Application build error with trunk (9.0.0)

Runtimes OpenMP

Hi,
My application fails to build on a POWER8 machine:

[ 35%] Building CXX object nestkernel/CMakeFiles/nestkernel.dir/subnet.cpp.o

Steps to produce:
$ git clone https://https://github.com/nest/nest-simulator/
$ mkdir /tmp/build/nest-clang-offload/
$ cd /tmp/build/nest-clang-offload/
$ cmake -DCMAKE_TOOLCHAIN_FILE=Platform/JURON_Clang -DCMAKE_INSTALL_PREFIX=/path/to/opt/nest-clang -Dwith-gsl=ON -Dwith-openmp=ON -Dwith-mpi=OFF -Dwith-python=OFF -Dwith-offload=ON /path/to/nest-simulator/

Alexey - Have you pushed the fix on to upstream i.e., projects/openmp repository?
I’m still seeing a build error with -O0 flag.

I’ve just confirmed that the build (with the -O0 debug flag included) went fine
on our POWER8 system. Thanks a lot!
