how do I build whipper from downloaded source tarball and no active internet connection?

[themaddoctor]

Hi,

How can I build whipper from the source tarball without an internet connection? I am loathe to build a piece of software that downloads things and installs them without my knowing. So I am trying to build whipple and install it on a machine that has no internet connection, from the source tarball, which I copied over on a USB drive.

Thanks in advance.

I would argue that the specific instructions on how to do this are a bit out of the scope of whipper specifically - it'll be like many other python packages. I would recommend to look at some existing Linux distributions (assuming you use Linux) and see how they build it.

Thanks, but when I do the usual thing, "python3 setup.py build", it tries to open an SSL connection and download other packages without telling me what it is doing. This is forbidden here.

Could you share that output here?

I ctl-C'ed it because it was producing no output while it was trying to connect and download.

[MerlijnWajer]

This looks to me like setuptools is trying to download additional packages that likely aren't installed yet - that is not something whipper controls. These are specified in requirements.txt, setup.py and distributions are also a good place to look, as indicated before.

[themaddoctor]

And setuptools_scm downloads stuff as well, so I feel uneasy trying to use it. Everything else is installed.

Please feel free to ask further questions here, but I think I should close the issue since I don't think this is whipper specific. I appreciate the endeavour (I run Gentoo myself), but I think it's out of the scope of this project. If you find there are specific things that whipper does during the build (like calling wget or something), please do re-open the issue.

Do note that for whipper to function best, it actually needs internet access to query the Accurate Rip database.
