I will share the solution of the following error received during the installation of Oracle 11gR2 Software.
Error :
| 
					 1 2 3  | 
						Error in invoking target ‘agent nmhs’ of makefile  ‘/u01/app/oracle/product/11.0.0/db1/sysman/lib/ins_emagent.mk’. See  ‘/u01/app/oraInventory/logs/installActions2021–08–12_04–21–06PM.log’ for details.  | 
					
Solution :
Enter $ORACLE_HOME/sysman/lib/ins_emagent.mk.
| 
					 1  | 
						$ vi $ORACLE_HOME/sysman/lib/ins_emagent.mk  | 
					
Search the $(MK_EMAGENT_NMECTL) line and change it as follows.
| 
					 1 2  | 
						#$(MK_EMAGENT_NMECTL) $(MK_EMAGENT_NMECTL) -lnnz11  |
