I cloned the vortex master branch yesterday(2024.04.09) and built it follow the README.md. The build step run properly until I run the $ ./ci/blackbox.sh --cores=2 --app=vecadd , it returned with an error as follows:
Workload size=64 invalid caps id: 6 ../common.mk:94: recipe for target 'run-simx' failed
I checked the source code in the "runtime/simx/vortex.cpp" and found that it returns the error since there is no "VX_CAPS_LOCAL_MEM_SIZE" caps support in the simx runtime. And I found that the pocl runtime lib "libpocl-devices-vortex.so" exist a "vx_dev_caps" call in the newest library download by the "ci/toolchain_install.sh" script. I wonder is there any mismatching between the simx runtime and the pocl runtime?
