1 - In the NIOS II IDE right click on your system library project.

2 - On the left hand side of the window that pops up, click on "C/C++ Build".

3 - Click on the "Tool Settings" tab.

4 - Click on the Preprocessor section of the NIOS II Compiler.

5 - Add the "ALT_USE_EPCS_FLASH" to the list of defined symbols.
