Using cygwin 1.7 and gcc 3.4.4 I have a line in a script
gcc -o myexec -o3 ./my.a -lreadline -lncurses -lm
which has worked since the Dawn of Time. Just now I had to rebuild
myexec and got an error message
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld:
cannot find -lncurses
collect2: ld returned 1 exit status
Strange because I have
setup.exe -P {variouspackages},ncurses,{morepackages}
as my one-line setup command (also with a long history of nofail
working). But on inspection I see files and folders
/usr/include/ncursesw NOT /usr/include/ncurses
/usr/lib/ncursesw* NOT /usr/include/ncurses*
all dated Feb 15. Did I miss some massive re-configuration and re-naming
then?
Rewriting the gcc line with -lncursesw not -lncurses works.
However ... I'd quite like to keep this line for the simple reason that
it works in Linux as well as (up to now) Cygwin. I could write a branch
but I'd prefer to write a link something like
ln -s ncursesw ncurses
under /usr/include/ or something similar but presumably more complicated
under /usr/lib/.
Have I identified the cause of the breakage (some kind of supersession
on or about Feb 15)? Have others tripped up? Is there a good cure?
Thank you.
Fergus
