Dynamic universal Make file [message #51060]

I want to create an "universal" dynamic Make file that we can use for all
our c projects. The projects will consist out of multiple c modules which
all will "create" a corresponding .exe file.

I managed to create a Make where all c modules and their resultant .o &
exe files end up in the same directory.

= Start Make 1
============================================================ ===

# Dynamic Make file
# for each .c module in the project (= CurDIR)
# a corresponding .o & .exe wil be created

RootPath = c:\data\ExtFiles\

CC = GCC
SRC := $(wildcard *.c)
OBJ := $(SRC:.c=.o)
EXE := $(SRC:.c=.exe)
INC = $(RootPath)\inc
LIB = $(RootPath)\lib\xxxxxxxx.lib

Phony: all clean

all: $(EXE)

(EXE): %.exe : %.o
$(CC) -o $(@) $(<) -I$(INC) $(LIB)

$(OBJ): %.o : %.c
$(CC) -c $(<) -I$(INC)

= End Make 1
============================================================ =====

However for various reason's we would like to create the following
directory structure "under" our project.

Project
|
+- src <- C source modules
|
+- inc <- includes (.h) files
|
+- obj <- result of compiles
|
+- exe <- result of links

For each Project\src\*.c a corresponding .o file is created in
Project\obj\*.o

For each Project\obj\*.o a corresponding .exe file is created in
Project\exe\*.exe

Directory Project is a subdirectory under Eclipse\Workspace\

Here is my attemp. After struggeling for 2 days, yep I'm a Make beginner,
I even wonder if it can be done. I even started looking at Make
replacements !!!

I use GnuMake and run Eclipse on a Win machine by the way.

Thanks for the help.

= Start Make 2
============================================================ ===

RootPath = c:\data\ExtFiles\

CC = GCC

INC = $(RootPath)\inc
LIB = $(RootPath)\lib\xxxxxxxx.lib

SRCDIR = $(CURDIR)/src
OBJDIR = $(CURDIR)/obj
EXEDIR = $(CURDIR)/exe

SRC := $(wildcard $(SRCDIR)/*.c)
OBJ := $(SRC:.c=.o)
OBJ := $(subst src,obj,$(OBJ))
EXE := $(SRC:.c=.exe)
EXE := $(subst src,exe,$(EXE))

all: $(EXE)

$(EXE): $(OBJ) <--+ the problem is here.
Whatever
$(CC) -o $(@) $^ $(LIB) | I do I just can't get the
|
$(OBJ): $(SRC) <--+
$(CC) -c $? -I$(INC) -o $(@)

= End Make 2 ==================================

what I was trying to say here :

> $(EXE): $(OBJ) <--+ the problem is here.
> Whatever
> $(CC) -o $(@) $^ $(LIB) | I do I just can\\\'t get the
> |
> $(OBJ): $(SRC) <--+
> $(CC) -c $? -I$(INC) -o $(@)

Is that whatever I do I cant seem to get the target to point to the
corresponding changed .o and/or .c. It keeps on seeing the while string of
all .o or .c files as dependeances. How do I point get make so far to
point only to the ONE corresponding .o or .c files.

$(CC) -o $(@) $(<) -I$(INC) $(LIB)

And similarly exe/% : obj/%.o

Thanks Stephen :)

You suggested change did not work but you have pointed me in another
direction with the \"appending\" of the directory. I did not one could to
that. I have somthing else to \"work\" with now :)

Regards Johannes.

ps. the error I get is \"No rule to make target \'exe/%, need by \'all\'.
Stop\"

I can\'t seem to get all to \"point\" to exe/% : obj/*.o

Have you though about just using autoconf, automake and libtool? You might
save yourself quite a headache...

Just a thought.

Adding and Removing Widgets [message #62178 is a reply to message #52930]

Hi All.

Did SWT api support adding and removing widgets dynamically to
org.eclipse.swt.widgets.Composite
on user interactions ?.

I didn't find any api methods to add and remove widgets.

Please advise me how to proceed.

Biju
