Thanks for this immensely helpful tutorial to clarify this my most confusing topic!

What a superb lecturer thanking you ever so much and thoroughly enjoyed every minute of your presentation

It's really helpful to understand what autotool do. Thanks!

The Best presentation ever made on Autotools and make tool...

Awesome Lecture. Very helpful.

Great one!

Nice presentation. I can't able to access slides for presentation can you check it once

Now this is called learning from theory to practical

This video refers to all deprecated stuff of GNU toolchains although things been moved much furthers. using autoscan utii can get started.

16:08 What is the difference between $(…) and ${…} here?

Don't like the explanation approach...Completely unsystematic.

@ is not called ampersand :P

17:04 Generate dependency files. 25:51 Library.

Hi Barry - I've created a makefile based on yours. I think I have it right but what I'm finding is that if I make the executable, run it successfully, then touch the source file to update its time stamp, when I run make again it recreates the object file but does not update the executable. Here is a screen dump showing the results: [jcl@localhost inputDouble]$ ls -lt total 8 -rw-r--r-- 1 jcl jcl 217 Jan 19 14:51 inputDouble.c -rw-r--r-- 1 jcl jcl 530 Jan 19 14:51 makefile [jcl@localhost inputDouble]$ make gcc -g -c -MMD -MP -o inputDouble.o inputDouble.c gcc -o inputDouble inputDouble.o [jcl@localhost inputDouble]$ ls -lt total 44 -rwxr-xr-x 1 jcl jcl 20872 Jan 19 14:56 inputDouble* -rw-r--r-- 1 jcl jcl 29 Jan 19 14:56 inputDouble.d -rw-r--r-- 1 jcl jcl 4104 Jan 19 14:56 inputDouble.o -rw-r--r-- 1 jcl jcl 217 Jan 19 14:51 inputDouble.c -rw-r--r-- 1 jcl jcl 530 Jan 19 14:51 makefile [jcl@localhost inputDouble]$ touch inputDouble.c [jcl@localhost inputDouble]$ ls -lt total 44 -rw-r--r-- 1 jcl jcl 217 Jan 19 14:56 inputDouble.c -rwxr-xr-x 1 jcl jcl 20872 Jan 19 14:56 inputDouble* -rw-r--r-- 1 jcl jcl 29 Jan 19 14:56 inputDouble.d -rw-r--r-- 1 jcl jcl 4104 Jan 19 14:56 inputDouble.o -rw-r--r-- 1 jcl jcl 530 Jan 19 14:51 makefile [jcl@localhost inputDouble]$ make gcc -g -c -MMD -MP -o inputDouble.o inputDouble.c [jcl@localhost inputDouble]$ ls -lt total 44 -rw-r--r-- 1 jcl jcl 29 Jan 19 14:56 inputDouble.d -rw-r--r-- 1 jcl jcl 4104 Jan 19 14:56 inputDouble.o -rw-r--r-- 1 jcl jcl 217 Jan 19 14:56 inputDouble.c -rwxr-xr-x 1 jcl jcl 20872 Jan 19 14:56 inputDouble* -rw-r--r-- 1 jcl jcl 530 Jan 19 14:51 makefile [jcl@localhost inputDouble]$ Here is the makefile: APPNAME = inputDouble CC=gcc CFLAGS= -g OUTPUT_OPTION= -MMD -MP -o $@ SRCS=$(wildcard *.c) OBJS=$(SRCS:.c=.o) DEPS=$(SRCS:.c=.d) -include ${DEPS} $(APPNAME): $(OBJS) $(CC) -o $(APPNAME) $(OBJS) clean: rm -f *.o *.d $(APPNAME) Any suggestions will be much appreciated. - Thanks - Jim

Auto tools is the worst piece of software invented. Unintelligible, extremely hard to debug, and litters your directory was junk. Just use CMake, Meson, hand-written makefiles, or even zig

Really great demonstration, thank you!
