ncurses @6.0_0 fails to build on Lion with cxx_stdlib=libc++

[dClauzel (Damien Clauzel)]

Trying to upgrade ncurses from 5.9_2 to 6.0_0 on iMac6,1 running Mac OS X Server 10.7.5 (11G63)

Can’t reproduce in my Lion VM. What Xcode version are you using? And could you please check that you have installed the corresponding Command Line Tools?

[jmroot (Joshua Root)]

Hmm, I see the problem. How is -stdlib=libc++ sneaking in there? Could you attach the config.log?

[dClauzel (Damien Clauzel)]

Replying to jmr@…:

$ xcodebuild -version

Sure; I am attaching it to the ticket.

[dClauzel (Damien Clauzel)]

For -stdlib=libc++, it is possibly related to this : ​https://trac.macports.org/wiki/LibcxxOnOlderSystems

Quite some months ago, I had to add this to /opt/local/etc/macports/macports.conf in order to be able to compile some ports:

cxx_stdlib         libc++
buildfromsource    always
delete_la_files    yes

[gallafent]

I also see this on a fully updated Mac OS 10.10 system using Xcode 6.4:

$ xcodebuild -version
Xcode 6.4
Build version 6E35b
$ uname -a
Darwin forth.lan 14.5.0 Darwin Kernel Version 14.5.0: Wed Jul 29 02:26:53 PDT 2015; root:xnu-2782.40.9~1/RELEASE_X86_64 x86_64

This therefore isn't just a problem on older systems. For what it's worth, I do also have the following lines in my macports.conf:

buildfromsource always
macosx_deployment_target 10.8
configure.macosx_deployment_target 10.8
cxx_stdlib libc++
configure.cxx_stdlib libc++
cxxflags -std=c++14
configure.cxxflags -std=c++14
delete_la_files yes

I'll attach my config.log and main.log, for completeness. It appears that we're explicitly linking libstdc++ when building the demo, which is clearly wrong if we're trying to do a libc++ build … config parameters not making it sufficiently deep into ncurses' build? All the config test results saying that we /are/ using the GNU C Compiler, when in fact we're using clang, are a worrying signal too …

[jmroot (Joshua Root)]

Ah. That’s not a supported configuration at this point, so I’ll close this ticket. If you need it to work, you could report the issue upstream: ​http://invisible-island.net/ncurses/ncurses.faq.html#report_bugs

[gallafent]

For what it's worth, there's a quick hack which will allow the port to build, which is to add the following fragment to the port's configure.diff:

@@ -19311,7 +19311,7 @@
   cf_stdcpp_libname=stdcpp
   ;;
 (*)
-       cf_stdcpp_libname=stdc++
+       cf_stdcpp_libname=c++
        ;;
 esac
 echo "$as_me:19317: checking for library $cf_stdcpp_libname" >&5

As you can see, that overrides the existing forcing of linking libstdc++ with an equally invalid forcing of linking libc++ … which is of course fine for our needs :)

Clearly this should be fixed upstream. I'll post to ncurses' mailing list, linking this ticket!
