#54421: blackbox @0.70.1 won't build on Snow Leopard, Mac OS X 10.6.8, (cxx_stdlib

Comment (by kencu):

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.

see also [ticket:45577] for a duplicate.

Before I start anew I perform a `port clean blackbox`.

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.

Comment (by ballapete):

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.

Comment (by kencu):

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
}}}

Comment (by ballapete):

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…

Comment (by kencu):

If you look back in the old tickets [ticket: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.

If you look back in the old tickets [ticket:23037], you'll see an old

report from you about this exact iconv thing in this same port 8 years ago

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++.

}}}
