Default shell in RPM spec file

[paul.d...@sydac.com.au]

Hi,

I am new to creating RPMs and I'm trying to create my first. I am
trying to package someone elses software and the source must be built
in zsh. I am calling the rpmbuild command from a z-shell but by
putting in a "ps -p $$" command it shows that the shell is /bin/sh.

Is it possible to change the default shell that rpmbuild uses?

I have tried searching the archives but can't find anything.

Thanks for your help.

That is not the most portable way to build things. A /bin/sh assumption
will pop up in many places.

$ rpm --showrc
....
-14: ___build_shell %{?_buildshell:%{_buildshell}}%{!?_buildshell:/bin/sh}
....

In other words - if you did not explicitely redefine your _buildshell
in a spec file then does not matter from what you are trying to call
rpmbuild process you will end up with /bin/sh. That nothing will break
after such redefinition this remains to be seen.

You better do not forget 'BuildRequires: zsh' if you change that or
your specs will be quite broken.

Did you try manuals? That would likely help.
