[Nix-dev] Error: invalid printer model name

2017-06-26 Thread Nawal Husnoo

Thanks for your help, I don't really know why I keep missing the obvious :P

I've now compiled the pstocanonij you suggested, but unfortunately:

Jun 20 21:23:51 heisenbug cupsd[21991]: pstocanonij:
/home/nawal/.nix-profile/bin//gs -sstdout=%stderr -r600 -g4958x7016 -q

Jun 20 21:23:52 heisenbug cupsd[21991]: PID 30211 (pstops) exited with no
errors.


[nawal@heisenbug:~/data/nixos/user/pkgs/canon]$ grep "invalid printer model
name" -R ./cnijfilter-common/cnijfilter-3.40/src/bjfoption.c
fprintf(stderr, "Error: invalid printer model name\n");

A bit of googling suggests the "model name" isn't quite what's in the ppd
file...

[nawal@heisenbug:~/data/nixos/user/pkgs/canon]$ grep Name -R ./usr/| grep
ppd | grep Model
./usr/share/ppd/canonmp250.ppd:*ModelName: "Canon MP250 series"

I think this might be where I leave the rabbit hole...

2017-06-21 Thread Nawal Husnoo

Thanks for that Matt!

I wonder if the versioning thing is a windows-related behaviour.

Could you say a few words about the link errors you had? Have you used
patchelf?

>* patchelf --interpreter "$(cat $NIX_CC/nix-support/dynamic-linker)" \
*>* --set-rpath $libPath:$out/lib \
*>* $out/bin/cngpijmonmp250*

Another option I could live with is if we could create a buildFHSUserEnv -
I tried it with the binary canon drivers, but it turned out it's cups that
needs to be inside for the pesky things to be found, but then systemd
wouldn't let me restart cups.service inside a user env...

Cheers,

Nawal.

Thanks for the suggestion! I'm now trying to get it to build as a proper

[Nix-dev] symlink permission denied in builder.sh

2017-06-20 Thread Nawal Husnoo

Hi

I have the following default.nix and builder.sh, copied from the acroread
example and adapted. They are called from config.nix. I'm getting
permission denied when I try to create a symbolic link. Any ideas?

thanks

Nawal

[Nix-dev] printing on nix

2017-06-19 Thread Nawal Husnoo

Hi,

I've got the default.nix below, and I run it using nix-shell. I opened
firefox, and went to 127.0.0.1:631 and added a printer, and selected the
ppd file from /opt/share/ppd/canonmp250.ppd.

Unfortunately, when I try to print a test page I get the error message:

Idle - "File
"/nix/store/wy6c4mlp6zhjj4j3cjwrhwfi4ba9bxab-cups-progs/lib/cups/filter/pstocanonij"
not available: No such file or directory"

The file lives at /opt/lib/cups/filter/pstocanonij.

How do I override cups path in nix?

thanks,

Nawal.

[Nix-dev] Python: Provide your own buildPhase and installPhase.

2017-05-26 Thread Nawal Husnoo

Hi,

Could anyone point me to an example where I can see this in action please?

https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/interpreters/python/build-python-package.nix
# "other" : Provide your own buildPhase and installPhase.

Say I copy the build-python-package-flit.nix file as
build-python-package-panda3d.nix - how do I get my default.nix to use this?

My current attempt:

with import  {};

# nix-shell

# python2.7 makepanda/makepanda.py --everything --wheel --no-egl --no-gles
--no-gles2 --no-opencv  --use-x11 --use-python --use-gl --use-fftw

Re: [Nix-dev] The .nixpkgs/config.nix file and user configuration

2017-05-04 Thread Nawal Husnoo

Using that repo, I have been able to reach what I was looking for: my
system config uses configuration.nix, just for the system, and internet
facing stuff, where I really want to follow the release channel to make
sure I use the latest.

For my user stuff, I now have a config.nix:

$ cat ~/.config/nixpkgs/config.nix
# nix-env -i all
# https://github.com/kamilchm/.nixpkgs/blob/master/config.nix

with import  {};

{
allowUnfree = true;

packageOverrides = pkgs_: with pkgs_; {
eterm = import ./eterm {
inherit (pkgs) stdenv fetchurl pkgconfig imlib2 libast;
libX11 = xorg.libX11;
libXext = xorg.libXext;
libXaw = xorg.libXaw;
};



all = with pkgs; buildEnv {
name = "all";
paths = [
eterm
vlc
];
};
};
}

where the vlc is being pulled from the system channel, but the Eterm is
being built with my modified version of the original, to include the
unicode bits:

$ cat ~/data/nixos/user/eterm/default.nix
{ stdenv, fetchurl
, libX11, libXext, libXaw
, pkgconfig, imlib2, libast }:

stdenv.mkDerivation rec {
name = "eterm-${version}";
version = "0.9.6";
srcName = "Eterm-${version}";

src = fetchurl {
url = "http://www.eterm.org/download/${srcName}.tar.gz;;
sha256 = "0g71szjklkiczxwzbjjfm59y6v9w4hp8mg7cy99z1g7qcjm0gfbj";
};

configureFlags = "--enable-multi-charset=utf-8";

buildInputs = [ libX11 libXext libXaw pkgconfig imlib2 ];
propagatedBuildInputs = [ libast ];

meta = with stdenv.lib; {
description = "Terminal emulator";
homepage = "http://www.eterm.org;;
license = licenses.bsd2;
maintainers = [ maintainers.AndersonTorres ];
platforms = platforms.linux;
};
}

I install all of the above with nix-env -i all, as a user - so this is, if
I understand correcly, per-user as you are seeking too. Does that make
sense?

Re: [Nix-dev] binutils missing libbfd

2017-03-03 Thread Nawal Husnoo

Hi, I found from my old notes that I ended up using simavr before anyway...
so I've now compiled that instead, although the examples and tests gave me
grief so I rm -r themand put a dummy Makefile in the directory. Not tested
it with my code yet.

cheers,
