NiosII 9.1 Import Error: Makefile is not Software Build Tools compatible

[Altera_Forum]

Hi, 

I am a makefile novice. I just completed re-making our library makefile based on the nios2-lib-generate-makefile command we were previously using IDE generated commands that were no longer supported.    It turned out that a lot of the variables provided by default were not used and also the public.mk did not contain anything, so I stripped them out to improve maintainability. My makefile compiles splendidly from the command line but when I try to import it into the Nios II 9.1 Eclipse GUI, I get an error saying Makefile is not Software Build Tools compatible.    I looked in Software Developer's Handbook and read Section I and looked through Section 4 but didn't see any reference to what was required by the GUI to make the makefile compatible? It just encouraged you to utilize the autogenerated files as a basis and said you could write your own but said nothing about compatibility issues. I tried using the NiosII help search option but it caused the GUI to instantly quit?   There are a lot of documents perhaps I just missed the one that explains a minimum set of requirements for importing into eclipse for debug.

Add the following to your makefile. Also make sure it's called Makefile and not makefile. 

# -------------------------------------------------------------------------------# Following line needs to be included so the eclipse environment recognises# the project and imports it. Go figure. CREATE_ELF_DERIVED_FILES := 0    From memory it also works with a# in front of CREATE go figure.  Wasted a couple of hours of my life figuring this crap out.

Bless you, import now works and it builds too.  

I never would have figured this out.    Thanks!!!!! Jennifer

Looks like you also have to set the CREATE_LINKER_MAP variable.
