Why the changes made to the Nios II Paths in Eclipse disappear everytime I close and reopen the Application Properties Window? - Why the changes made to the Nios II Paths in Eclipse disappear everytime I close and reopen the Application Properties Window? Description When user wants to add a new path (include path, libraries path) for his application in Nios II SBT for Eclipse, makefile is not updated accordingly. Changes made will not be saved and it will disappear everytime user closes and reopens the application properties window. This is a problem in Quartus II v11.1(SP1). Resolution The workaround for this issue is to manually add the path to the makefile. Locate the corresponding line in makefile and add the path to it. For example: APP_INCLUDE_DIRS = ../include/ APP_INCLUDE_DIRS =../../include2/ APP_LIBRARY_DIRS:=./ This problem is fixed in Quartus II version 12.0 and later.
