Whilst building a simple Nios program, i keep getting an error.

Question

Hi,

Whilst building a simple pre-made Nios program i keep getting the error....

/cygdrive/c/altera/12.1/nios2eds/components/altera_hal/build/gnu_rules.mk:86: *** multiple target patterns. stop.

I've attempted to search for what it means but i just can't find the answer. Has anyone seen this error and would like to help me out please?

Any help is much appreciated!

I'd look at line 86 of the specified file and see what is there.

A good guess would be something caused by spaces in filenames.

make really isn't designed to handle them at all.

I really don't know why the windows GUI ever allowed them, windows command line (cmd.exe) has no way of quoting them either.

(The GUI could have saved them an '_' instead).

I checked line 86 and it's just comments. None of my file names have spaces in them. I've only used a-z and the underscore (_) to separate words.

The folder in which is project is in c:

I have no idea at all why this error message is appearing. :(

Make won't like : in pathnames on dependency lines either.

(They can be substituted from variables, but must not be in the makefile itself)

Using relative pathnames with / as a separator is generally best.
