Lintian's warnings : ldconfig call is useless and unsafe...

[Corentin Desfarges <corentin.desfarges@gmail.com>]

Hi,

To finish my work on fw4spl, I have to fix the 3 last lintian's issues.

 W: fw4spl: postinst-has-useless-call-to-ldconfig
 W: fw4spl: postrm-has-useless-call-to-ldconfig
 W: fw4spl: postrm-unsafe-ldconfig

I don't understand why I get these errors. ldconfig is used to register the shared
libraries. For this warning, I think I'll override the lintian issue as it was done
for a lot of other packages [1]

Here is my postinst script :

 if [ "$1" = "configure" ]; then
  ... && ldconfig
 fi

But about the unsafe call to ldconfig, I thought fix it by adding this in postrm :

 if [ "$1" = "remove" ]; then
  ... && ldconfig
 fi

I've also try to do :

 test "$1" = "remove" || exit 0
 ... && ldconfig

But it doesn't fix the issue, as expected... Is it not safe ? And why is it
useless ?


Thank you for your help,

Best regards,


Corentin
