Hello,
I've got linker errors with my program which use ncurses.
Previously it link against librairies in /usr/lib from Apple developper tools.
But since Command Line Tools (HS 10.13), I got:

Like the lib menu is not seen for x86_64, but it seems to be ok:
$ otool -vf /usr/lib/libmenu.dylib

It's really a pity that some libraries coming from Apple fail :-(
I was advised to build the library from source https://invisible-island.net/ncurses.
Though it is available with other building systems, I aim to get it via gtk-osx.
What is the best way to add it?
Pascal,
It's strange enough that something is still using curses in 2019, but stranger still that it uses curses
and Gtk.
Yes it looks strange ;-)
I build a set of Ada libraries based on GTK, ncurses and many others:
https://hermes.gwu.edu/cgi-bin/wa?A2=ind1809&L=GNAT-OSX&P=68
Anyway, the direct answer to your question is to just add it to your local module set just like any other
library that you need.
I've added ncurses in a moduleset:
<repository type="tarball" name="ftp.invisible-island.net"
href="ftp://ftp.invisible-island.net/"/>
<autotools id="ncurses"
autogenargs="--enable-pc-files --without-tests">
<branch repo="ftp.invisible-island.net"
module="ncurses/ncurses.tar.gz"
version="6.1"
checkoutdir="ncurses-6.1"/>
</autotools>
But I need the Ada compiler to be on PATH, I've added it to my PATH but when I do jhbuild it isn't present
anymore!
How to transfert the Ada compiler path to jhbuild?
But first make sure that the symbols really are missing, they're present in 10.14:
$ Manjusri:/Users/john> nm /usr/lib/libmenu.5.4.dylib | grep _unpost_menu
000000000000379a T _unpost_menu
$ Manjusri:/Users/john> nm /usr/lib/libmenu.5.4.dylib | grep _current_item
00000000000024cd T _current_item
000000000000240d T _set_current_item
$ Manjusri:/Users/john> nm /usr/lib/libmenu.5.4.dylib | grep _free_item
000000000000269c T _free_item
$ Manjusri:/Users/john> nm /usr/lib/libmenu.5.4.dylib | grep _free_menu
0000000000002c2a T _free_menu
$ Manjusri:/Users/john> nm /usr/lib/libmenu.5.4.dylib | grep _top_row
0000000000002913 T _set_top_row
00000000000029da T _top_row
It's libncurses 5.4 released in 2004, meaning that Apple has probably not changed it since MacOS X 10.2 or
so. ISTM it's more likely that you've got the wrong link order than that libmenu is missing all of its
symbols.
So mine does:
$ nm /usr/lib/libmenu.5.4.dylib | grep _current_item
00000000000023bd T _current_item
00000000000022ee T _set_current_item
Symbols are present but not seen for x86_64.
Well, I took libmenu.5.4.dylib from an old Snow Leopard macOS with linking success.
The difference between both is that the older one has PPC symbols.
Maybe Apple has stripped out PPC symbols and make it wrong I guess.
