Install python pacakge from `.whl` file

[Hamzeh Nasajpour]

Hi,

I have to package a python library via `whl` file, is it feasible? 
I took a look in the guix packages, and found something in `tensorflow` package 
to installing from `whl` file,
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/machine-learning.scm#n1784

but I get these errors when I want to install my package. I'm using the 
following lines in my package definition too:
```
...
 (invoke "python3" "-m" "pip" "install" source
   (string-append "--prefix=" %output))
...
```

Error:

Re: XDG_... env variables in root

[Hamzeh Nasajpour]

Hi,

https://unix.stackexchange.com/questions/7013/why-do-we-use-su-and-not-just-su/7021#7021

Seems that this is relevant to way of switching user which I used. I was using 
`su` for switching as `root` and just now I found that there are some 
differences between `su` and `su -`. With using of `su -` the `XDG_...` env 
paths are correct:

```
$ su -
$ printenv | grep XDG_
XDG_CONFIG_DIRS=/run/current-system/profile/etc/xdg:/root/.guix-profile/etc/xdg:/run/current-system/profile/etc/xdg
XDG_DATA_DIRS=/run/current-system/profile/share:/root/.guix-profile/share:/run/current-system/profile/share
```

Anyway I didn't know there are differences between `su` and `su -`.

Hi Ricardo,

Thanks for your reply.

Yes, exactly, They are doubled, but another issue is these are env variables in 
`root`. My main issue is why these variables in `root` point to `USER` paths?

Do you have any idea? Where and how can I fix them for `root`?

hash guix after guix pull

[Hamzeh Nasajpour]

Hi,

I want to use a custom application for running `guix pull` and `reconfigure` 
after each OS start up.
I developed a python library and put it in the configuration to run it as a 
single-shot service as root.
It will be run but seems that I should update `PATH` env via `hash guix` since 
some of my packages in my custom channel won't be loaded.

```
...
no code for module (px package ...)
--

If I run my python library manually everything works fine (guix pull & 
reconfigure) but I can't run it as a service.

Do you have any idea? Is there anything in somewhere that I missed?

Package building with gcc-10

[Hamzeh Nasajpour]

Hi guys.
I have a cpp Application that should be build with `gcc-toolchain-10.2.0`. I 
could build it in local. But seems that in package building the 
`cmake-build-system` is using the `gcc-7.5.0`. How can I set a specific version 
of gcc for building my package definition?

Re: Error in package building : error[E0463]: can't find crate for `openssl_src`

Hi guys,

Anybody has any solution?  For now I face with this error in package 
installation:
```
...
   Compiling etebase-python v0.30.0 
(/tmp/guix-build-python-etebase-py-0.30.0.drv-0/etebase-0.30.0)

   |^

error: aborting due to previous error

error: could not compile `etebase-python`.
```

This error is related to this line: 
https://github.com/etesync/etebase-py/blob/master/src/lib.rs#L62

Quick review: 
1. I want to package `etebase-py`.
2. the build system for etebase-py tries to also build etebase-rs. 
3. It's using the `setuptools-rust` for installing the rust dependencies.
4. So I packaged `etebase-py` with `cargo` build system, then I can patch the 
build system to installing the python files. In this step I faced with the 
above errors.

This is my package definition:
```

```

indeed, this library is python and internally it's using a rust library. the 
`cpython` is one its dependencies that I packaged it (`rust-cpython`) and it 
needs to it. I don't know how can I add rust  dependencies here since I'm using 
python build system. I added it to inputs but not resolved.

Indeed now the problem is adding dependencies (some of them rust and some of 
them python) to this package while I'm using the python build system. Do you 
have any idea?

Re: Error in package building : error[E0463]: can't find crate for `openssl_src`

[Hamzeh Nasajpour]

Hello John,

Thanks for your following up.

I put the `openssl` in `inputs` too and the problem wasn't resolved. I also I 
packaged the `openssl-src` and repackage the `openssl-sys` and this is didn't 
resolved the problem too. 

The point is with the following package definitions the `rust-openssl-sys` will 
be build/installed without any error, but in the `etebase-py` 
building/installation I get the previous error.

This is my package definition till now. The repository of the package is here:

Also I should to say I package these (since they aren't available in the 
upstream packages):
* openssl@0.10.30
* cpython@0.3
* etebase-rs
* flapigen-0.6

I didn't attach them here for simplicity.

Re: Error in package building : error[E0463]: can't find crate for `openssl_src`

[Hamzeh Nasajpour]

Hello John,

Thanks for your quick reply.

But as you see in `Cargo.toml`, this feature mentioned and I think it's needed. 
In the other side setting the `OPENSSL_DIR` didn't resolve my issue.

Do you have any other suggestion?

Can I repackage `rust-openssl-sys-0.9` and remove this line in the package 
definition? (Sorry I'm not expert in rust and I don't know what's the 
`vendored` feature, but I need this package urgently - `etebasepy` )

```
  (patches (search-patches "rust-openssl-sys-no-vendor.patch"))
```

Hamzeh

Packaging a python package that is using setuptools_rust

[Hamzeh Nasajpour]

Hi,

I want to package the `etebase-py` library: 
https://github.com/etesync/etebase-py/

It's using the `setuptools_rust` for build/install. Also it has some rust 
dependencies that I packaged them. And now I create a package definition by 
`guix import ...`:

Do you have any idea? I should add the rust dependencies to `native-inputs` or 
`inputs` of `etebase-py`? Do you have any package definition that is used 
`setuptools_rust` as example for me?

rust packaging with specific version of rust

[Hamzeh Nasajpour]

Hi,

I'm not expert in `rust`. I need to work with a library that has some 
dependencies to rust and I had to package a few libraries in GuixSD. Anyway now 
I faced with an error in building one rust package:
```
error[E0658]: use of unstable library feature 'inner_deref': newly added
  --> src/http_client/mod.rs:54:25
   |
54 | self.auth_token.as_deref()

   |
   |

```

Based on the following document the  `as_deref()` method is available since 
rust version `1.40.0`.
https://doc.rust-lang.org/std/option/enum.Option.html#method.as_deref

Now how can I build/install my rust package with this specific version? is it 
possible? or is there anything that I forget? Please help.

Why the static library will delete after the package installation of dlib?

[Hamzeh Nasajpour]

Hi,

I'm using `dlib` in a project and I found that the static library will be 
deleted in the `delete-static-library` phase in the package installation. Why? 

https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/machine-learning.scm#n814

Is there any problem to comment these lines for using the `dlib` as library? 
(line 814 - 817)

Re: shepherd as normal user

I'm looking to find a way to configure the `shepherd` with `config.scm` (system 
reconfigure ...). 
The startup script is a workaround but it has some problems, for example, 
multi-login/multi instance of shepherd and so on.

Do you have any idea?

Re: shepherd as normal user

[Hamzeh Nasajpour]

Thanks for your reply.

It's a good example. But my main problem is running `shepherd` as normal user 
automatically.

For now, I've to run it manually.

shepherd as normal user

[Hamzeh Nasajpour]

Hi,

I'm going to run `shepherd` as a normal user automatically (at startup). How 
can I do that?

I know the `shepherd` will be run as root with PID=1 in the init system, but I 
have some services that should be run by `shepherd` for normal users.

Re: undefined symbol error in qtbase

[Hamzeh Nasajpour]

Hi Ricardo,

Thanks for your help.

Now I repackage the `qtbase` and remove the `sqlite` from this line:
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/qt.scm#n536

The problem resolved and the `trojita` installed and run successfully. 

Regards,
Hamzeh

Hi Ricardo,

Seems that `qtbase` has only one dependency to `sqlite-with-column-metadata` 
here:
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/qt.scm#n578

Did you see the `qtbase` package definition? I don't see `sqlite` in it's 
package definition.

Hi Ricardo,

Thanks for quick reply.

Yes, exactly, the problem is in running with this error:

undefined symbol error in qtbase

[Hamzeh Nasajpour]

Hi,

I want to package `trojita` for GuixSD. I created a package definition and it 
was build and installed successfully. When I run it I get the following error:

```
/gnu/store/890yw9i7lcjnnxhlza8r121352xp1hi-qtbase-5.11.3/lib/qt5/plugins/sqldrivers/libqsqlite.so:
 undefined symbol: sqlite3_column_table_name16

```

`trojita` is a mail client application that has a dependency to `qtbase`. I see 
that in `qtbase` package definition there is `sqlite-with-column-metadata` as a 
dependency, Apparently all is ok but I don't know the reason of this error. Do 
you have any idea?

Links:
* `qtbase` package definition : 
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/qt.scm#n578
* `trojita` mail application : https://cgit.kde.org/trojita.git

`scm` file parsing(read/write/modify)

[Hamzeh Nasajpour]

Hi,
I have a configuration file that written based on `scm` file like as `guixSD` 
config.scm file.
https://www.gnu.org/software/guix/manual/en/html_node/User-Accounts.html#User-Accounts


I want to read/write/modify this config file in python or C/C++.
Do you know any `scm` file parsing  or any other solution for my needed? In 
fact I want to add/remove/modify parameters of this config file.

Hamzeh
