investigate whether there are any HPX issues. At least it configures fine now, though.

From #638:

2e0bebf
using icpc 12.1.0 and boost 1.48.0

Here's the error I see:

hpx/hpx/util/thread_specific_ptr.hpp(184): error: "thread_specific_ptr" is not a function or static data member
struct HPX_EXPORT_THREAD_SPECIFIC_PTR thread_specific_ptr

[sithhell]

I just successfully compile HPX with the intel compiler version 13.0.1 20121010

I see you are using 12.1 any chances to upgrade to a newer version?

[sithhell]

We have a working buildbot running with the intel 13 compiler version 13.0.1 20121010. That is the only intel compiler we officially support right now.
