[ALPS-users] OpenMP flags issue in ALPS 2

Hi again Matthias, I've tried your suggestion below in CMakeLists.txt, compilation is successful (as always) but in the file include.mk there is no openmp flag appearing in the compiler flags. It's strange since in the configuration process with ccmake the build system correctly recognizes the openmp flag appropriate for the compiler. This is my include.mk :

# shell

# path

In case it does not work in the link step, please try to change the top level CMakeLists.txt file in the following way:

add

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}

${CMAKE_CXX_FLAGS}")

just after the line saying

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")

and then please try if it links correctly.
