[mekefile] define const

[whired123]

Can you do it?

$ cat makefile
const ABC = 123

$ make
makefile:1: *** missing separator.  Stop.

It seems not to me ...

 

[dos2unix]

const ABC = 123

all:
    echo $(ABC)

Every command has to have a [tab] before it. Not spaces. It is a requirement.

You need to read this.

GNU make

GNU make

www.gnu.org

$ cat -T makefile
const ABC = 123

all:
^Iecho $(ABC)



$ make
makefile:1: *** missing separator.  Stop.

AFAIK, there is no "const" keyword in the Makefile syntax for GNU make. That's almost certainly where you're going wrong.

 

[whired123]

So the makefile constants do not exist?

No, not unless it's something that has been recently added to GNU make.
I'm still using Debian 11 (oldstable) so I might be a bit behind the times. But AFAIK there has never been a const keyword in the Makefile syntax.
