first time writing a make file. i either did a one line command from command line, or just let development environment automake makefile.
i am using:
Eclipse IDE for C/C++ Developers
Version: 2018-09 (4.9.0)
Build id: 20180917-1800
OS: Linux, v.5.13.0-28-generic, x86_64 / gtk 3.24.20
Java version: 11.0.13
this is what i have been able to gather off internet:
LINK_TARGET = GUI2
_DEPS = CGUI.h
DEPS = $(patsubst %,$(IDIR)/%,$(_DEPS))
_OBJS = CGUI.o Main.o
OBJ = $(patsubst %,$(ODIR)/%,$(_OBJ))
# include dir ../include
IDIR = /usr/include/qt4
CC = g++
CFLAGS = -I
# object dir ../../build/obj
ODIR = ./eclipse-workspace/GUI2
# library dir ../lib
LDIR = /usr/lib/x86_64-linux-gnu
# Define options are those defined using -D parameter (gcc),
# like -DSOME_DEFINE=1,
# those defines can be checked in code like: #ifdef SOME_DEFINE
-rm -f $(ODIR)
i have no clue what "DEFINES =" is suppose to be.
same thing happens with "DEFINES =" and "#DEFINES ="
added in a bug to code, and get same message.
make: Nothing to be done for 'all'.
14:07:11 Build Finished. 0 errors, 0 warnings. (took 554ms)
i expected "DEFINES =" or "#DEFINES =" to throw an error, but no change.
this is about the third makefile i tried. each one a little different.
What I have tried:
