libzzip @0.13.71 can be built with Python 3

[ballapete (Peter "Pete" Dyballa)]

Since I want to live without Python 2.7 from MacPorts (the macOS one should suffice) I started to change libzzip – which only needs Python 2 to create the documentation. By using Python's 2to3 some Python files were adapted to Python 3 – and the documentation built! It's also usable.

Could be the translation is not perfect, because when building the documentation around 10,000 lines à la

Unescaped left brace in regex is passed through in regex; marked by <-- HERE in m/<([^<>]*)\${ <-- HERE src_dir:[?]([^{<>}]*)}([^<>]*)>/ at (eval 325) line 292, <STYLESHEET> line 19691.

are emitted (this is certainly from Perl). So next TeX Live release could be a bit more up-to-date.

The attached patch files either translate the needed Python files or correct a minor fault in one Makefile.

On High Sierra the same amount of Perl complaints appears – when building with Python 2.7. Here it also works to build with Python 3. (This Perl output also appears when building GCC7 on PPC Tiger.)

are meanwhile installed from source. Looks good, so far!

It might be useful to offer two variants of this port: one with Python 2 and another one with Python 3.

[mojca (Mojca Miklavec)]

This port needs an update. The update requires CMake, so it doesn't make much sense to fiddle with the old configure.

The problem I'm facing now is that the build runs test as part of the build process and now expects the test binaries to have a working /opt/local/lib/libzzip.13.dylib before the build is even complete.

[kencu (Ken)]

to fix that, you set "build with install runpath" to off.

I'll see if I can find a recent example; I often have to do that when I enable testing for cmake ports.
