# This script documents setting up a openEuler24 host for Velox

# * INSTALL_PREREQUISITES="N": Skip installation of packages for build.
# * PROMPT_ALWAYS_RESPOND="n": Automatically respond to interactive prompts.
#     Use "n" to never wipe directories.

# You can also run individual functions below by specifying them as arguments:
# $ ./setup-openeuler24.sh install_googletest install_fmt

# Some of the packages must be build with the same compiler flags
# so that some low level types are the same size. Also, disable warnings.
