ncurses not found, trying to compile iftop

[ovacikar]

Hi Folks,

I am trying to compile iftop on picore 14 running on Rpi model B , last source release was from 2014 : https://pdw.ex-parrot.com/iftop/download/iftop-1.0pre4.tar.gz

I am not able to get the configure script to detect ncurses. I have ncurses-dev extension installed, and even copied ncursesw folder to curses and ncurses

Code: [Select]

tc@box:/mnt/mmcblk0p2/tce/iftop-1.0pre4$ sudo find / -name *curses*.h
/usr/local/include/ncurses/curses.h
/usr/local/include/ncurses/cursesapp.h
/usr/local/include/ncurses/cursesf.h
/usr/local/include/ncurses/cursesm.h
/usr/local/include/ncurses/cursesp.h
/usr/local/include/ncurses/cursesw.h
/usr/local/include/ncurses/ncurses.h
/usr/local/include/ncurses/ncurses_dll.h
/usr/local/include/curses/curses.h
/usr/local/include/curses/cursesapp.h
/usr/local/include/curses/cursesf.h
/usr/local/include/curses/cursesm.h
/usr/local/include/curses/cursesp.h
/usr/local/include/curses/cursesw.h
/usr/local/include/curses/ncurses.h
/usr/local/include/curses/ncurses_dll.h
/usr/local/include/ncursesw/ncurses_dll.h
/usr/local/include/ncursesw/ncurses.h
/usr/local/include/ncursesw/cursesw.h
/usr/local/include/ncursesw/cursesp.h
/usr/local/include/ncursesw/cursesm.h
/usr/local/include/ncursesw/cursesf.h
/usr/local/include/ncursesw/cursesapp.h
/usr/local/include/ncursesw/curses.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/curses.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/cursesapp.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/cursesf.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/cursesm.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/cursesp.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/cursesw.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/ncurses.h
/tmp/tcloop/ncurses-dev/usr/local/include/ncursesw/ncurses_dll.h
and the configure script checks for all three variants:

Code: [Select]

{ $as_echo "$as_me:${as_lineno-$LINENO}: checking for a curses library containing mvchgat" >&5
$as_echo_n "checking for a curses library containing mvchgat... " >&6; }
oldLIBS=$LIBS
for curseslib in ncursesw curses ncurses ; do
    LIBS="$oldLIBS -l$curseslib"
    cat confdefs.h - <<_ACEOF >conftest.$ac_ext
/* end confdefs.h.  */

#include <$curseslib.h>
And config.log shows it is failing for all 3:

Code: [Select]

configure:5740: checking for a curses library containing mvchgat
configure:5760: gcc -o conftest -g -O2   conftest.c -lpcap -lm  -lncursesw >&5
conftest.c:45:10: fatal error: ncursesw.h: No such file or directory
   45 | #include <ncursesw.h>
      |          ^~~~~~~~~~~~
compilation terminated.

configure:5760: gcc -o conftest -g -O2   conftest.c -lpcap -lm  -lcurses >&5
conftest.c:45:10: fatal error: curses.h: No such file or directory
   45 | #include <curses.h>
      |          ^~~~~~~~~~
compilation terminated.

configure:5760: gcc -o conftest -g -O2   conftest.c -lpcap -lm  -lncurses >&5
conftest.c:45:10: fatal error: ncurses.h: No such file or directory
   45 | #include <ncurses.h>
      |          ^~~~~~~~~~~
compilation terminated.
What is happening? I will try to attach the complete config.log

Thanks in advance!

The includes are incorrect, they should read, for example:

#include <ncursesw/ncursesw.h>
#include <ncursesw/curses.h>

[ovacikar]

The includes are incorrect, they should read, for example:

#include <ncursesw/ncursesw.h>
#include <ncursesw/curses.h>

And what would be the remedy?  I tried with
1- ./configure --includedir=/usr/local/include/ncursesw/ , same error
2- modified the configure script line #include <$curseslib.h> to #include <ncursesw/$curseslib.h> , same error
3- hard coded the include line to #include <ncursesw/curses.h> , which passed the configure.

checking for a curses library containing mvchgat... -lncursesw

But then make failed with:

Code: [Select]

gcc -DHAVE_CONFIG_H -I.     -g -O2  -MT edline.o -MD -MP -MF .deps/edline.Tpo -c -o edline.o edline.c
edline.c:10:10: fatal error: curses.h: No such file or directory
   10 | #include <curses.h>

You could symlink the contents of /usr/local/include/ncursesw to /usr/local/include

[ovacikar]

You could symlink the contents of /usr/local/include/ncursesw to /usr/local/include

Do I do that using the default configure script or the modified one (hardcoded option 3) ?

[Juanito]

It should work with the default configure script.

Here's the script for x86 and 64: https://github.com/andyj713/tinycorelinux-build-scripts/blob/master/build-iftop.sh. It has fixes for curses, but I haven't tried it on Pi.

Thanks a lot! Worked like a charm.
