Specifying Parameters to Macros

Currently, writing a *.spec file for an RPM. How can I dynamically define variables so that they utilize the parameterized macro?

Per the rpm documentation I've come up with following:

1     %define postgresql_macro() (?%1?%2?%3?%4?%5)
2     %define postgresql_ver %postgresql_macro 9 . 4 . 15
3     %define postgresql_ver_short %postgresql_macro 9 . 4 .
4     %define postgresql_ver_major 9 4

Line 1 is the macro that accepts parameters.

Line 2 should define postgresql_ver as 9.4.15.

LIne 3 should define postgresql_ver_short as 9.4.

Line 4 should define postgresql_ver_major as 94.

How can I test this? Is this correct?

First, you have it wrong. it should be:

%define postgresql_macro() %1%2%3%4%5                                                                                              
%define postgresql_ver %postgresql_macro 9 . 4 . 15
%define postgresql_ver_short %postgresql_macro 9 . 4 .
%define postgresql_ver_major 9 4

You can test this way. Put in your SPEC file:

%prep
%define postgresql_macro() %1%2%3%4%5                                                                                              
%define postgresql_ver %postgresql_macro 9 . 4 . 15
%define postgresql_ver_short %postgresql_macro 9 . 4 .
%define postgresql_ver_major 9 4
echo %{postgresql_ver}

And now run rpmbuild -bp your.spec. This should print: 9.4.15
