Mixed Implicit and Normal Rule error

[ktiwari9]

Hi there,

First of all, thank you for the amazing makefile. I am trying to learn to use it and adapt it for my project. I get the following error: Makefile.include:126: *** mixed implicit and normal rules: deprecated syntax which is generated because of the following line:

$(FIGS)/%.pdf: $(FIGS)/%.svg  ## Figures for the manuscript

Not sure how to fix it.

I've never seen that. What does make --version say?

[ktiwari9]

It says:

I think it's complaining about the ## ... comment. If you remove that comment from that line, does the error go away?

[ktiwari9]

Nope. I tried. It still complains about this line : $(FIGS)/%.pdf: $(FIGS)/%.svg

[ransford]

OK. It will take me a little time to reproduce this, since GNU Make 3.x doesn't seem to tickle this bug.

Bro I also encountered this problem about :$(OBJ_OUT_DIR)/%.o: $(CUR_DIR)/%.c

[ransford]

There's almost certainly a space in a directory name in $(FIGS) (or in the case of the most recent comment, $(OBJ_OUT_DIR)). Try renaming component directories so that they don't have spaces in their names.
