[RESOLVED] No rule to make target error I can't track down

[LMHmedchem]

Hello,

I am having an annoying issue building some code.

I am getting the following error,

make: *** No rule to make target `ListObjects/gcc44/x86_64/list_tools.o', needed by `bld_CentOS-7.7_3.10.x86_64_gpp-4.8.5_gfortran-4.8.5/ListApp'.  Stop.

This is on CentOS 7.7 AMD64 with gcc/g++/gfortran 4.8.5.

The compile rule for list_tools.o is,

CC++ = g++
CFLAGS = $(OPTIMIZE) -DLINVGCC4 -DDATESTR=$(DATESTR2) $(DEFRELS) -I src -Wall
VFLAGS = -DVERNUM=$(VERNUM)
SOURCELOC = ./src

INCS = $(SOURCELOC)/utils/struct_def.h \
       $(SOURCELOC)/utils/list_tools.h

# compile list_tools.o
$(BDIR)/ListObjects/gcc44/x86_64/list_tools.o: ${SOURCELOC}/utils/list_tools.cpp $(INCS)
    $(CC++) $(CFLAGS) $(VFLAGS) -c -o $@ $<

The object is supposed to land in ./ListObjects/gcc44/x86_64/ and this directory exists

I have built this quite a few times over the last week and not had any issues. There is a leading tab on the second line of the compile rule and all of the files are in the locations where make should be looking for them. I have printed out all of the information in the rule above from make right before the compile rule, so it seems like make it getting to the right place.

How do I determine what is going wrong here?

Thanks,

Found it.

$(BDIR)/ListObjects/gcc44/x86_64/list_tools.o

actually doesn't exist. The trunk directory has many directories.

/trunk/
/trunk/src
/trunk/ListObjects
/trunk/bld_CentOS-7.7_3.10.x86_64_gpp-4.8.5_gfortran-4.8.5

where bld_CentOS-7.7_3.10.x86_64_gpp-4.8.5_gfortran-4.8.5 is where most of the compiled objects go and bld_CentOS-7.7_3.10.x86_64_gpp-4.8.5_gfortran-4.8.5 is the value of $(BDIR).

The compiled list_tools.o object actually goes in /trunk/ListObjects so the leading $(BDIR) in the compile rule is wrong. Make was looking for the directory

/trunk/bld_CentOS-7.7_3.10.x86_64_gpp-4.8.5_gfortran-4.8.5/ListObjects/etc

which doesn't exist. The correct rule is just,

./ListObjects/gcc44/x86_64/list_tools.o: ${SOURCELOC}/utils/list_tools.cpp $(INCS)
     $(CC++) $(CFLAGS) $(VFLAGS) -c -o $@ $<

Thanks for the help, really, I am surprised how often making a post helps me figure out the answer.
