Directory Structure :

1. 5gnr_opensource/build/ : contains files required to compile the code
   a. common : contains individual module's makefile
   b. config : contains SSI memory configuration
   c. odu    : contains main makefile to generate an executable binary
   b. scripts : contains scripts required for compilation
	
2. 5gnr_opensource/src/ : contains layer specific source code
   a. 5gnrmac : MAC source code
   b.	5gnrrlc : RLC source code
   c. cm : common, environment and interface files
   d. cu_app : Stub code for CU
   e. du_app : DU application and F1 code 
   f. mt : wrapper functions over OS
   g. phy_stub : Stub code for Physical layer
   h. rlog : logging module


Pre-requisite for Compilation :
1. Linux 32-bit/64-bit machine
2. GCC version 4.6.3 and above
3. Copy ASN code generated for F1 messages into 5gnr_opensource/src/du_app/F1AP/asn/

How to Compile :
1. cd 5gnr_opensource/build/odu
2. To clean and compile: make clean_all odu  MACHINE=BIT64 TEXT_LOG=YES
3. To clean only, run command : make clean_all MACHINE=BIT64 TEXT_LOG=YES

Executable binary generated : 5gnr_opensource/build/odu/obj/odu
