This document describes the configuration options you may use during build procedure.
This option configures needed logging capacity for target binary.
There are following parameters such as none, medium, high.
Setting none include all possible logging levels in the library that can be controlled by XLIO_TRACELEVEL environment variable.
This option manages by symbols visibility of the library.
This option manages debugging information in the executable, such as the names of variables, the names of functions, and line numbers. This allows a debugger to step through code line by line, set breakpoints, and inspect the values of variables. Final binary file size is increased.
This option allows to use the library with popular open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more as NGINX.
This option enables uTLS HW offload for supported NVIDIA HW.
This option allows to use DPCP library for programming Infiniband devices. DPCP (Direct Packet Control Plane) is mandatory to enable advanced HW features for supported NVIDIA HW. This library should be installed on your system.

This option enables socket api profiling information after application exit using libibprof profiling library. This library should be installed on your system.
