>Description:
A pkgsrc build of audio/mp3blaster failed on linking due to an ncurses header or library mismatch.

Pkgsrc is pkgsrc-2022Q4.

"undefined reference to _acs_char"

ld: main.o: in function `newgroup()':

I will continue to look at the configure script etc., as mp3blaster should work with ncurses.
>How-To-Repeat:
$ cd devel/ncurses
$ make install
$ cd ../../audio/mp3blaster/
$ make install

>Fix:
Remove ncurses package and re-install mp3blaster.

$ pkgin remove ncurses
1 packages to delete:
  ncurses-6.3nb1

$  mp3blaster -v
mp3blaster version 3.2.6 - http://mp3blaster.sourceforge.net/
Supported audio formats: mp3 wav ogg
Supported audio output drivers: oss
Build features: pthreads

 This is caused by compiling against headers from base curses and
 linking against ncurses, which obviously can't be expected to work.

 I cannot reproduce the problem though. If it's still happening:

   - please check what config.status reports for the various
 curses/ncurses tests;

   - after "make configure" please check in work/.work.log whether the
 transformed commands (the ones marked with <.> rather than [*])
 contain references into your installed package tree (they should not,
 instead they should refer to work/.buildlink);

   - make sure your installed package tree (/usr/pkg or whatever) isn't
 symlinked; that breaks the buildlink logic and that can cause failures
 of this type;

   - if none of the above applies check that work/.buildlink links to
 the right curses (base curses headers and libraries, and not ncurses,
 and definitely not a mixture).

 Before checking the first 2, I definitely use symbolic links for pkg/pkgsrc=
 :

 lrwxr-xr-x   1 root  wheel      9 Feb 15 19:44 pkg -> /home/pkg
 lrwxr-xr-x   1 root  wheel     12 Feb 15 19:43 pkgsrc -> /home/pkgsrc

 I will check the other suggestions. This must be an obscure issue, as
 I have used symlinks for pkgsrc on many previous versions without
 seeing those symptoms.

 Now I cannot replicate the error on the original system or a second one.
 So OK to close as unable to reproduce.

 Yeah, it is fairly obscure. The problem is that the buildlink/wrapper
 scheme rewrites references to the installed package tree (to refer to
 work/.buildlink instead) and this doesn't work reliably if there are
 multiple names for it.

 Which means that now and then something like this happens, but it
 depends heavily on circumstances and usually only comes up if the
 package is trying to be too smart for its own good. In this case it
 appears that mp3blaster's configure script explicitly tries to look in
 /usr/pkg, and for whatever reason it was able to see the ncurses
 library but not the headers.

 Ideally this would be handled better but it's not entirely trivial to
 discover all the names, especially in more complicated cases.
 (Consider for example /usr/pkg -> /usr/local/pkg and /usr/local ->
 /home/local, which is an entirely reasonable setup.) So the solution
 so far has been to say "don't do that".
