Installing from Git

[ReformedCharacter]

I need a little help with this:

I'm running an Arch based VM and want to install zziplib from here:

https://github.com/gdraheim/zziplib

I've run git.clone and have the necessary files in a suitable directory but I'm unsure what to do next, the file I want to use is zzipsetstub which currently appears as zzipsetstub.c in the 'tests' directory below zzliplib, along with makefile.in and makefile.am.

I ran 'cmake' from the zziplib directory but I don't appear to have an executable zzipsetstub.

What should I do next please?

I'm afraid that I can't help you with that package. I don't use Arch and I wouldn't be bothering to compile a zip package without good reason.

Is there some reason that you don't want to use this, more recent, zip package?

https://aur.archlinux.org/packages?K=peazip&SB=p
https://peazip.github.io/
https://github.com/peazip/PeaZip/releases/

I have found it remarkably good over the years.

Thanks. Yes there is a reason for that particular package.

Nothing to do with finding the relevant files for your build?
Just reading the cbuild instructions it seems to me that you might need to add the sub-dir paths as ENVIRONMENT variables


“ build: Produce correct pc file with absolute libdir
The CMAKE_INSTALL_INCLUDEDIR and CMAKE_INSTALL_LIBDIR variables
can be absolute paths so simply appending them to \${prefix}
might not work.

Unfortunately, CMake does not have simple function for joining paths [1]
so I had to write my own suboptimal one.

It somewhat handles the following cases

- prefix absolute + libdir relative
- prefix absolute + libdir absolute but not under prefix

but for

- prefix absolute + libdir absolute & under prefix

we would want to strip the prefix and make the libdir relative
so we can make it relative to the pkg-config variables.

Basically, we want the equivalent of the following Python function:

import os.path
from pathlib import PurePath

if os.path.isabs(libdir) and os.path.commonpath([libdir, prefix]) == str(PurePath(prefix)):
# Convert path to be relative to prefix
skip = len(prefix) + 1
libdir = libdir[skip:]

return os.path.join('${prefix}', libdir)

This would be non-trivial to replicate in CMake scripts as far as I can tell.”

Thanks for your replies. I now have what I wanted after looking at the instructions again

Any particular reasons for running Arch other than the rolling release nature of it?

I've never tried it as I've read stories about it being 'difficult', although I note Valve switched from Debian to Arch for the latest SteamOS/Steam Deck.

Yes, I wanted to install an Arch based VM with some useful software:
