No rule to make target '-L/usr/local/lib'

I am facing a problem while trying to link opencv to CPP project generated by Matlab Coder. In the auto generated Makefile of the project, I added pkg-config --cflags opencv to CFLAGS and pkg-config --libs opencv to LIBS (opencv 3.4), which then gives the error "No rule to make target '-L/usr/local/lib'". Any ideas how to fix ther error?

Solution

  • Your makefile has the variable assignment (edited for brevity)...

    LIBS = $(MATLAB_ROOT)/bin/glnxa64/libmwjpegreader.so ... $(shell pkg-config --libs opencv)

    Where the $(shell pkg-config --libs opencv) component will expand to something like...

    -L/usr/local/lib -lopencv

    But you then use $(LIBS) as a dependency for several targets, e.g...

    $(PRODUCT) : $(OBJS) $(PREBUILT_OBJS) $(LIBS)

    which expands to (again, edited for brevity)...

    $(PRODUCT) : $(OBJS) $(PREBUILT_OBJS) -L/usr/local/lib -lopencv

    Hence, when make attempts to process the target $(PRODUCT) it will see that the target seemingly depends on -L/usr/local/lib and act accordingly.

    It's difficult to provide a more complete answer without more context but $(LIBS) probably shouldn't be listed as a dependency for this or any other targets.
