Running OpenMP code #281

Closed ashuthosh-mr closed 2 years ago

ashuthosh-mr commented 2 years ago

Hi, I wish to run OpenMP benchmark codes on a RISC-V multi-core platform. Is it possible on Vexriscv SMP since it has a runtime environment through this project? If not, are there any other ways somewhere else? Thank you

Hi, maybe via buildroot rebulding a image with the packages ? but i realy have no idea.

Hi, an update on this issue. In the config litex_vexriscv_def_config, under the section of gcc, I added these lines(found it in the issue #271 ):

GCC

BR2_GCC_VERSION_10_X=y BR2_GCC_ENABLE_OPENMP=y BR2_INSTALL_LIBSTDCPP=y BR2_TOOLCHAIN_BUILDROOT_CXX=y

The above lines are not present in the default config file. Rebuilt the buildroot images from scratch. It generated toolchains to compile that supported shared libraries such as libgomp.so.1 Now I am able to run openmp codes. Thank you.
