Installation Node Requirements

Before compiling the source code, install GCC/G++, Autoconf, and CMake on each node. Table 1 lists the version requirements.

LLVM and jemallco must be compiled on openEuler 20.03 LTS SP1 so that they can run properly on both openEuler 20.03 LTS SP1 and openEuler 22.03 LTS SP1.

Before installing OmniOperator, deploy necessary components in the cluster environment by following instructions in OS and Software Requirements.
Before configuring environment variables, check whether the environment variable LD_LIBRARY_PATH exists in your environment. If the environment variable does not exist, you do not need to add $LD_LIBRARY_PATH during configuration, so as to prevent irrelevant content from being introduced to the current path. Otherwise, security problems may occur. All environment variable export operations in this document comply with this principle. Take LD_LIBRARY_PATH as an example. If LD_LIBRARY_PATH already exists in your environment, use export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/xxx. Otherwise, use export LD_LIBRARY_PATH=/xxx.
