#37420: fizmo: Could not find libncursesw

 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.1.2
 Keywords:                |       Port:  fizmo
--------------------------+-------------------------------
 fizmo doesn't build on the Snow Leopard buildbot. Here's the log from
 0.7.6 but it's been happening for several versions:

 https://build.macports.org/builders/buildports-snowleopard-
 x86_64/builds/13274/steps/compile/logs/stdio

 During the configure phase it says:

 {{{
 checking for ncursesw... no
 checking for /usr/include/ncurses.h... yes
 checking for libncuresw in /usr/lib... no
 checking for libncuresw in /usr/local/lib... no
 checking for libncuresw in /opt/local/lib... no
 Could not find libncursesw.
 Try setting the location using --with-ncursesw-libdir.
 }}}

 For one thing, there is a typo in the message ("libncuresw" should be
 "libncursesw").

 But even ignoring that, this is peculiar since libncursesw should be
 there; there should be no difference in ncursesw in MacPorts between
 versions of OS X, and it builds fine on the Lion and Mountain Lion
 buildbots, which simply say:

 {{{
 checking for ncursesw... yes
 }}}

 It also builds fine for me on my Snow Leopard, Lion and Mountain Lion test
 machines.

 The suggestion the configure script gives—to set --with-ncursesw-libdir
 (and presumably --with-ncursesw-includedir)—shouldn't be necessary because
 my understanding is that "checking for ncursesw" means "checking for
 ncursesw ''using pkgconfig''" and pkgconfig should be giving the correct
 answer. But for some reason on the Snow Leopard buildbot it's not. It
 makes me think there's a problem with the pre-built pkgconfig or ncurses
 binary for Snow Leopard. (I build from source on my test machine instead
 of using the binaries.) I wish we had access to the work directory on the
 buildbot so that we could read the config.log; unfortunately we don't.

 Oddly neither of those ncursesw configure options are listed in
 `./configure --help`; if they are valid options they should be listed
 there.

 --------

 Another problem is that the fizmo configure script still exits with the
 code 0 even though this problem occurred, so MacPorts tries to proceed to
 the build phase, which fails with:

 {{{
 make: *** No rule to make target `all'.  Stop.
 }}}

 --------

 I'm also not sure why the code in config-libs.m4 that checks for ncursesw
 is trying to include jpeglib.h; that seems like a copy-pasto.

 {{{
   for dir in $with_ncursesw_libdir /usr/lib /usr/local/lib /opt/local/lib
 ; do
     AC_MSG_CHECKING(for libncuresw in $dir)
     LDFLAGS="-L$dir"
     AC_TRY_LINK(
       [#include <stdio.h>
        #include <ncurses.h>
        #include "$ncursesw_h_dir/jpeglib.h"],
       [initscr();],
       [AC_MSG_RESULT(yes)
        ncursesw_l_dir=$dir
        break],
       [AC_MSG_RESULT(no)])
   done
 }}}
