Guix build package and publish

[Daniel Pimentel]

Hi Guix,

I'm trying create package with Guix. Initially I choose a simple package 
(ipcalc) but after success I'll create complex package (thanks Andreas 
and Ludo for you advice). So, I'd like help for it :)

My steps (I'm used GuixSD) based Ludo and Andreas talk:
1. Clone Guix repository: git clone git://git.savannah.gnu.org/guix.git
2. Create ipcalc.scm file (in attach) based in gnu/packages/indent.scm 
and update it:
cd guix; cp gnu/packages/indent.scm gnu/packages/ipcalc.scm; emacs 
gnu/packages/ipcalc.scm
3. Add ipcalc to gnu-system.am file:
...
gnu/packages/ipcalc.scm                       \
...
4. Download package: guix download http://url.package.tar.gz
5. Update hash to ipcalc.scm file: emacs gnu/packages/ipcalc.scm
6. Build package: ./pre-inst-env.in guix build ipcalc -K

But there's errors, running with normal user (last lines):
guix build: error: ipcalc: unknown package

Running with sudo (last lines):
./pre-inst-env.in: line 32: cd: @abs_top_srcdir@: No such file or 
directory
./pre-inst-env.in: line 33: cd: @abs_top_builddir@: No such file or 
directory

Help me, thanks.
