Re: Asking for best practices to maintain a debian Ada package

[Stephane Carrez <stephane.carrez@gmail.com>]

Thanks for the answer. I was also quite busy on my side too.

Nicolas gave me some advises in private email.
Your recommendations from both of you were helpful.

I've been able to create my new debian packages.

I've used 7-dev for the development package so that it matches gnat-7.
For example, I get the following packages:

libada-wiki1.1.0_1.1.0_amd64.deb
libada-wiki7-dev_1.1.0_amd64.deb

for my 'ada-wiki' version 1.1.0 package.

I could have put the debian/* files on Ada-France monotone server
but I'm more confortable at using git so for now, I've put them in
https://github.com/stcarrez/ada-debian-pkg

For now, I've not put all the "Build-Depends" dependencies because
if I do it it becomes a nightmare to build since I need to install/uninstall
the 7-dev packages.
