I see:
cc1plus.exe: out of memory allocating 363249 bytes
so there's not much we can do to address this.

Does the build work without the optimization option '-O3'?

Also, the build of libviennacl without OpenMP enabled..

Even though I have OpenMP library in my folder. Anything that I am doing wrong here?

karlrupp added a commit that referenced this issue May 6, 2014
@karlrupp
CMake: Added OpenMP to linker flags when building libaries.
804dc2e 
The OpenMP flag was only set for exectuables, leading to failures
when building libviennacl.so on MinGW.

I just pushed a tentative fix for the problem. Please pull again and let us know whether this solves the problem.

@PhilippeTillet Please fix the uninitialized variable warnings in scalar_reduction.hpp:107

karl, the problem is related with the "gomp" library that comes with MinGW. I explicitly linked that library and Voila!, the problem is solved. I did it at this

find_package(OpenMP REQUIRED)
message("Link ${OpenMP_EXE_LINKER_FLAGS}")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS} -DVIENNACL_WITH_OPENMP")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS} -DVIENNACL_WITH_OPENMP")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fopenmp")#${OpenMP_EXE_LINKER_FLAGS}")
set (omp_libs gomp) <-----
endif(ENABLE_OPENMP)

and in libviennacl folder
I have to add this:
else(ENABLE_CUDA)
if(ENABLE_OPENCL)
add_library(viennacl SHARED src/backend.cpp
src/blas1.cpp src/blas1_host.cpp src/blas1_opencl.cpp
src/blas2.cpp src/blas2_host.cpp src/blas2_opencl.cpp
src/blas3.cpp src/blas3_host.cpp src/blas3_opencl.cpp)
set_target_properties(viennacl PROPERTIES COMPILE_FLAGS "-DVIENNACL_WITH_OPENCL")
target_link_libraries(viennacl ${OPENCL_LIBRARIES} ${omp_libs}) <---

and the problem is solved.
I think a better fix for this would be to IFDEF It out for MSVC and non-MSVC stuff.

Thanks for letting us know. Does the fix I pushed above work as well?

Nope it doesnt. I think the older version was fine. The problem is with FindOpenMP.cmake where it is not able to extract the OpenMP library "gomp".
It would be better to write something like this
IF(MSVC)
ELSE()
SET (OMP_LIBS gomp)
ENDFI()
and then we can link OMP_LIBS with libviennacl.

Here is the output with ur suggested fix:

Thanks! I'll take this as a basis for a fix. I'm just a bit hesitant because I want to make sure that this does not break builds on other systems and compilers...

Absolutely, you should test this. That's why we have CMake. As a priority, do this only for MinGw
by
IF (MINGW)
ELSE()
#Other platforms
ENDIF()

I have faced this problem isn so many libraries that I am frankly tired of this. If its Win32 it is by assumption MSVC which is not the case!

As you stated above, in this case it's actually a CMake problem which we have to circumvent. I understand your frustration - all we (I'm referring to programmers in general) can do to improve this is to report any such troubles upstream in order to ensure these things get fixed ASAP. To the extent possible here, ViennaCL listens, so thanks for reporting :-)
