Did you run configure?

[firstlove1992]

Of course

Can you give me more information about the system (OS). I was guessing it was due to curses not being present but configure tells otherwise.

[firstlove1992]

It seems that way.
But I reupdated the package and it worked.
Although it reports the following error, but does not affect.
By the way, my version of linux is Red Hat Enterprise Linux Server release 7.6 (Maipo).

wget https://github.com/abishekvashok/cmatrix/archive/refs/tags/v2.0.tar.gz
./configure
checking for /usr/lib/X11/fonts/misc... no
checking for /usr/X11R6/lib/X11/fonts/misc... no
configure: WARNING:

*** You do not appear to have an X window fonts directory in the standard
*** locations (/usr/lib/X11/fonts/misc or /usr/X11R6/lib/X11/fonts/misc). The
*** mtx.pcf font will not be installed. This means you will probably not
*** be able to use the mtx fonts in your x terminals, and hence be unable
*** to use the -x command line switch. Sorry about that...

[firstlove1992]

Maybe it's my version of linux.
I don't know, but it's working now.

[abishekvashok]

Closing as it is working :)

For the x fonts warning, it means you don't have fonts installed or configured and the -x option won't work properly. Maybe try the latest version instead of the release tarball?

Same problem on the current master. Ubuntu 20.04.

Can you run, @somera
gcc -g -O2 -o cmatrix cmatrix.o -lncurses -lncursesw -v

and post the output?

[somera]

$ gcc -g -O2  -o cmatrix cmatrix.o -lncurses -lncursesw -v

Okay and it compiled? Must be a problem with the make file then.

[somera]

Yes.
