How to disable running installation scriptlets during build time

01-17-2008, 03:41 PM

I do a relative symlink
in the post scriptlet. The problem is when I install the package with a
relocation, rpm looks for a dependence on the linked file in its original directory.

Moreover, at install
time, I run rpm from a Shell script which sets environment variables that I use
in the scriptlets, especially to chown delivered files to a user known at this
time only. Thatâ€™s why those scriptlets cannot be ran at build time.

Â*

Does I need just to set %__scriptlet_requires
to %{nil} to disable it ?

Hi,

Building a rpm package, I
noticed that, right now, installation scriptlets are run at build time, during
the "processing files" step. It seems to me having seen on Internet
that this is for finding required files/commands used in those scriptlets.

Â*

There is a means to
automate scriptlet dependencies using bash --rpm-requires.

Â*

In rpm-4.4.4 (and later)
the mechanism for automating has been added

#------------------------------------------------------------------------

# executable(...)
configuration.

#

# Path to scripts to
autogenerate executable(foo) script dependencies,

#

# Note: Used iff
_use_internal_dependency_generator is non-zero. The

# helpers are also used
by %{_rpmhome}/rpmdeps {--provides|--requires}.

#%__executable_provides
%{_rpmhome}/executabledeps.sh --provides

#%__executable_requires
%{_rpmhome}/executabledeps.sh --requires

%__scriptlet_requires
Â* /bin/bash --rpm-requires

Â*

Tokens in an executable
context are parsed as dependencies. E.g. this

scriptlet

Â*Â* Â*rm -rf
%{buildroot}

will generate

Â*Â*
Â*Requires: executable(rm)

and an executable called
"rm" will be checked for on PATH during

installation during
dependency checking, just like which(1) or bash(1)

would do.

Â*

Meanwhile, note that bash
--rpm-requires is not perfect. The patch

to bash needs to be
improved before the mechanism is 100% reliable.

Â*

Is there a way
to disable this execution, because I do some things which cannot be possibly
done on the building platform.

Â*

I'm not sure what you
ask. You can disable the mechanism on the build system,

yes. But the mechanism is
entirely done on the install, not the build, platform if

used correctly.
