thanks for helping me out! This works as you've written.
However, I now encountered another problem. This time the problem is
with the expansion of %* macro when using nested parameterized macros.
Again, let's take systemd macros as an example:
1) %systemd_post macro [1] is defined as:
%systemd_post() \
if [ $1 -eq 1 ] ; then \
# Initial installation \
systemctl preset %{?*} >/dev/null 2>&1 || : \
fi \
%{nil}
2) %systemd_user_post macro [2] is defined as:
%systemd_user_post() %systemd_post \\--user \\--global %{?*}
(NOTE: This is different that [2]. Here I properly escaped '--user' and
'--global' arguments with two backslashes.)
Using %systemd_user_post macro results in the following error:
[vagrant@localhost ~]$ rpm --eval '%systemd_user_post foo'
error: Too many levels of recursion in macro expansion. It is likely
caused by recursive macro declaration.
if [ $1 -eq 1 ] ; then
# Initial installation
systemctl preset \--user \--global \--user \--global \--user
\--global \--user \--global \--user \--global \--user \--global \--user
\--global \--user \--global \--user \--global \--user \--global \--user
\--global \--user \--global \--user \--global
The problem is that rpm doesn't properly expand the '%{?*}' macro inside
the %systemd_user_post into 'foo'.
Instead, rpm passes it as the third argument to the %systemd_post macro,
where '%{?*}' is then recursively defined as:
\--user \--global {%?*}.
This obviously causes the recursive macro expansion error mentioned
before.
How can I fix the %systemd_user_post macro to properly expand the
'%{?*}' macro?
Thanks and best regards,
Tadej
