Why do we need to create the file "compile"? can't the timestamp of source(after compilation) be directly compared with the timestamp of source.c(the source)?

[adityabankar]

@ART000747 Yes we can do so. I took a different approach here. Sometimes we would want to do tasks that won't generate files with name "source" for "source.c", for example VHDL/Verilog compilation. In such cases it is required to follow this approach. After all Makefiles can be used for tasks other than C compilation.

@adityabankar Thanks for the reply, i tried to replace "touch compile" with "source" but gives me error.How exactly can this be done.

Here is the code:

exec: \

compile ./source

compile: \

source.c gcc source.c -o source  echo " compiling the source now " source

@ART000747 actually touch is the command that updates the time stamp of an existing file to current system time. If the file doesn't already exist then it creates the file. There is no such command as source thus there is an error. To do what you wanna do you must rename compile: to source: and remove the statement "touch compile".

Here is the code:

exec: \

compile ./source

source: \

source.c gcc source.c -o source echo " compiling the source now "

Why is it always indians doing these tutorials???

[adityabankar]

@AppleHack23 I was not aware if more Indians were doing it. But if you see at the bottom a user called "themanyone" has also done it and he is not an Indian.

In the batch File you can read line of text file like this:

set /p var= <Text.txt

echo %var%

But how can you do it in the makefile (To read a Line of text File or the whole text)?

I want to read a file and print the contents.

@AppleHack23: Indians are awesome!

When I had to learn how to use Hibernate, I saw another tutorial by an Indian.

Apparently they are pretty good at their stuff, and helpful, plus I love the Indian accent ^^
