4.6. Dynamic Libraries Loading

When developing your MRG Realtime program, consider resolving symbols at startup. Although it can slow down program initialization, it is one way to avoid non-deterministic latencies during program execution.
Dynamic Libraries can be instructed to load at system startup by setting the LD_BIND_NOW variable with ld.so, the dynamic linker/loader.
The following is an example shell script. This script exports the LD_BIND_NOW variable with a non-null value of 1, then runs a program with a scheduler policy of FIFO and a priority of 1.
export LD_BIND_NOW
chrt --fifo 1 /opt/myapp/myapp-server &
