blackbox @0.70.1 won't build on Snow Leopard, Mac OS X 10.6.8, (cxx_stdlib = libc++) because – Clang 3.9 is too modern?

[ballapete (Peter "Pete" Dyballa)]

This is a very interesting case…

When I do port -vd install blackbox configure.compiler=gcc-4.2 the build succeeds…

[ballapete (Peter "Pete" Dyballa)]

main.log with Clang 3.9

[kencu (Ken)]

this smells like one of those situations where it is missing a proper -std=c++11 setting. gcc sets these defaults differently than clang, at present. Google is your friend here -- others may have solved this already for you. Or search for this string in Macports, as it has likely happened in other ports too.

if you can't find anything, try something like configure.cxxflags-append -std=c++11 and see what happens.

BTW - you can't mix libc++ and things built with gcc-4.2 without invoking disaster.

[kencu (Ken)]

see also 45577 for a duplicate.

Replying to kencu:

Before I start anew I perform a port clean blackbox.

[mf2k (Frank Schima)]

Given that in #45577, the user was on Mavericks (10.9), I don't think this is a Snow Leopard only problem.

[kencu (Ken)]

Looks like Debian failed to build it with clang also. <​https://github.com/opencollab/clang.debian.net/blob/master/scanlog-3.3-2013-07-14>.

Sorry, I don't understand the mechanics, rules, or whatever behind this. So I cannot ask a worthwhile question.

Same error as without. Could be it's not library but a language problem.

No, I'm not mixing… I don't know what I am doing wrong, but the stuff I compile works. i take some care in not telling my executables – or compilers – stuff. I just presume that my compilers are clever enough to record inside the executables which shared or dynamic libraries from which places they should use in daily life. I really like that sensible software.

[ballapete (Peter "Pete" Dyballa)]

I think the cause for the failure is that Clang assumes a modern C++ dialect used for Blackbox. Clang's man page says that -std=c89 or -ansi should bring Clang in the proper mood. It simply does not work to invoke port -vd install blackbox onfigure.cxxflags-append -std=c89 or port -vd install blackbox onfigure.cxxflags-append -ansi… Port does not use that addtional setting.

[kencu (Ken)]

to append flags (c, cxx, or ld) you have to actually write it in to the portfile (as Ryan pointed out to me a few months ago). I thought you could do that on the command line as well, but you can't.

so if you wanted to test your research, stick something like this in the actual Portfile, to see if it works:

configure.cxxflags-append -std=c89

[ballapete (Peter "Pete" Dyballa)]

Using -std=c89 leads to an error when configure checks whether libiconv is installed ('-std=c89' not allowed with 'C++/ObjC++') and usable.

Since a faulty setting, -stdlib=libc++, is still left

CXXFLAGS='-pipe -Os -ansi -stdlib=libc++ -arch x86_64'
OBJCXXFLAGS='-pipe -Os -ansi -stdlib=libc++ -arch x86_64'

the builds fails at the usual place…

[kencu (Ken)]

If you look back in the old tickets 23037, you'll see an old report from you about this exact iconv thing in this same port 8 years ago :> I guess you really must like this port! I guess you would have to decide if you want to take your chances with the gcc42-built version that somehow finds iconv (how?), or keep digging for the proper fix to this.

Replying to kencu:

But that's not important. -ansi should perform the same, i.e., adapt Clang to an old C++ standard. Without producing the same error. Tested.

From the man page:

       -ansi
           Same as -std=c89.

       -std=language
           Specify the language standard to compile for.

       -stdlib=language
           Specify the C++ standard library to use; supported options are libstdc++ and libc++.

[kencu (Ken)]

fixed somewhere along the way:
