[Libcdio-devel] -lcurses and keypad()

[Steven M. Schultz]

Hi -

        On a SuSE 9.2 system I first encountered:

gcc -g -O2 -Wall -Wchar-subscripts -Wmissing-prototypes -Wmissing-declarations 
-Wunused -Wpointer-arith -Wwrite-strings -Wnested-externs -Wno-sign-compare -o 
.libs/cdda-player cdda-player.o cddb.o  ../lib/driver/.libs/libcdio.so 
-L/usr/local/lib /usr/local/lib/libcddb.so -lcurses -lm
/usr/lib/gcc-lib/i586-suse-linux/3.3.4/../../../../i586-suse-linux/bin/ld: 
cannot find -lcurses
collect2: ld returned 1 exit status
gmake[3]: *** [cdda-player] Error 1

        That's because 'libcurses.so.1' did exist but NOT a plain libcurses.so

        So thinking it was just a case of a missing symlink I created a
        libcurses.so -> libcurses.so.1

        Then the error becomes:

gmake[3]: Entering directory `/usr/local/src/libcdio-cvs/src'
/bin/sh ../libtool --mode=link --tag=CC gcc  -g -O2 -Wall -Wchar-subscripts

        On modern systems 'curses' (libcurses) has been replaced with 'ncurses'
        as in -lncurses.  keypad() is only defined in libncurses.

        Changing the link command above to use '-lncurses' worked - the link
        completed successfully.

        So I think the test needs to be for 'ncurses' rather than 'curses'
        somewhere.

        Cheers,
