wxWidgets-3.0-libcxx: remove the port

[mojca (Mojca Miklavec)]

I would like to suggest getting rid of wxWidgets-libcxx (now that we have wxWidgets-cxx11 anyway).

It seems that only FileZilla is trying to use it (it was me who added that weird code long time ago), but I'm pretty sure that FileZilla in its current form is not supported on < 10.9. I don't know whether using cxx11 1.1 would help in any way.

Random note. The libfilezilla library can still be compiled on 10.7. On 10.6 it ​fails to build with the same error as reported here:

• ​https://trac.macports.org/ticket/43203

file.cpp:142:14: error: use of undeclared identifier 'O_CLOEXEC'
        int flags = O_CLOEXEC;
                    ^
1 error generated.

Just as a reference point when thinking about how far back we might want to go with testing.

Replace wxWidgets in FileZilla

[mojca (Mojca Miklavec)]

Yen: I atteched my proposed changes for FileZilla. Can you please have a look. It would probably be most interesting to test this on 10.7 or 10.8. If this works fine, my next step would be to get rid of wxWidgets-3.0-libcxx as there's really no need for it.

Replying to mojca:

file.cpp:142:14: error: use of undeclared identifier 'O_CLOEXEC'

int flags = O_CLOEXEC;

1 error generated. }}}

This error is noted now and then on 10.6.8. Sometimes I have seen it fixed properly, by manually closing the file after using it. Most often, with many examples on MacPorts, it is just defined to 0 like this:

configure.cppflags-append -DO_CLOEXEC=0

fixing O_CLOEXEC gets further on 10.6, but there is at least one further missing function not yet replaced by snowleopard_fixes. Will have to work on this more later, but for now it is still broken on 10.6.
