RPM spec file script: %define command

awfun · 04-02-2014, 06:44 AM

Hello.
I'm trying to create a SPEC file for some program, that might be installed on "server", "client", "other" types of computers. Each type has it's own list of files and actions during installation and uninstallation.
SPEC file describes %install, %pre, %post, %preun, %postun scripts. I want %install script to define a value, that could be used by other scripts, even after reboot.
Example:

Code:

%install
  type="server"
  define _type "123${type}"
  echo "%{_type}"
%pre
  echo "%{_type}"

output:

Code:

install:
  123server
pre:
  123

Of course, %pre scipt does not know the value of ${type} variable. How can I put the value of a local variable to defined one?

Thank you for your answers.

Be careful: %define's are used at package creation time and %install is used to drive package creation, not the package installation afterwards on a (any) system. Often packages following the client - server paradigm are split into sub-packages (openssh-server, openssh-client) so IMHO that's the way to go. If the recommended way of creating different packages per install type doesn't apply (since it's just an arbitrary term you use in scripts) then there's nothing, except placing something on the file system, that you can use, like say 'echo server > %{DOCDIR}/install_type' in your %post section. If you use that or something similar beware of %reloc.
