Did you run configure?

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 · 2022-12-17T17:43:17Z

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).

firstlove1992 · 2022-12-17T17:46:01Z

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

abishekvashok · 2022-12-18T06:18:27Z

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?

Yes yes, will clean the make file.

Fix linker issues that prevent compillation with gcc from succeeding using autotools. This allows compilation to succeeed in Mac OS - haven't tested on linux yet. Fixes: #161 Signed-off-by: Abishek V Ashok <[email protected]>

abishekvashok · 2022-12-28T14:54:49Z

So, I tried using automake and seems I've fixed compilation issues in automake - but haven't tested it in linux yet - can someone of you help to make sure the patch works in linux as well?

PR: #163

Okay, same error, -lncursesw doesn't work in Mac, so just need to pass it in Linux, let me see.

somera · 2022-12-28T15:26:55Z

I tested this on Ubuntu 20.04.

abishekvashok · 2022-12-29T07:58:26Z

@somera hey, can you try the latest patch again (added a new commit)? It should add -lncursesw to gcc args if it detects the package in your system and display a warning otherwise if you are on linux.

somera · 2022-12-29T08:29:26Z

Strange. Now I see this

checking for main in -lncurses... yes
configure: WARNING:

*** ncurses with wide character support is packaged as a seperate library (ncursesw)

And than

This

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

is working fine.

Missing function is in ncursesw.h
Happens with configure+make as well as with cmake ..

(the old cmatrix 1.2a builds fine.)

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

gives an executeable as this links ncursesw.

maybe seperate issue:

running that gives Segmentation fault when first string hits bottom of terminal. (xterm)

fun program. might consider ditching curses dino entirely in favor of
https://github.com/tomsmeding/termio

Since nobody needs ncurses terminal abstraction (termcap) unless they're running a 1970s-80s hardware serial terminal. It's all ansi/vt100 controls today. Only the wildest edge cases are not. Only difference you'll find in practice is #colors supported.

maskimko · 2023-04-14T15:48:38Z

I solved this build issue with 2 simple things:

First I noticed that on my Amazon Linux 2, ncurses header file is called curses.h but not ncurses.h So I just id this change

diff --git a/cmatrix.c b/cmatrix.c
index 7d8ca39..d609573 100644

+++ b/cmatrix.c

 #endif

 #ifdef HAVE_NCURSES_H
-#include <ncurses.h>
+#include <curses.h>
 #else
 #ifdef _WIN32
 #include <ncurses/curses.h>

second I added -lncursesw to the LIBS variable of makefile line 217 of Makefile: LIBS = -lncurses -lncursesw
Third just make && make install

skytwosea · 2023-05-14T15:50:26Z

I had the same issue, and resolved it as per @maskimko's post; make and make install worked and cmatrix runs. However, as soon as the first text rain hits the base of my terminal, I get a segmentation fault.
kubuntu 5.15.0, using Konsole

chi-lambda · 2023-06-07T17:23:23Z

It works mostly fine for me with Debian Bullseye if I only specify -lncursesw, but not -lncurses. However, option -c (which, despite what the man page says, merely changes the output to Japanese) outputs both Japanese characters in the odd columns and ASCII characters in the even columns, with performance degrading dramatically once the screen is about 70% filled:

Lambda mode (option -m) is fine.

Maxito7 · 2023-07-03T06:18:11Z

I myself am getting this error after trying @maskimko's solution. Not really sure why it's not creating anything, though I'm at least no longer getting that waddnstr error.

Even weirder, the command works but it prints out this:

May very well be a font/terminal issue, but overall very weird

getting the above error

justinvforvendetta · 2023-10-22T21:33:56Z

@Maxito7 your error is because you used sudo make, and no sudo after with the 'make install', so permission for make to install (move the bin) without sudo was denied

justinvforvendetta · 2023-10-22T21:35:17Z

also, i do get the waddnwstr error on WSL Ubuntu 22, and definitelyu have the lib.. only solution that worked was downloading the tar.

stemid · 2023-10-25T07:08:41Z

I'm going to borrow this thread because I get the same ncurses error, but I also cannot get it working at all on Fedora 38.

It does eventually compile with this command that @abishekvashok showed; gcc -g -O2 -o cmatrix cmatrix.o -lncurses -lncursesw -v but the binary segfaults as soon as the first character reaches the bottom of the terminal. I tried this only in gnome-terminal and tmux in gnome-terminal.

Failed with make install but gcc -g -O2 -o cmatrix cmatrix.o -lncurses -lncursesw -v made it.

-lncursesw -v is the key!
