Installing borgbackup on Sonology DSM 7.2-64570 not possible

I try to install borgbackup on my NAS, and I get the following error:

Thanks for help

@barnybla we have a borgbackup package available.

It is not possible to install borgbackup as you did. It is missing some wheels that need to be cross compiled for the system your are running it. I suppose your NAS is not of x86_64 architecture, as wheels for those are mostly downloadable from the index (like pypi).
AFAICS in the logs, it is trying to build cryptography wheel. For this it would need a build environment with development packages, compiler, et al.

If you install borgbackup package created by the SynoCommunity, you get all the required cross compiled wheels for your NAS.

It is one of the main tasks of this repository to cross compile programs, libraries and tools (and wheels) from source code.

---

PS If a program and all dependencies are pure python, then it is possilbe to install it in a virtual environment as you tried.

thanks hgy59 for the reply,
The NAS has a x86_64 architecture. So I should leave virtual environment, and install it in the normal system. Which package, from the SynoCommunity for borg and borgmatic, I should install?

@barnybla ok, you already opened issue #6045, so you were on the right way.

You can add the synocommunity repository to the DSM Package Center (see https://synocommunity.com/) and then install the borg package v1.2.6-14 found in "Community" Packages.

Or you could download the spk file for your model and DSM 7.1 on https://synocommunity.com/package/borgbackup
(chose any x64 arch like apollolake, avoton, braswell, ...) and manually install it in the Package Center.

Lets continue this discussion in #6045.
